## Review summary

Reviewers praise Chessimo 2.0 for its excellent, extensive tactical content and the spaced-repetition approach that many say accelerates chess improvement. However, repeated themes across reviews highlight a heavy bug burden in 2.0, including freezes, crashes, and UI quirks. Account/purchase issues and data-migration problems further frustrate users. The core learning tool is valued, but stability, reliability, and better account management are needed for broad user satisfaction.

### Pros

- Extensive, high-quality tactic puzzle content that many users call unmatched and highly valuable for learning.
- Spaced repetition training builds tactical memory and skills (board vision, calculation, precision, speed).
- Progressive difficulty (easy-to-hard units) and structure support steady, measurable improvement.
- Perceived value for serious players, with reports of noticeable improvement and recommendations.

### Cons

- Frequent bugs and instability in Chessimo 2.0 (crashes, freezes, and window/piece glitches).
- Account and purchase problems: inability to restore purchases, login/sync failures, missing content after upgrade, and poor support.
- UI/UX issues harming training experience (board scrolling on iPad, small/obscured boards on iPhone, overlays that hide pieces).
- Migration pain from 1.0 to 2.0: progress/content not transferring and some features removed.
