The most common reason your fiber count shows as 0 on the home screen - even after logging meals - is that Balloon is set to read fiber data from Apple Health instead of calculating it from the meals you log in the app. When Apple Health is the data source but isn't actually sending fiber data, the count stays at zero.
How to fix it
Tap the profile icon in the top left of the screen
Go to Connected Apps
Select Apple Health
Under "Fiber data source", make sure the Apple Health toggle is turned OFF
Once it's off, Balloon will use the fiber estimates from the meals you log directly in the app, and your daily fiber count should update correctly.
Still showing 0?
In rare cases, there can be a brief syncing delay - especially if you log two meals back to back very quickly. If toggling the Apple Health setting doesn't fix the issue:
Close and reopen the app
If it still shows 0, reach out to our support team with a screenshot and we'll investigate further
