Three pro-grade tools, one app. Measure any room in seconds with AR. Size small objects on your screen. Hang things perfectly level. Stop juggling tools - start today.
RulerKit replaces three apps with one beautifully built measurement toolkit - AR Ruler, Screen Ruler, and Spirit Level. Designed for real-world accuracy, built for everyday use.
▸ AR RULER - point and measure
Aim your camera at any object and see the exact distance instantly. Tap to place a start point, move, and tap again. That's it. Powered by ARKit and LiDAR (where available) for millimeter-level precision on supported iPhones and iPads.
• Measure rooms, walls, furniture, windows and doors
• Capture the height of buildings, trees and people
• Switch between cm, inches, meters or feet with one tap
• Save every measurement to your gallery with a photo
• Export and share dimensioned screenshots
▸ SCREEN RULER — measure anything you can place on screen
Lay a small object directly on your iPhone screen and read its size in real time. Calibrate once with a credit card, coin or any item you know — accuracy holds for life.
