Measure. Play. Explore. Discover your hand’s dimensions and proportions, turn your screen into a ruler, and keep your measurements in one place. Then take a playful break with finger games and hand-controlled activities. HAND MEASURE Show an open hand to the camera to explore hand length, finger lengths, palm dimensions, and thumb-to-finger spans. Colored guides show what each measurement represents. Choose inches or centimeters, hide guides you don’t need, and tap to freeze the view—or hold steady for automatic capture. Explore an estimated glove size based on palm width, then check the glove maker’s sizing chart. Ratio mode puts size in perspective. Compare palm dimensions and span with hand length, or compare wrist-to-fingertip distances against the middle fingertip as your reference. SCREEN RULER Measure small objects beside your screen with horizontal and vertical scales. Show inches, centimeters, or both, and drag optional guides to mark an object’s edges. Use the credit card reference to check the scale and calibrate when needed. The reference includes standard card dimensions and typical thickness for a handy everyday comparison. MEASURE NOTES Keep measurements you’ll want to find again—from a person’s hand size to a doorway, shelf, or piece of furniture. Add a name and write measurements in any format. Search, edit, delete, or share your notes. No fixed measurement fields or required units. CUSTOM MEASURE Place two points in the camera view to estimate a distance. Tap to place points, or aim the center crosshair and add them. Adjust endpoints, remove individual lines, and switch between inches, centimeters, and ratios. In ratio mode, your first line becomes the reference. Measuring feet? Add heel-to-toe and width measurements, then explore estimated shoe sizes. Always compare results with the specific brand’s sizing chart. PLAY WITH YOUR HANDS • Touch and Go: bring the requested fingertips together, then gently move them apart.

PRIVACY Camera images are processed on your device and are not uploaded. You choose whether to capture and share measurement results. IMPORTANT TO KNOW Measurements, glove sizes, and shoe sizes are estimates—not medical measurements or professional fitting advice. Accuracy depends on lighting, camera angle, hand position, tracking quality, calibration, and device capabilities. Compatible cameras can use TrueDepth or LiDAR. When usable depth is unavailable, hand measurements rely on a confirmed hand-length reference. Check Screen Ruler’s scale with a physical reference before relying on it. Use a physical ruler when precision matters. Hand activities do not assess or treat health conditions. Keep movements comfortable, skip difficult combinations, and never force a pose.
