### 5/5 — Accurate and Super Handy for Measuring Angles!

*2025-05-21*

This app is exactly what I needed—a simple yet powerful tool for measuring angles with my phone. The edge alignment feature works surprisingly well, and the app is very responsive and easy to control. Whether I'm doing woodworking, drawing, or just checking random objects around the house, this digital protractor gives quick and accurate results every time. It’s lightweight, cleanly designed, and extremely useful. Definitely deserves five stars!

### 5/5 — Ios

*2020-11-04*

Нормально, ничего лишнего. Замок с ключом в левом верхнем углу означает сделать фото - странное обозначение.

### 3/5 — Difficult to set desired angle

*2020-04-24*

This protractor app works, but is very difficult to set any desired angle with my finger or even a stylus. I wish it had some way to select incremental increases and decreases in the angle and settings for some common angles such as 30, 45, 60, and 90 degrees. Having said that, I found this protractor app because I found its matching ruler app first. The Ruler app is very accurate on my iPhone XR.  Thank you for an accurate ruler for my phone!
