Reviewing your Breath Test Data and Trends
Welcome to the FoodMarble app
The FoodMarble app is packed with features to help you track and understand your digestive health. One of the most important features is breath testing, along with the ability to review your breath test results and other logged data over time using Trends.
When you first get started, you’ll be guided to connect your FoodMarble device to the app via Bluetooth. Once connected, you’ll begin with practice breaths, followed by your first breath test.
Each time you take a breath test, your results are instantly available in the app. The same goes for other logged data!
Viewing your data > Home Screen is today's snapshot
To view your latest data:
- Open the FoodMarble app
- Tap Home in the bottom menu
The Home screen opens on the Today view, where you can see:
- Your most recent breath readings presented on a graph showing fermentations levels low to high
- Meals logged with total RDA (Recommended Daily Allowance) indicated in the RDA ring
- Symptoms logged and their severity
- Sleep quality (from the previous night)
- Poop form
- Stress levels
- Medications (for tracking meds and supplements)
- Notes
Viewing Trends (Historical data)
To view past data, switch to the Trends tab at the top of the screen.
Trends allows you to explore your data in different formats:
- List
- Day
- Week
- Month
Select your preferred view to explore your data.
If you’ve logged enough information, the Month view can provide useful insights. Scroll down in this view to see trends across breath tests, meals, symptoms, stool, sleep, and stress.

Using the List view
The List view is especially useful, as it shows all entries for a selected day in one place, including:
- Breath tests
- Meals
- Symptoms
- Sleep
- Stool
- Stress
- Medications
- Notes
You can scroll through this list to review or edit entries.
How to Edit or Delete Entries
To edit or update a meal (for example, changing the time or adding a missing ingredient):
- Go to Home > Trends > List
- Find the meal in the list
- Tap the entry you want to change
- Use the pencil icon to edit
- Use the bin icon to delete
To delete other entries (such as breath tests or symptoms):
- Go to Home > Trends > List
- Tap the bin icon at the top right of the List view (located just below the graph)
- Select the entries you want to remove
Tip: If you can't find a meal you logged earlier, make sure you are in the List view and have scrolled to the correct date.
