## Review summary

Overall mixed: a few users praise accuracy and educational value, but the majority complain about paywalls to see degrees, heavy ads and upgrade prompts, reliability issues (often not measuring correctly or only rad), a very short or non-existent free trial, and limited functionality (in-app camera only, no measurement from existing photos).

### Pros

- Accurate angle measurement when the app is functioning.
- Useful for beginners and amateur learners of geometry.
- Positive experiences from users when features work (really good stuff, awesome tool, excellent app for amateurs).

### Cons

- Must upgrade to see degrees; paywall blocks core functionality.
- Ads and upgrade prompts are persistent, even after attempting to pay for removal.
- Reliability issues: app often doesn't work, sometimes only rad measurements.
- Free trial is very short or effectively non-existent, making evaluation difficult.
- Limited functionality: usage restricted to in-app camera and rad-only measurements; cannot measure from existing photos; orientation and usability issues.
