Some Android versions ask for permission to schedule exact alarms. It lets the app trigger alarms at precise times, even when the phone is in power-saving mode.
Steps
- When the dialog Enable Exact Alarms appears, tap Open Settings.
- Switch the permission on for Notification Tracker.
- Go back to the app.
If you tapped Skip
You can allow it later in Android Settings > Apps > Notification Tracker > Alarms & reminders.
