You can choose either manual or automatic option in the app’s settings (in the Profile thigle placed in the top right corner of the home screen – click Setting section – and choose the option for the calendar)
If it is manual, once you click Go for an event, an option Add to calendar will display. After you click this option, the event will be added to your phone’s calendar.
In the automatic option, once you click Go for an event – it will be automatically added to your phone’s calendar.
This way you will not miss any practice in your daily agenda:)
