Hand Measure: Size & Span

Get to know your hand dimensions with camera-guided measurement.

Measure hand length, explore detailed finger and span measurements with Lifetime Advanced, estimate shoe size, and enjoy three camera-based hand games.

HAND MEASUREMENT

Place one open hand in view and follow the camera guidance. See your estimated hand length on screen, hold steady for automatic capture, or freeze the view to inspect the result. Hand-length measurement is included without an upgrade.

CHOOSE THE RIGHT MEASUREMENT METHOD

Supported back cameras can use ARKit or LiDAR depth. Front cameras and cameras without supported depth use a hand-length reference that you measure and confirm. Unconfirmed measurements are clearly labeled as previews.

DETAILED HAND RESULTS

An optional one-time Lifetime Advanced purchase unlocks:

• Individual finger lengths
• Thumb-to-index span
• Thumb-to-pinky span
• Knuckle width
• Shareable hand and foot reports

USE INCHES OR CENTIMETERS

Choose the unit that works for you when reading and comparing measurements.

FOOT AND SHOE SIZING

Measure both feet with supported AR camera tools or enter ruler measurements manually. Supported devices prioritize LiDAR depth for assisted foot capture.

Compare foot length and width, then explore estimated:

• US and Canada men’s sizes
• US and Canada women’s sizes
• UK sizes
• EU sizes
• JP sizes

The app uses the longer confirmed foot when preparing final fit details. Always compare the estimate with the shoe manufacturer’s sizing chart.

PLAY WITH LIVE HAND TRACKING

Hand Play

Match 10 finger poses with finger-segment guidance and clear instructions showing whether your palm or the back of your hand should face the camera.

Shape Gate

A wall approaches through the live camera view. Form the requested hand pose, then move, resize, and rotate your hand to fit the opening before impact. Later levels add palm-direction challenges.

Rep Rush

Choose a timed hand exercise and complete as many full repetitions as possible. Exercises include:

• Open Palm & Fist
• Thumb Raise & Fold
• Finger Spread & Together
• Anatomical subtitle: Finger abduction and adduction

Rep Rush counts complete movement cycles and pauses the clock when hand tracking is lost.

PRIVACY

Camera images are processed on your device and are not saved or uploaded.

IMPORTANT TO KNOW

Measurements and shoe sizes are estimates, not precision instruments, medical measurements, or professional fitting advice. Results depend on calibration, lighting, camera position, hand placement, and device capabilities.

Check measurements with a physical ruler when precision matters. Consult the manufacturer’s sizing chart before buying shoes.

AR foot measurement requires a compatible device. Automatic depth-assisted foot-point placement requires supported LiDAR hardware. Manual foot measurements remain available.

The hand games recognize visible finger and palm positions. They do not assess health, mobility, strength, or dexterity. Keep every movement comfortable and never force a pose.
