## Review summary

Reviewers praise the app for broad format support and offline TTS, but reliability is a major concern due to frequent crashes and data loss. Monetization and ads plus separate paid features frustrate users, as does the learning curve and limited support. UI/UX issues, especially around dark mode, further impact experience. Overall, it offers strong format versatility and offline reading, but stability, usability, and pricing drawbacks limit its appeal.

### Pros

- Reads a wide range of formats (mobi, azw, azw3, prc, epub), enabling versatile reading.
- Offline text-to-speech (voice reading) works.
- Generally capable for reading different documents; several reviewers say it works well or is great for reading various formats.

### Cons

- Frequent crashes and stability problems (crashes on tapping, data loss, Dropbox-related crashes).
- Aggressive monetization with ads in the free version and multiple separate charges for features (dark background, extra formats, pro version).
- Difficult to learn and poor support (hard to use, lack of helpful guidance, nonfunctional support form).
- UI/UX and dark mode inconsistencies (app UI not aligning with iOS dark mode; bright menus).
