A minimalistic note-taking app utilizing your phone's notification area:
- Take notes and save them as notifications
- Edit pinned notices
- Delete pins
- Hide notes for a specific period of time
The app was built with Material Design in mind.
All notes are stored in the app's database and survive reboots.
If your pins do not reappear directly after start-up, open the app because on some devices p!n may not be able to start in background. In this case try to enable 'Autostart' or disable some battery optimizations for this application.
A good resource for more information on this topic and solutions for various devices I have found here.
