FeetHandAR

Feet Hand AR turns a familiar sizing trick into a simple camera tool. Place an open hand in view and the app estimates useful hand dimensions. The free app shows wrist-to-middle-fingertip hand length and individual finger lengths in inches or centimeters.

Advanced Measurements is a one-time $1.99 unlock for thumb-to-pinky tip span and knuckle width, useful for glove sizing, grip fit, and quick hand-fit checks.

On compatible devices, the app uses back-camera ARKit/LiDAR depth by default for the best available real-world estimates. LiDAR depth is included in the free app. On front cameras and non-depth devices, measurements scale from your known hand-length calibration.

Hand Measure is built for quick sizing checks when you do not have a ruler nearby. It is not a certified measuring device or medical tool.
