impressive idea.
Here are my thoughts:
It would be great for an app that will silent in the background all apps by going into this app.
It stops everything except for this app.
You may ask but would not be easy to simply turn off your phone?
The idea is to remove distraction when you need time to focus. Eg meditate, creative endeavour, walk or nature time, etc. It counts how many hours you are off your screen (which tracks your screen time on/off).
Allows to schedule the hibernation of the app. So if you schedule to meditate at 7:00 then all apps except this one will be inaccessible including internet. Emergency dial is the only available and this app. It sends a reminder that in 1 min or 30 seconds the hibernation starts. User can choose to continue or not. If no response then it means to go on hibernation.
Make it difficult (two or 3 clicks) to disable the app when you started the hibernation (focus time) so it encourages people to carry on with the hibernation. It's a start and got more if you want โบ๏ธ hope that helps ๐ซ๐
