Hand-volume measurement for armwrestlers, coaches and researchers. Using the iPhone's LiDAR sensor, 123Hand captures a hand, builds a 3D mesh on the device, and keeps every capture in your Files app. Nothing leaves your phone.
Requires an iPhone with LiDAR (Pro models from iPhone 12 Pro onward) running iOS 17 or later. Free, no account, no in-app purchases.
