## Review summary

Review consensus: The Protractor app is praised for its simplicity and speed: you can take a photo, draw measurement lines, and get angle values without a physical protractor. Users value the ability to overlay the protractor on an image, upload quickly, and use it in various contexts (games, therapy, photography). However, multiple reviews raise usability concerns: no zoom or focusing on the image, overlays that obstruct the center and are not translucent, and occasional orientation-related inaccuracies or inverted readings across device orientations. These issues limit precision in some situations and are the main drawbacks.

### Pros

- Very easy to use and quick to get angle measurements.
- Take a photo and mark lines on the image to measure the angle.
- No physical protractor needed; the overlay provides precise angles.
- Works well across different images and use cases (games, therapy, photography).
- Simple upload and measurement process.

### Cons

- No zooming/focusing on the background image limits precision.
- Overlay markers obstruct the view and are not translucent enough.
- Angle readings can be inconsistent or inverted depending on device orientation.
