FAQ#
Q: After the CEFR level test, the difficulty feels off. What can I do?
A: The initial test is a quick vocabulary-based assessment and may not perfectly match your actual level. You can manually adjust the difficulty in Settings, or retake the test. After using the app for a while, it will automatically adapt based on your answer history.
Q: What model does the AI conversation feature need? How large is it?
A: Based on your device’s performance, the app recommends an appropriate model (Llama 3.2 or Qwen 2.5). Model size is approximately 1–4 GB. After downloading, conversations work completely offline — no internet required.
Q: AI conversation responses are very slow or frozen?
A: On-device AI inference speed depends on your device’s performance. Older iPhones will be noticeably slower. Try selecting a smaller model in Settings.
Q: The generated articles are too difficult to understand?
A: Articles are generated based on your CEFR level. If they feel too hard, lower your level setting in Settings, or manually select a lower difficulty when generating articles.
Q: Will my study records and saved vocabulary be backed up?
A: All data is currently stored locally on your device only. iCloud backup is not supported. Uninstalling the app will erase all records.
Troubleshooting#
- AI model fails to load: Ensure at least 3 GB of free storage, and check that the download wasn’t interrupted
- App crashes during AI conversation: Try switching to a smaller model in Settings
- Force quit and relaunch the app
- Check iOS version ≥ 17.0
