ReachOut Breathe is a great intuitive app, that measures heart rate through your phone’s camera and the controlled breathing is easy to follow. The combination of biofeedback with the controlled breathing that can be personalised makes this a very powerful app for highlighting anxiety reactions. With only two functions in this app you can’t get lost looking for where to find breathing help in the app like I do in several of the anxiety apps. Recommended for over 12 years of age. Add this one to your apps if you ever have to teach controlled breathing or work with young people with anxiety. Only available for Apple products at the moment.
