Meditation Assistant helps you keep a regular meditation practice in your life. It provides a very simple interface with a number of customizable options. You can choose the type of meditation (timed or untimed), the duration, the start and end sounds, and the device behavior. It also has a monthly overview of your progress.

How does it work?

First, you need to create an account in the app. The app will then send you a verification code that you will need to enter in the app. Once you have done that, you will be able to log in and create your first session. The first session will be a timed session, with the duration and the start and end sounds. After that, you can create as many sessions as you want. Each session will have its own duration, start and end sounds, and device behavior. You can choose to share your progress online, if you want.
