Read full descriptionHide full description
FlexibleARuler is an AR ruler for measuring distances, angles, paths, and a curvature index with your iPhone or iPad camera. Aim the center reticle at a surface, then add points or trace a path. FOUR MEASUREMENT MODES ⢠Distance: add a start and end point to measure the distance between them. ⢠Angle: add a start point, corner, and end point to measure an angle. ⢠Path: trace a surface to measure the length of a path. ⢠Curvature: trace a curve on the starting plane to calculate a dimensionless curvature index. Triangle guides help show how the result relates to the curve. The index is the triangle height divided by the start-to-end distance, multiplied by 100. SAVE AND SHARE RESULTS Review saved measurements in History. Save a result image to Photos or share it, with a value label connected to the measured area and a result card below the image. Retake an endpoint to update a measurement. Existing history stays available when you change the app language or display units. MEASUREMENT TOOLS ⢠Meters, centimeters, and inches ⢠A 3à magnified guide for distance and angle measurements ⢠Surface detection and contextual hints ⢠Haptic and sound feedback ⢠A light and optional plane and feature-point guides ⢠A quick guide and measurement tips Available in Japanese and English. One-time app purchase, with no subscriptions, in-app purchases, or advertising. No account is required. Measurement history is stored on your device. Requires an ARKit-compatible iPhone or iPad with iOS / iPadOS 18.2 or later. Measurements are estimates affected by lighting, surface material, and device movement. The stability indicator does not guarantee accuracy. Support: misterdevelop.support@gmail.com https://misterpepo.github.io/misterdevelop-support/
