Got my Propilot today and I found the device to be well built. This review is strictly for the app. The app is useless. When registering, there is no USA in the country drop down menu. As the other reviewer mentioned, you can not scroll between screens. There is no way to end a workout on the screen and move off that screen other than to exiting the app. The chin touch on the push-ups screen doesn’t work if you have a beard, so use your nose. Disappointed.
