Poop Log
Feels weird to suggest this but I’ve been using this app for a while because of some GI issues. It would be interesting to see if the data correlates to anything else. I know the data in the app can be exported to csv but I’m not sure if it’s accessible otherwise, it might just be saved to the local device.
