## Review summary

Users praise the app for being simple and fast with useful geometry capabilities and helpful visuals. However, repeated issues include crashes, input-entry problems (clearing, inability to enter values, screen jumps), ads interfering with use, and lack of support for irrational numbers. Overall value is high for straightforward cases, but stability, input reliability, and non-integer support need improvement.

### Pros

- Simple to use
- Fast and quick results (up to 5 decimals)
- Useful for basic geometry and real-world tasks (work, exams)
- Visual triangle diagram updates with results
- Accurate calculations when inputs are valid

### Cons

- Crashes / instability / app stops working
- Input entry issues: cannot enter values; fields clear/erase; screen jumps
- Ads obscuring input fields and poor UI
- Lack of support for irrational numbers (only integers)
- NAN results and tiny buttons / overall poor UI when input is invalid
