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 and no required upload workflow • One clearly separated banner ad below the measurement controls Angle Finder 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.

Room scanning requires a LiDAR-equipped iPhone. Camera Level displays virtual guides; it does not project a laser. Magnetic Field is not a dependable wire or stud detector. Photo angles can be affected by perspective. Check critical measurements with appropriate physical tools. No account or advertising. Photos, scans and saved measurements stay on your device unless you choose to share them. Camera access supports camera and AR tools; optional location access supports true north.
