Hi,
I'm currently using the Android app (4.4.3 from the playstore - which strangely seems not to be offered here on the page) and since the last update, it is no longer working. After a while, the app doesn't react anymore (widgets frozen, opening the app doesn't do anything, however the "Smart Add" still works). It seems that the main app is not executed, as it doesn't show in my taskmanager.
The only way to bring the app back is to clear all data via Android settings -> app -> Doit.im -> delete data.
This is no real workaround for me, as the frozen app occurs several times a day, and all widgets need to be recreated after deleting the data. Sometimes it works for some hours, sometimes it stops after 5 minutes.
I'm using a Wiko phone with Android 4.2.2.

Best regards
