Screen Ruler supports centimeters and inches, magnifier-assisted alignment, and haptic feedback. Measure Small Objects on Your Screen Use Screen Ruler for stationery, frames, craft materials, and other small objects that fit along your device screen. Place the object directly on the screen, move the measurement marks to its edges, and read the length. Core Features • Calibratable ruler: Match the scale to an object of known length and save calibration for your device. • CM and inch scales: Switch between centimeters and inches for everyday measurements. • Magnifier assist: Align measurement marks with object edges more confidently. • Haptic feedback: Feel subtle feedback while adjusting the marks. How to Get More Reliable Results For best results, place the object directly on the screen and check the scale against a known length. Calibrate the ruler if you notice an offset. Accuracy and Limitations Screen Ruler is designed for short, everyday measurements. Accuracy depends on device calibration, screen placement, and how precisely the marks are aligned. It does not use the camera or AR and is not intended for measuring rooms or large objects. Feedback: ankek1er@gmail.com
