Take the mystery out of food. Find out which foods are more likely to cause problems such as pain and bloating and which foods you can eat without worry.

AIRE, by FoodMarble, allows you to learn more about the way your body reacts to the foods you eat. You can use this app on its own to log your diet and track your digestive symptoms throughout the day, as well as to rate your sleep quality and stress levels. You can also connect to a FoodMarble AIRE breath analyzer, the world’s first personal, portable hydrogen breath analyzer, to track your gut fermentation levels throughout the day.

TRACK YOUR FERMENTATION LEVELS. There are billions of bacteria living in your digestive tract in what is known as the gut microbiome. The bacteria living there digest the food you eat in a process called fermentation. Fermentation is not necessarily a bad thing, but studies show that symptoms such as bloating, cramping, diarrhea and constipation can correlate to high levels of fermentation in the gut.

By connecting to a FoodMarble AIRE hydrogen breath analyzer, you can monitor your fermentation levels throughout the day. Track your Fermentation Scores on a 0-100 scale. Record your Fermentation Scores after you eat various foods. See which foods cause higher and lower fermentation rates and which foods, sleep and stress levels correlate to better and worse symptoms for you.

LOG YOUR FOODS. Log the foods you eat throughout the day. You simply take a picture of the food you eat, add some text, and AIRE records the date and time. Apple Health integration available.

RECORD YOUR SYMPTOMS. Track the digestive symptoms you experience throughout the day. Keep track of when you’re feeling well or having symptoms such a pain, bloating or cramps.

MONITOR YOUR SLEEP. In order to live a healthy life, it is important to have proper sleep habits. With AIRE, you can keep track of how you have been sleeping to see if there is a pattern with your symptoms.

RATE YOUR STRESS LEVEL. Stress can play a role in our digestive system and the symptoms we experience. AIRE allows you to grade your daily stress levels.

PERIOD TRACKING. Can track your monthly and see how it affects your digestion. Apple Health integration available.

TEST YOURSELF AGAINST FODMAPs. “FODMAPs” are natural ingredients found in nearly every food we eat. Many healthy fruits, vegetables, grains and dairy products contain FODMAPs. For some people, certain FODMAPs cause digestive problems such as abdominal pain or bloating. With FoodMarble’s AIRE breath analyzer, you can test yourself against different FODMAPs to find out how your body reacts to these ingredients.

FODMAP FOOD DATABASE. FoodMarble’s food database indicates which foods are high and low in FODMAPs. After each FODMAP test, the food database will take account of your results, to show you which FODMAP-containing foods, you may be able to tolerate.

SET REMINDERS. Set reminders to take breath readings, or to log food, stress or sleep.

CUSTOMER SUPPORT. You can contact FoodMarble instantly through the app at any time by clicking on the “Contact Support” link in the Settings tab.

Needs more Americanization

So far I think this app and device well help me, though it’s early days. One gripe I do have so far is that the food database seems to be missing some stuff, for instance where’s oatmeal, corn/maize, chili pepper? And where are American measuring units like cups, teaspoons, ounces etc? These issues aren’t a really big deal but it would still help to fix them.

Developer Response ,

Hi Sashazur, thanks for the feedback, we are planning to launch a food database specific to the US, since there are a lot of differences in spelling and what people eat, of course.

From a Dietitians Perspective

Food Marble is a great device that allowed me to become more in tune with my body and learn what sugars I can and can’t absorb. For someone who struggles with IBS, I am always interested in ways on how to identify foods that trigger “flare ups.” Food Marble allowed me to pinpoint foods that trigger GI symptoms and ways to lessen the effects or avoid those foods completely.

As a dietitian, I would recommend this device to patients who are struggling to pinpoint their GI triggers through certain FODMAP foods. This device, in conjunction with the downloadable app, also provides various food alternatives to allow for a wide selection of foods, while limiting foods that cause GI symptoms, as well as a food diary to help keep track of symptoms and foods eaten. It’s so much easier than writing everything down! The part that stood out to me the most on being super innovative and interesting was the fact that the device was able to read how much hydrogen was being released from my breath and transmit that information to the app. To me, that was the coolest thing I have ever experienced with the device and app.

Thank you to Food Marble for allowing me to try this product, I really appreciate it.

Confusion about the device purpose

Thank you for creating a unique device, but I am consistently getting a 10 reading, but the manual says this is OK because it could be coming from the large intestine, so how do I know if it’s coming from the small intestine as in case of SIBO. Should I take the measurement first thing in the morning before eating, and once again after eating? The device should have a wider range, or a switch that would bypass some of the air Like a volt meter range, if the reading is pegged at 10, You don’t know what your range is it could be 50 could be 100 it would be 200, what does 10 Mean?Please increase the range of this device, also add a sensor for methane gas.
