Surprised

When something is easy and does what it says it will do and beyond ,I am always pleasantly surprised. Now I can look forward to better health in peace.

Helpful

This app is so useful! There is no way I could’ve figured out all of my food sensitivities without food marble tracker. This did in two months what years of journaling could not.

Life saver!

This device and app are a lifesaver! I have Methane Predominant SIBO and my doctors had no way to test for methane. Without this device I would not have been able to get the care I needed. I can’t say enough good things about FoodMarble.

The device is clunky and the app is hard to use

When I first started using this several weeks ago, I could not get over how challenging it was just to input a simple meal. The barcode scanner that the app comes with can’t actually get a clear shot of a barcode to scan. I have an iPhone 16 Pro with the three cameras and still could not get a clear shot of any barcode. Typing everything in manually is clunky.

I just took my first Discovery Challenge. And, spent the last three hours starving myself to test Inulin. Three of the six breaths I took on the device came back β€˜insufficient’. So that when the test concluded. I got a message that read β€œnot enough tests or the duration is too short to determine food compatibility.” WHAT????

You’re going to tell a person who has been starving themselves all morning that they just sat there for over three hours to run a test that isn’t even conclusive?

For the price you pay for this device. It is not worth the hassle. I’d love a refund or at the very least the Inulin powder packet resent, so I could try to test again. I am beyond frustrated!

Food Data Base

The food data base is less than basic … I can’t add Broccoli sprouts, fresh garden salad, everything I scan I have to take a picture of so it can read.. they should partner with a platform such as Cronometer

FAQ

What does the FoodMarble app do?

The FoodMarble app works with a personal breath testing device to measure fermentation levels in your gut. It analyzes how your body responds to different foods, helping you identify potential intolerances and gain insights into your digestive health.

How does the breath testing work?

After logging your food, you take a breath test using the AIRE device. The app then analyzes the hydrogen and methane gas levels in your breath to assess gut fermentation. This process helps pinpoint foods that may be causing digestive discomfort.

Is the FoodMarble app free to use?

The app itself is free to download and use for tracking and analysis. However, it requires the purchase of the AIRE 1 or AIRE 2 breath testing device to perform the actual breath tests and gain full insights.

What kind of digestive issues can this app help with?

This app is designed to assist individuals struggling with digestive problems such as SIBO and IBS. It helps uncover foods causing intolerances and provides insights to enhance daily digestive health by understanding gut responses.

Can I track more than just food intake?

Yes, the app offers comprehensive digestive tracking. You can log your diet and symptoms, as well as track your stress and sleep patterns, providing a holistic view of your gut health alongside the breath test results.
