About
Angle Measurer turns any photo into something you can measure. Drop three points and you get the angle, the other side, and how far the line bends, all updating live as you drag.
PRECISE PLACEMENT
• A magnifier appears while you drag, so every point lands exactly where you want it
• Pinch to zoom up to 10x, double-tap to fit
• See-through points so you can see what's underneath
TWO WAYS TO MEASURE AN ANGLE
• 3-point angle: drag A, B and C to measure the angle at B, the other side, and the bend
• Two-line angle: draw two separate lines and measure the angle where they would meet
• Add extra arms (A′ and C′) to compare against an existing line
• Put as many angles on one photo as you need
MEASURING TOOLS
• Inclination: how far an edge is from square to a reference line
• Tilt: the same, with a direction (+ or −)
• Distance: the gap between two points, in millimeters
• Offset: how far one point sits past another along a reference line
• Scale: set real-world size from anything of known length
STRAIGHTEN PHOTOS
Took a photo of a screen at a slant? Drag the four corners onto the screen and Angle Measurer flattens it, so your angles come out true instead of stretched.
