## Review summary

Reviewers largely value the app for basic viewing of ODT/ODP/PDF documents, with several praising its simplicity and usefulness. However, the main drawbacks are ad-supported usage requiring a subscription to remove ads, a read-only editing limitation (no writing or copying), and frequent file-opening issues for certain formats. Performance is inconsistent, particularly online. Overall, it's seen as a solid viewer with room for improvement in editing, performance, and ad/permission handling.

### Pros

- Generally good for viewing and handling office documents.
- Reliable support for opening ODT/ODP/PDF files.
- Positive overall reception and strong user satisfaction across multiple reviews.

### Cons

- Ads and a subscription to remove them.
- Read-only mode; cannot edit or copy text.
- Not opening some files (ODT/ODP/PDF) and other formats.
- Slow and inconsistent performance, especially online.
