Protractor is a simple and easy-to-use tool for measuring angles on images directly from your smartphone.

• Rotate, zoom, and pan images with intuitive gestures
• Display a semicircular protractor overlay for visual angle reference
• Ideal for checking tilt, slope, or measured angles in photos
• Supports camera images and gallery photos

Whether you're working on DIY projects, studying geometry, or reviewing motion in images, Protractor helps you measure angles quickly and accurately.

No registration, no internet connection, and no tracking — just practical functionality in your pocket.

Note: This app does not include a level or inclinometer function using accelerometers or gyroscopes.
It is designed for visual angle measurement by manually reading the scale overlaid on images.
