Keep track of the progress of your Buddhist practices.
** If it hangs when you start practice - uncheck (or move slider to right) "Dim at night time" in settings **
Meditation tracker comes with predefined preliminary practices group(Ngondro) and you can of course add your own practices and plan a schedule based on date you aim to complete practice or number of daily repetitions. Each session is stored for possible later use.
Now with the sync/backup. The app will automatically export its data to the SD card once a week when you enter the main screen. There's an option to trigger export and import in settings.
This application is not teaching you anything. It's just a humble counter. If you want to learn Buddhist meditation - better find yourself a teacher. Check if he or she shows qualities you'd like to achieve and ask for the teachings.
