Discover your hand size, span, and proportions with camera-guided measurements. Measure feet and everyday objects, compare hand ratios, or take a playful break with finger games. HAND MEASURE Place an open hand in view to see hand length, thumb-to-pinky span, and colored measurement guides. Switch between inches and centimeters. Tap to freeze the view, or hold steady for automatic capture. Explore individual finger lengths, thumb-to-index span, knuckle width, and palm length. Show or hide measurement lines to focus on what interests you. DEPTH WHEN AVAILABLE Supported front cameras use TrueDepth, and supported back cameras use LiDAR. When usable depth is unavailable, measurements use a hand-length reference. Adjust that reference using a physical ruler for a more personalized scale. EXPLORE HAND PROPORTIONS Size is only part of the picture. Ratio mode compares knuckle width, palm length, and hand span with hand length. Compare straight wrist-to-fingertip distances with wrist-to-middle-fingertip distance, shown as 1.00. Compact colored bars make proportions easy to understand. Thumb, index, and ring ratios are included without an upgrade. CUSTOM MEASURE: FEET AND MORE Place two points to measure a distance. Tap directly on the camera view, or aim the center crosshair and tap Add point. Adjust endpoints, delete individual lines, and switch between inches, centimeters, and ratios. In ratio mode, the first line becomes your reference. For feet, measure heel to toe, then add a width measurement. Open the shoe-size calculator to explore estimates and a size chart. Always check the specific brand’s sizing guidance before buying shoes. TAKE A PLAY BREAK • Finger Treadmill: walk your fingers across the screen, track distance and pace, and review your run history. • Thumb Pinky Switch: alternate thumb and pinky poses with both hands. • Tip Spark: reach numbered targets with the matching fingertip—or your wrist. • Palm Compass: flip and rotate your hand to match the cue. • Lotus Garden: spread your fingers to bring a garden into bloom. • Lotus Breathing: unfold a lotus with optional breathing guidance. Additional activities include two-hand pose matching, rising pose challenges, hand-controlled music, and arcade games. OPTIONAL LIFETIME ADVANCED Hand length, thumb-to-pinky span, selected ratios, and several activities are included without an upgrade. A one-time Lifetime Advanced purchase unlocks additional measurements, proportions, selected games, and advanced treadmill features. No subscription. Purchase details are shown in the app. 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, ratios, and shoe sizes are estimates—not certified ruler readings, medical measurements, or professional fitting advice. Results depend on lighting, camera angle, pose, tracking quality, reference accuracy, and device capabilities. Hand span changes with finger spread. Use a physical ruler when precision matters. Depth and AR features require compatible hardware. Camera activities need visible hand landmarks and do not assess health, strength, mobility, or dexterity. Keep movements comfortable and never force a pose.
