AngleFinder: Protractor

Measure angles on screen, photos, and camera snapshots. Local-first, no account, no ads.

AngleFinder: Protractor helps you measure angles with a clean, local-first mobile workflow.

Use it as a digital protractor, place three draggable points over a photo, or capture a camera snapshot with an angle overlay. Export the result as a PNG, save it to your photo library, or share it with another app when you choose.

Key features: • Measure angles with three draggable points • Use a simple screen protractor for diagrams and sketches • Pick a local photo and measure over the image • Use the camera preview for real-world angle checks • Save or share a PNG measurement screenshot • No account, no ads, no tracking, and no required upload workflow

AngleFinder: Protractor is useful for quick geometry checks, DIY planning, classroom examples, diagrams, crafts, and everyday visual angle measurement.

Accuracy depends on how you position the points and the quality of the photo or camera view. For safety-critical, construction-code, medical, or legal measurements, verify with calibrated professional tools.
