FAQ
Do I need an account?
No. Jigu Japanese has no accounts. Lessons and audio are built into the app and work offline. Your progress is stored on your device.
What is free?
Every lesson is free to take in order: finish a lesson and the next one in that chapter opens. Jigu Pro lets you jump to any lesson. If your membership ends, the lessons you completed and your reviews stay available.
How do I restore a purchase?
Sign in with the Apple Account you bought with, then tap Restore purchases on the membership screen or in Settings.
How do I cancel a subscription?
Deleting the app does not cancel a subscription. Manage or cancel it in iPhone Settings → Apple Account → Subscriptions, at least 24 hours before the current period ends. Refunds are handled by Apple at reportaproblem.apple.com.
Can I change the teaching language?
Yes. Explanations are available in English, Simplified Chinese, Traditional Chinese, Korean and Thai. Switch any time in Settings; your progress is kept.
How do I add a widget?
Touch and hold an empty area of the Home Screen → tap + → search for Jigu Japanese, then pick Word of the Day or the streak widget. Lock Screen widgets are added while customizing the Lock Screen.
Is the audio recorded by native speakers?
The Japanese audio is AI-generated speech, and every clip is checked against its script. If you hear a mistake, email us the lesson and the word.
