I can’t hear the voice
- Open GeoNum → Settings → Check English Voice.
- On iPhone or iPad, turn silent mode off and raise the media volume.
- Make sure an English system voice is installed on the device.
- Every text-based exercise remains available if speech is unavailable.
Using GeoNum in airplane mode
Lessons, generated questions, and progress storage work locally. Before a flight, use Check English Voice, then switch on airplane mode and test spoken practice once. Voice availability alone does not prove that a system voice has been fully downloaded for offline use.
Reminder troubleshooting
GeoNum reminders are optional local notifications, not alarm-clock alarms. Allow notifications, select the reminder days and time, then use Send a Test in 5 Seconds. Power-saving and system notification settings can still delay or suppress a reminder.
Resetting local data
- Reset Learning Data removes attempts, progress, and saved sessions.
- Delete Practice & Report Data also removes saved content reports.
- A content report stays on the device unless you deliberately share it through the system share sheet.
