habitual is a simple application to send reminders for things which are on a fixed, repeated schedule.

You can tell habitual which application to use using --exec. The default is notify-send. The application should take one argument – the name of the reminder. If you need to pass more, create a wrapper script and call that. The default is notify-send, but you may want to send to other services like Pushbullet or Pushover, for example.

Reminders are is typically stored at ~/.config/habitual/habitual, and are automatically reloaded when the file is changed. The format is like so:

cron|name

For example, here’s how someone’s reminders might look:

0 11-20 * * *|Drink water
0 1 * * *|Time to wind down
