## Review summary

Users praise the app for being free and providing a screen-darkening overlay, with some noting it can be touch-through and reasonably useful. However, many reports highlight that it does not offer true privacy (visibility from the sides), has device compatibility problems (especially on Samsung), includes ads/limited free features, lacks a quick-off toggle, and can be unreliable or intermittently stop working.

### Pros

- Free to use with no paywall
- Overlays and darkens the screen to obscure content
- Simple and lightweight to operate
- Allows interaction with underlying apps (touch-through) while the overlay is active
- Some users express positive sentiment like 'so far so good' or 'nice app' indicating perceived usefulness

### Cons

- Not a true privacy screen: content is visible from the sides and only partially covers the screen
- Incompatible with some devices (notably Samsung) and Android overlay constraints
- Ad-supported/free version with limited features and not convincing
- No quick way to disable it (no notification toggle) and cannot be easily turned off
- Reliability issues: overlay can cut out or stop working intermittently
