The application features a statistics section where you can view your past meditation activity. Metrics include amount of time spent and your overall statistics for a certain time period. It also is a good method to see how your meditation is evolving.
Insight Timer has some technical issues and the application won't close in the background in some cases. This causes your Android device to be quickly drained of its battery.
There's an in-app purchase of roughly $6 that will add an interval feature between bells, to let the user know how far they've progressed in a session.
Insight Timer is used by over half a million users in over 140 countries and features a world map, discussion groups and the ability to share your progress with friends.
When you're finished with a meditation session, the app allows you to write notes about that session. These notes are stored in a journal and can be exported.
The Zazen Medition Timer allows extensive options for interval programming within meditation sessions. For example, you can let a bell sound every three minutes or so.
Most of the audio in Meditation Music & Timer ++ is binaural, which results in a more realistic and natural listening experience. Binaural audio uses both ears to create a more immersive 360° sound. The sound quality itself is also very high.
The audio in the application only last 10 minutes each and doesn't loop, which means you'll have to manually restart the audio track in order to continue.
The interface in the Android app isn't optimal. There are some weird button placements, and UI-elements such as the buttons are rendered in a low resolution which results in a blurry interface on higher resolution devices.
