I can’t hear the voice
- Open Settings → Voice & repetition → 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.
Self-practice, not voice recording
Listen to the example and say it aloud. GeoNum does not record or play back your own voice, and does not automatically assess pronunciation. See → Say is self-assessed; Hear → Type checks the answer you type.
Reinstalling on a new device
GeoNum is a one-time, paid-upfront purchase with no subscriptions or in-app purchases. Use the same Apple Account in the App Store to find GeoNum in your purchased apps and redownload it without paying again, subject to device compatibility and App Store availability. There is no subscription to restore inside GeoNum.
Purchases and practice records are separate. GeoNum does not sync history across devices. Recovering records depends on your device backup and restore process; reinstalling alone does not restore them.
Resetting local data
Open Settings → Privacy & data for storage status and these confirmed deletion actions:
- RESET PRACTICE HISTORY removes attempts, progress, and saved sessions, keeping saved reports and app preferences.
- DELETE PRACTICE DATA & REPORTS also removes saved content reports, keeping app preferences and notification permission.
- A content report stays on the device unless you deliberately share it through the system share sheet.
To share a report, use Settings → Help & support → Saved content reports → EXPORT SAVED REPORTS. Reports are never sent automatically.
