I use a health monitoring app and wristband called Fitbit. While I use the device mainly for health concerns, one feature that I really like for mental health hygiene is the vibration alarm. You can set the alarm to go off at any time, and it’ll silently alert you using a quiet and peaceful vibration.
I used the alarm function to remind me to take pills, change activities, perform tasks, go to meetings, etc.
