User reviews

Users find Smart Protractor to be a simple, accurate, and versatile tool for measuring angles in woodworking, welding, and other projects. The app is appreciated for its user-friendly design and multiple modes. However, common issues include intrusive permission requests in the camera function, inability to auto-rotate the screen complicating use in some positions, lack of snapping to common angles or manual angle input, and introduction of full-screen ads after updates, which detract from usability.

Pros

Simple and user-friendly app that effectively measures angles.
Accurate and reliable for various uses such as woodworking, welding, and setting up tools.
Multiple modes available to suit different tasks including drawing and measurement.
Helpful for precise angle measurements without unnecessary clutter.

Cons

Camera function requires excessive permissions and enables many tracking cookies, raising privacy concerns.
Lack of screen auto-rotation makes it difficult to read and use in certain orientations.
Absence of features like snapping to common angles or manual input by degree makes fine adjustments fiddly.
Full-screen ads after updates annoy users and degrade experience.

uninstalled after first attempt to use the camera function, needs to many permissions and hundreds of cookies enabled to work, I gave up after turning off access to 120 tracking cookies and wasn't even a third of the way there.
