Common questions
Do I need an internet connection?
Exercises work offline. You will need a connection to send a support email or open this page.
Where are results saved?
The app keeps the latest 20 completed attempts on your device, including repeats. It has no sync of its own between iPhone and iPad.
How do I add results to my calendar?
On the results screen, choose “Add to calendar”, complete device-owner authentication, choose a calendar and save the event. Nothing is exported automatically.
How can I delete my history?
Open “For parents”, complete system authentication and choose “Delete history”. A separate confirmation is required. Saved calendar events remain unchanged.
Why does the Parents section ask for Face ID or a passcode?
This is system device-owner authentication. The app never receives your passcode or biometric data. A child who knows the device passcode or has enrolled biometrics can also pass this check.
