Protractor Angle Meter turns any photo into a precise workspace for measuring one angle or many. Frame an object in the live camera and freeze the image, or choose a photo from your library. Add as many angle measurements as you need to one photo. Change each measurement’s color and add an optional label so even complex checks remain easy to read. Use a shared pivot with two rays, or switch to four-point mode for two independent lines—even when their intersection lies outside the image. Drag any point while the Precision Loupe shows an enlarged crosshair above your finger. Pinch to zoom, pan the image, snap in 15° steps, and feel haptic feedback as you adjust. Measure interior, exterior, and reflex angles. View results in degrees, radians, or slope percentage. Every change saves automatically, so you can return to a measurement whenever you need it. With Premium Pass, export and share a clear JPEG containing the photo, colored measurement lines, arcs, values, and labels. Your saved source photo remains unchanged. No ads. Save up to 10 photo-based measurement records for free, with unlimited angle measurements inside every record. A one-time Premium Pass unlocks result-image sharing and unlimited records.
