Finally, a way to notice what's really bothering your kid.
Log meals, symptoms, and stools in seconds. BellyMystery finds the patterns in your own data that are worth discussing with your pediatrician.
Launching soon on iOS and Android
Before the pattern, there's just a hunch.
You've cut out the strawberries, then the dairy, then put them back. Some nights are fine. Some nights aren't, and there's no thread to pull, just a worried kid and a guess. BellyMystery doesn't diagnose anything. It just remembers what you can't, so the next flare-up has evidence behind it instead of another guess.

Talk to your pediatrician

Built for busy households
Seconds, not minutes
