## Review summary

Users praise the app for its broad Sudoku variety and features, plus iPad optimization and relaxing focus benefits. However, stability issues are widespread: frequent freezes/crashes, loss of current games and progress after updates, and compatibility problems on older devices or iOS. Bug reporting is poorly supported, with in-app reports often not working and few clear channels to contact developers. Overall, strong puzzle variety and tools are offset by reliability and support concerns.

### Pros

- Multiple difficulty levels and puzzle types keep the game engaging.
- Helpful features like daily reminders and bonus games.
- iPad-optimized with an intuitive interface.
- Relaxing and focus-friendly experience for Sudoku fans.

### Cons

- Frequent freezes and crashes that disrupt gameplay and can cause loss of a current game.
- Progress and best times can be lost after updates or crashes.
- Compatibility issues on older devices (e.g., iPad 2) or certain iOS versions.
- Bug reporting is limited or hard to access; in-app reporting may not work and contact options are unclear.
