## Review summary

Overall, reviews praise the app as easy to use and useful for angular/trig calculations, with several users noting precise results and value for learners or work tasks. However, repeated complaints focus on a steep subscription price (about $15/week), intrusive pop-up ads that disrupt use, and at least a few reports of the app not working or being unusable. Additional concerns include slow load times and a request for more decimal precision. In short, strong usability and accuracy are offset by monetization and ad experience that hurt everyday use.

### Pros

- Easy to use / user-friendly interface
- Useful for angular/trig calculations and learning
- Precise results / accuracy
- Helpful for work / quick calculations
- Generally reliable performance and positive usability

### Cons

- High subscription price (~$15 per week)
- Intrusive/ads-heavy experience (pop-ups and long ad sequences)
- Not working or unusable for some users at times
- Slow loading times / performance issues
- Reliability concerns due to広告 interruptions and onboarding friction
