Breathing Trainer's support info

 Breathing Trainer is a simple app.

The only setting you can apply is changing the color mode of the app: light, dark or system.

Main screen of the app allows you to choose between different pre-programmed breating programs.

If you want to add a new one, click on customisation screen and add button (to remove added one - swipe left).

You need to provide a name of the program, specify how may phases you want and set each phase: decide if it needs to be inhale, exhale or hold and now long should it last.
