Set up pill schedules to trigger alarms/notifications when it is time to take your next pill.
Mark a pill as taken (or not-taken or not-sure or not-all) so you can review your pill-taking compliance stats afterwards. The mobile data retention period can be set up to be either 6 months or 12 months.
If you experience app notifications that don't trigger while your phone is sleeping/dozing/not in use for a long time: try switching off the 'Optimize battery usage' setting in the phone settings for the 'Pill Tracker and Reminder' app. This must be done after installing the app.
