About Edge Ruler – Scale & Slope
Try every feature free for 14 days. After that, the 1:1 ruler and calibration stay free; scales and slope are a one-time purchase. Not a subscription.
A ruler that starts at the end of your iPhone
Most ruler apps start their scale somewhere inside the screen, so you can't measure from the end of the phone. Edge Ruler treats the end of your iPhone (or case) as zero, so you can read door frames, trim and gaps straight off the edge.
Features
• 1:1 measuring in 0.5 mm steps, scales from 1:100 to 1:950
• Feet and inches with architectural scales from 1/16″ to 1″ = 1′
• Rulers on both sides in portrait and landscape, with a draggable reading line
• Slope in degrees, ratio (1/N) and percent to two decimals, locking automatically when steady
• One-minute calibration with a ruler or any credit card, per-case profiles, slope zero
• Open from the Lock Screen or Control Center (iOS 18 and later)
• English and Korean
Made for
Architects, designers and builders who read scales off drawings, and anyone checking ramps and drainage falls on site.
