Check out the brand new free iPhone app that helps you identify the hidden food sensitivities that make you weak. Hidden food sensitivities are like kryptonite – they cause chronic inflammation, make you tired and moody, and sabotage your fat loss. The free Bulletproof® Food Sense™ app uses your phone’s onboard sensor to get data about what your body does after you eat, so you can identify and eliminate problem foods in order to perform to your maximum potential.

This app is a brazen attempt to use biohacking technologies in an iphone app meant for everyone’s benefit.

After years of knowing that heart rate data is useful for detecting food sensitivity data, but not having a convenient way to use it in the real world, it’s exciting to work with SweetWater Health™ to make this type of technology convenient and accurate enough to use. The alternative is a lab test, which costs a lot of money and involves needles.

You can use this app to decide if it’s worth your time to get a full blood allergy test, or you can use it to help you know what foods to avoid without any lab test at all. I recommend you get a blood test for food allergies unless you feel awesome all the time without fail.

This is an example of how powerful it can be to gather and analyze data from your own body and use it to upgrade yourself. The Food Sense app isn’t meant to be used all the time. Just use it when you’re testing new foods to see how it helps you zoom in on your unrealized food sensitivities.

This app is free because everyone performs better when they are more aware of what is going on in their bodies. You don’t have to eat  the Bulletproof® Diet or drink Bulletproof® Coffee in order to use this app to feel better. Whether you are a biohacker or just concerned about your health, Food Sense™ helps you in your quest for optimal performance and a healthier life. Try it out, see if it works for you, and let me know what you think!

The Quest to Bring You This Technology

When I first started down the path of biohacking and upgrading myself, I was fascinated to learn of Dr. Arthur F. Coca’s research that shows how the heart rate raises, by at least sixteen beats per minute, after you eat foods you are sensitive to.1 As profound as this research is, I found it wildly inconvenient to continuously measure my heart rate, gather the data, and analyze it to help me discover which foods were inflammatory vs. which ones just weren’t for ME. Of course this specific quest was before I fully developed an understanding for the larger relationship between common inflammatory foods and biochemistry in the majority of all people. It is one thing to know your sensitivities and another to know about inflammatory foods in general. More often than not they go hand in hand.

Then, in 2009, I was CTO of a company that makes heart rate monitor wristbands. I became interested in using wristband technology to gather data on food sensitivities, but soon realized that there was no real mechanism for doing that in a watch.

When I started working as an advisor to SweetWater Health™, a heart rate variability monitoring software company, I jumped on the opportunity to partner with them to create the Food Sense app. I was amazed to see how accessible and user-friendly they made the technology I have been dreaming about for years.

How the Food Sense Test Works & Why Eliminating Hidden Food Sensitivities Can Make You Think, Feel, and Look Better

food-sense-screenshotMy experience as a biohacker who used to weigh 300 pounds and really struggled with food cravings, is that every single person has a set of things in their environment or their food that makes them weak, and most people don’t know what most of them are. The Bulletproof® Food Sense app offers a food sensitivity test, using methodology developed by Dr. Coca, to help you identify what is causing the weakness. If you are sensitive to certain foods, you may not experience symptoms right away, though your body reacts by elevating your heart rate for up to 1 ½ hours after eating an offending food.

Food sensitivities are a reaction from the immune system or a result of the body’s lack of proper enzymes to digest foods. When the body reacts to a food, it sends out inflammatory proteins and cortisol, which create low-level chronic inflammation. This type of chronic inflammation may impair digestion, cause sore joints, headaches, and brain fog. Inflammation also triggers weight gain because it affects a specific part of the brain (the hypothalamus), causing it to become insulin and leptin resistant. Decreasing inflammation is critical to any effective fat loss protocol, including the Bulletproof Diet. Unfortunately, a person with low-level inflammation often does not connect the symptoms with the foods, or may not even be aware of them.

This is where easy-to-use self-tracking tools like the Food Sense app come in handy. The Food Sense app uses the iPhone camera sensor to take quick and easy heart rate measurements at specific times of the day. You use the app to measure your pulse first thing in the morning to get a resting heart rate as a base to compare to. Then, before eating a meal, you record what is on your plate and perform a quick pulse test again. After the meal, the app will prompt you to measure your heart rate three times, every 30 minutes after the meal. Once testing is complete, the app determines if the meal triggered a food sensitivity, indicated by a red “X” or if not you will see a green checkmark.

While people can also use one of the affordable heart rate monitors compatible with the app, the camera sensor is a convenient way for people to adopt the food sensitivity test into their everyday life. Using the camera sensor merely requires holding the tip of your index over the iPhone camera lens and flash. No needles. No blood.

I used technology similar to this years ago, but it was too much work to take my own pulse using a little finger attachment, writing it all down, and analyzing the information. This app makes this process really simple and recordable.

Stress and HRV Training Features for High Performers Are in Full-Featured Version of the App

If you want to get a bit nerdy and serious about your performance, you can also get an amazingly full-featured version of the app that works with a compatible chest strap to measure and track your heart rate variability (HRV), the variation in the time between heartbeats, all day long. HRV is a great way measure of a person’s stress level and this app is able to tell you when you are “unconsciously” getting stressed or moving into a fight or flight response throughout the day. In fact, users can see their HRV in real time, giving them the ability to take action to manage stress during a 5-minute breathing and relaxing session. Doing these sessions can help you return to a more relaxed, higher performing state, even in demanding business environments.

This application does not compete with my friends at Heart Math who make the Inner Balance sensor, which you use to train your HRV for short periods, not track it all day. The two HRV apps actually work well together to train your nervous system for optimal performance.

In competitive sports, studies show HRV to be an effective metric to detect overtraining. The full-featured app measures HRV for training, recovery, and provides an objective measure of your body’s response to each workout. The athlete simply does a 3-minute HRV session each morning to determine a result that recommends, “train as usual”, “low exertion day” or “rest day” based on the athlete’s baseline trend.

The app even allows users to upload their data to a secure database in the cloud so they can access their data on a compatible Bulletproof website. Users sign in securely to see a calendar of their sessions, color-coded by average stress level, session tags, and session summaries.

Bulletproof Recommendation

For overall food allergy testing, the Bulletproof recommendation, if you can afford it, is still to get a blood test that looks at your antigens (IGE and IGG). These two tests will help you map out which foods on the test you’re sensitive or allergic to. However, if you eat out at a restaurant or eat mystery processed foods on occasion, that weren’t on the blood test, the Bulletproof Food Sense app will let you know if you have sensitivities to them.

So again, you don’t have to use this app all the time. Use it for a few days in a row to help you zoom in on your kryptonite.

Food Sense is available for free so you can try it out, see if it works for you, and let me know what you think!

    How ’bout for Android phones?

    • Epicurus

      I agree. Apple is for tech illiterate people anyway.

      • Eric

        Or people who have a hearty income, lol.

        • lance

          or people who actually like apple products, I am a techy and love playing with all tech but from a functionality and ease of use I prefer an iphone.

          BB is poor in apps, playbook is good hardware but again apps are poor, iPad device quality is good and seamless in its use across all the apple products and well integrated. A well designed product (any product like BP diet) is something that is easy to use and makes life easier and works.

          For the rest of the time I will test and play with anything but love non MS stuff.

          First testing results have been interesting, Looking forward to see what results I get going forward.

          ” from a functionality and ease of use I prefer an iphone”

          Interesting how different people’s perceptions can be when it comes to operating systems. I would have said the exact same thing about android.

    • Joe E.

      It won’t work because it relies upon iphone’s camera/sensor. Android phones are not unique, there’s so many different brands. Although they could put an app out with simple BP info on it. You scan a bar code and it rates the food. But then again, most foods with bar codes are not BP. I’m trying here.

      • Amber S.

        Androids do indeed have a camera/sensor that would work if it is simply monitoring your HR as stated in this article. I actually have two versions on my phone, one that anazlyzes my HR and gives me feedback on my stress level and one that just gives me my HR at any given time. I am an RN and have used my phone and a machine at the hospital at the exact same time to test the realiability of my phone apps and they are on par. That said, can we PLEASE get an Android version of this Dave?!

    • Yash

      Android users can use the Free Azumio HRV app…same principle…keep your finger on the camera and it will calculate your Heart Rate Variability which you can then log into a cloud database. That’s how I discovered my gluten intolerance. :D
      Ps: The app was recommended on Quantified Self, thats how I got the idea.

  • Sebastian

    Please, I beg you, make an android version.

  • Pete A

    Me too, of course! Android rules.

  • SherriB

    Yes please. We Android users would love this app as well!

  • MT_Dreams

    I’m not sure if an andriod app will come out, hopefully it does. In the meantime, anyone who does not own a iphone should download a pulse reading app (it should be free), unless you already own another device that can check ones pulse. With this you can measure you’re heartrate in the morning, before bed, and before and after eating. It will get the job done until there’s app for andriod.

  • Stridar

    Android version please :)

  • Dave Asprey

    I get it – you want Android. I do too. But I only had the budget to
    develop for one platform, and this was the right choice. I want Android
    too, stay tuned…

    • bp69

      I have an android but will the app work on apple devices such as the ipodtouch?

      • MaryValley

        Good question. Did you find the answer?

        • Jon

          It won’t, the ipod touch doesn’t have a camera for the HRM.

        • Alleycat

          It will work on the iPod touch , iPad or older iPhones with either the manual entry method or using a Wahoo Fitness run pack heart rate monitor.

    • Steven Burrell

      I hope Mr. Asprey you realize that Android has taken over the majority of market share. That it may be likely more consumers and thus your BP readers use Android platform. Now I am not for segregating useful apps to any one platform but if you are going to only develop for one it should be the one more people have access to IMO.
      Samsung alone out competes Apple phone sales (excluding tablets, ipad is still highest selling tablet).
      Many here including myself follow your BP program and purchase your products as it is so hard to find items that are truly made BP. There may be free alternatives on android for measuring heart rate already, but these are not designed around food and stress logging the BP way. I only bring my two cents into this topic because this is your second iOS only app. I hope this information can help in future decisions designing for mobile devices.

      Hey Dave,

      Just wondering if you have heard of Apache Cordova? It is a platform for developing smartphone apps using common web technologies like HTML5, Javascript, CSS, etc. coupled with APIs to access onboard devices. It’s meant for cross-platform development, and can be used with a few different IDEs for compiling the APP for different smartphone platforms, and since it allows you to use JavaScript, you can use libraries such as SenchaTouch or JQurey Mobile for touch compatibility. It might be the better way to develop this, or other apps in the future to offer them on multiple platforms (because clearly you have made some folks angry.) :-)

      Anyways, just downloaded the app, and will play with it this week. Love all the stuff you are doing here. Heard about you on the Joe Rogan Podcast, and have been trying to get bulletproof ever since. So far so good.

      -Josh-

  • Scott

    Installing now. Looking forward to trying this out!

    Also, just came across this article about an app to track diabetes:

    http://knowledge.wharton.upenn.edu/article.cfm?articleid=3314

  • Jim

    Seriously—Last night I was thinking “I wonder why Dave doesn’t have an app yet?”!

  • Mani

    Does the full-featured-Version (HRV) work with the ithlete-dongle?

  • Sjors Provoost

    Since I make apps myself, I can’t help but give some feedback on the first 60 seconds of using it:

    The first thing I saw was a disclaimer. It’s actually possible to add your own terms and conditions in iTunes Connect, so Apple can present them in a more consistent manner. More importantly, the disclaimer speaks about “SweatBeat”. I just downloaded an app called “Food Sense” by “Bulletproof”, so my first thought was “who on earth is SweetBeat”?

    After I agree it asks me to create an account. I’m glad this is optional, but I think it’s better to not even suggest this until it becomes useful to the user, e.g. after one or more measurements. Also again, who is SweetBeat? I just downloaded the BulletProof app and now this unknown entity SweetBeat wants my personal details.

    Now the app says “Good Morning” and asks me to measure my morning pulse while lying in bed. I’m looking forward to doing this, but of course I didn’t download this app when I woke up. Maybe you can make the app say something like “What time do you plan on waking up tomorrow? Would you like me to remind you to measure your pulse first thing?” and then set a local notification or create a calendar event with a reminder.

    Because I have to wait until morning before I can actually use the app, there should probably be something I can do right now to get me more engaged with the app. Maybe just measure my pulse before and after lunch, even if it’s not super useful. Just so I don’t forget about the app and so I’m familiar enough with how it works that I can use it with my foggy head in the morning.

    Anyway, I’m looking forward to play with the app more and see how it will evolve.

    • Tubba

      I’d like to suggest adding a way to practice taking your pulse with the camera/flash as something that can draw people into it before the am pulse check. I’ve never done that before and am wondering if there’s a specific way to put your finger on (top to bottom, left to right).

      Also to note if we should sit quietly after eating for 1.5 hours during the time span of the rest of the measurements or if you can be more active (walking, etc.). Obviously exercising strenuously would put your heart rate up but would walking quickly also do that? I’m really looking forward to using this app, thanks so much Dave!

      • Alleycat

        Dr Coca claims that during “normal daily activities” your heart rate does not vary much. While sitting quietly at your desk or watching TV might be preferred, and high stress or exercise will likely cause a false reading, you should be able to go about normal daily activities and have it work.

  • Matt

    This is THE SAME app as the Sweatbeat Heart Rate Varibility App. It just has a different icon pic…

    Very original :/

  • Epic Coach

    It looks like it will not tell you which food or food chemical you consumed during that meal that you are sensitive to however. One usually eats 20 to 70 different foods and food chemicals per meal. This being the case, the person would still really be left in the dark without having a blood test taken.

    Android Users – I found this free app which measures HRV. Seems to work well on my Galaxy S3. https://play.google.com/store/apps/details?id=com.azumio.android.stresscheck&hl=en

    • Steven Burrell

      I have trouble wondering why these apps are only for apple but when you look at the reviews for the apps, they don’t work very good, or you can get very similar functionality from free alternatives. Maybe it is better these aren’t on android, as we can basically get the same measurements for free. The last iOS app to replace the emwave cost $99 and you can use any camera measuring device for free. Not to mention the poor reviews from the people who paid for the $99 app.

  • http://contrast2.wordpress.com Brandon Adams

    Used it for the first time this morning, and I can report that it does what it claims to do. The camera sensor seems to work. Bad news is my kryptonite is bulletproof coffee. HR shot up 23 (75-98) and my body definitely felt stressed (burning stomach, pressure in eyes, irritability)

    Lots of variables involved (this was only the second morning I’ve tried adding collagen) that I need to troubleshoot, but at least the app is helpful in that troubleshooting.

    Btw, I’ve been getting a burning sensation in my gut if I have 2 tbl of high octane or MCT (as opposed to 1, where I seem to be fine). I’m not getting any cramping or disaster pants. Anyone know what this might point to?

    • http://contrast2.wordpress.com Brandon Adams

      Turns out low stomach acid was the culprit. I had this several months ago when I first started BP and was eating too much protein. Got it sorted out pretty quick with some Betaine HCL.

      I have several food sensitivities and accidentally ate a couple of them 3 weeks ago a few days apart (gluten & yeast). There is a correlation between gluten sensitivity and low stomach acid, and it would appear that this episode depleted my stomach acid, which caused the irritation from BPC + collagen, and any other meal. It would also seem to explain why my body aches have returned. They went away when I got off my food sensitivities and supplemented with Magnesium. Low stomach acid can hinder absorption of nutrients (not certain if specifically magnesium).

      Anyways, just listing it here for anyone who stumbles across searching. I bought another bottle of Betaine HCL and have been taking about 7 capsules with meals. Things seem to be returning to normal. Last time I only had to do that for about 5 days.

  • Modern Minimalist

    First of all thanks for putting a very useful tool out there for the public. Very cool!

    Some initial feedback:
    -Like many others I would also love it on android since that is my primary phone
    -The Android Azumio HRV app takes the pulse much quicker than the bulletproof app (about 10-15 seconds compared to the 80+ seconds on the bulletproof app). Over the course of a day tracking 4 measurements for all meals that is a substantial waste of time. Hopefully that can be improved.
    -The time needed to constantly stop and measure your pulse makes for a tedious experience. Ideally I would love to have this type of tool integrated with a basis watch or some tool that constantly tracks your pulse for a seamless user experience that would just involve inputting meal info and the rest could be automated.
    -Exercise causes major changes to resting heart rate for me. Would like to see instructions on how to deal with eating near non-sedentary portions of the day.

  • Meghan

    HELP!I used it yesterday no problems… but today it won’t read my first pulse??? I did the morning then worked out, came home sat down before breakfast and tried to measure my pulse before the meal and it counted down but then it goes right back to the screen that says “Ready for your 1st Reading”…. so I tried doing the manually entry and it did the same thing… it’s not registering ;(… What to do????

    • Laura

      I had a similar problem, Meghan. It took my morning and 1st meal pulse just fine; however, it would continue to prompt me to measure my pulse again for the second meal. I would do so, and it would again prompt me to take my pulse again–not registering my pulse. I seem to be “stuck” at the “Ready for 1st Reading.” Most likely operator error, but I’m really sad that I’m essentially “stuck.” LOVE the app, but hope to figure out what I’m doing wrong….

  • Meghan

    How many times do you have to test a food? i.e… I eat basically the same breakfast every morning… I’ve done the test twice with the breakfast with an “ALL CLEAR” green check… so am I to assume it’s ok?

  • Michael

    Downloaded the app, used it for a few days in a row. Was very surprised how well the sensor with the camera worked. One night went out to dinner and didn’t go for a very bulletproof meal. Was stunned when my heart rate for the next 90 minutes was almost 20 beats higher! Thanks for bringing this out!

  • pantograph

    Worked for a couple of days, but now won’t get past manual pulse for first meal (as other shave noted), so it has been deleted. It did show that Endangered Species 88% chocolate jacks up my pulse, but BP Cocoa and Lindt 85% bars are OK. Must be mycotoxins.

    Also would be great if camera sensor worked on iPads, not just iPhones.

    Really exciting technology that I will be sure to share with my blog readers!

  • Erik Uhl

    I’ve been using the app, and like it… and I can’t wait for a few updates. Here are a few ”must have” suggestions:

    1) Time Variability. The app assumes your schedule.

    The app is about variability, but ‘night’ is set as is ‘morning’ by your mobile device’s clock… so if you work 2nd, a modified 2nd, or 3rd shift your out of luck on taking your ”pre-sleep” BP at 2am because the unadjustable app says it’s morning now!

    2) Sliding Scale on mobility/work – The app assumes you don’t work for 90min after eating

    If you use the app for breakfast or lunch, and you wake up less than 2 hours before you go to work… you take your BP, then get up, prepare the food, enter it eat it and run to work; you’re moving and sometimes pretty fast… this might raise your BP by ordinary methods other than food sensitivity. Likewise with lunch.. My part-time job in the morning *can* throw off my morning test if I sleep a tad longer… and at ‘lunch’ during my full-time job I only get 30min to eat (hopefully bringing homemade food) but if I have to grab n go (as paleo or BP as possible) that run-n-rush will spike the BP and affect the test.

    These are 2 of the issues I’ve encountered using the app.. and would love to see a little more custom control or flexability in adjusting this tool to work for every individual’s particular n=1 situation. I have no doubt it will be coming down the line in updates, but I figured I’d mention it in the hopes of hastening it’s implimentation.

    The app is awesome, and I can’t wait to find time to breathe (usually saturday) to research and see if a non-athelete would still find the paid version useful. More data never sounds like a bad thing.

  • pablo tacchini

    what about the android app!!!!!!!!!
    thanks anyways

  • Roisin

    This app sounded like a cool idea, but apparently I don’t have a detectable pulse. No matter how many times and ways I try to get the camera sensor to take my pulse, it can’t find it. I can barely find it to take it manually, so I guess I can’t entirely blame the camera.

  • jameswhat

    Thank you very much for the food sense app. Sadly the camera heart rate monitor doesn’t work very well on me. It takes me forever to get a pulse, I’ve tried and don’t have this problem with other heart rate monitor apps. Perhaps some tuning options would help, Cheers! j.x

  • Avalonna

    Where is the data supporting the premise behind this app? I did a quick Google search looking for information about a rise in heart rate related to a food sensitivity, and the only information I could find was on blogs and alt-med sites. The only mainstream sites that mentioned heart rate testing and food sensitivities claimed there was no evidence behind the theory, and indeed, you list one reference, from 1956. Has this theory been tested at all in any kind of scientific way? I considered downloading the app, but after finding no data on it I’m not going to bother.

    Really would like to see Android version fast. Maybe Kickstarter or some other charity program would help to fund it (not familiar with these). Sure there are wealthy people reading this blog and who want to contribute to Android version?

  • krassus

    I wonder how accurate these apps are at tracking your certain body dynamics. For instance, I had an app that used the phone camera to track your heart rate so that it tells you the level of stress. That thing would never point out that I was stressed. I do not want to debunk anything or undermine the usability of these wonderful tools, but I would love to see how accurate these tools are at reading and giving us feedback. I gotta say though, it is a great idea. I would love to see other features for this app such as allowing for other input devices other than the camera, as we can get more precise measuring input devices.

    • krassus

      take it back after reading the comments, the reason for little data and enhanced functionality is simple…takes money and time. Time and time again, I am noticing the importance of measuring the heartbeat dynamic. It seems like the heartbeat is essential in allowing one to determine their well-being. If asprey is reading this, he should probably invite a new age cardiologist or someone that has more knowledge about how the heart tells a story, beyond the normal dynamics that a traditional cardiologist is able to talk about.
