Easy. Powerful. Effective.

Im telling everyone about this app. Regular pocket biofeedback devices are pricey, plus you need to carry an additional device. This app, however allow you the same convenience for an affordable price. My daughter was advised to do biofeedback to help combat her migraines. The portabliity of this app allows her to integrate it into her busy lifestyle. My one suggestion would be to add relaxing background music options. But I simply play some before I open the app. Extremely useful app!
