HandMaxx, the hand-optimization app

Field notes

The proposed workflow turns a single photograph of the back of a hand into five marker scores, then assigns habits according to the weakest areas. The homepage specifies a two-to-five-minute daily routine and a 21-day comparison cycle, with premium access covering the individual scores, protocol, and progress tracking. It also states that image analysis is handled by OpenAI, while scans are discarded and user data remains on the iPhone; the app is described as coming soon to the App Store.
