## Review summary

Overall, users like the simple UX and motivational earned-time rewards, but recurring issues hold back satisfaction: localization problems, crashes and permissions concerns, Android feature gaps (focus option, customization, cross-device sync), and negative-time counting bugs.

### Pros

- User-friendly interface with no mandatory account.
- Motivational rewards system that ties to real apps.
- Appealing concept of balancing earned time with actual usage.

### Cons

- Language localization issues: Chinese text or foreign language displays, causing confusion.
- Stability and privacy concerns: frequent crashes and a large number of permission requests.
- Missing Android features and parity with iOS: no focus option on Android, limited customization of limits, and no cross-device sync.
- Negative screen time counting bugs: reports of negative time and inconsistent counts.
