Hi Mary Ann,
The app adjusts to the settings of your device. So please make sure that your phone/tablet is set to English and the app will switch automatically.
The Coach will calculate your personal plan based on your goals, progress and weekly ratings whenever you tap the orange "Start Coach week" button in the fating main menu.
thanks for your request. You can abort your current fasting week in the fasting-tab (after scrolling down a little bit). Afterwards you can choose 5-2. Happy BodyFasting!
