## Review summary

Reviews praise the app for readability and ease of use, especially for visually impaired users, with many calling it among the best. The major drawback across multiple reviews is intrusive advertising: long, frequent ads, and ads that continue even when users pay for premium.

### Pros

- Easy to use with a clean, well-designed UI
- Significantly improves readability through large font sizes (including 2x)
- Helpful for people with weak eyesight and those needing bigger text
- Positive overall sentiment with many calling it one of the best apps for font size

### Cons

- Ads are pervasive and intrusive (long ads)
- Too many ads overall
- Ads persist even after purchasing premium (premium does not remove ads)
