## Review summary

Overall sentiment is positive about core gameplay and features like auto notes, privacy, themes, offline use, and a one-time price. Major downsides are paywalls for settings, inconsistent difficulty, problematic hints, no resume for unfinished games, and some UI/UX quirks. Users also request teaching hints and better progress export. The app shows active development and strong customization, but pricing and balance concerns temper enthusiasm.

### Pros

- Auto notes/pencil marks (pre-filled notes) streamline solving
- Privacy/ad-free with no data collection
- Theming and customization options including dark mode
- One-time price / no ongoing subscription
- Works offline

### Cons

- Settings and features locked behind paywall or paid upgrades
- Inconsistent or overly hard difficulty balance across levels and updates
- Hints are too intrusive/limited in usefulness and can auto-fill
- No save/resume of unfinished games (no history for unsolved games)
- UI/UX issues such as hard-to-see borders or tap-target precision and some modes being restricted/free
