A free app for Android, by AdiAppLab.
This app will help you get into the practice of meditation, and the Japa mala mantra.
It has a simple design, and the interface is easy to use. You can choose to use the timer, or the sound.
The timer is useful for when you are on a trip, or you have a lot of things to do, and you need to be able to concentrate. The sound is useful for when you are doing exercise, or if you have a lot of things to think about.
If you are new to meditation, you can choose to do it with the sound and the timer.
