I had entered 12 days of info religiously until the app auto-updated. Since then it crashes on start up. There doesn’t seem to be a way to report problems on the website so I sent messages via Twitter.

It doesn’t crash in airplane mode but does as soon as I turn airplane mode off.



This app is for a scientific study and the info it will provide far out weighs any of its bugs.

Great idea, but bad app!


I like the idea of this app and want to contribute to Dr Panda studies. But this app has too many bugs that it is hard to believe in any collected data concistency.
To be fixed:
Slow on iPhone 5s
It takes up to 1min to get camera ready
Losing your data on saving
Loosing pictures on saving
Freezes frequently
Freezes when wifi and lte enabled
Quits by itself with data not saved
