CaliTimer: Handstand Timer

Record your handstands and CaliTimer times every hold for you, automatically. No stopwatch, no counting the seconds back from your footage. Prop your phone, hit record, and kick up. The moment you're in a handstand, CaliTimer starts timing the hold; the moment you break, it stops. Every hold is logged, every personal best is tracked. WHAT IT DOES • Detects when you're in a handstand using on-device pose estimation. • Times every hold from the instant you're stable to the moment you bail. • Logs every hold, grouped by date, with skill, duration, and personal best. • Tracks your personal best for each skill with the date you set it. • Optional target duration with an audio cue when you hit it. • Front and rear camera support. RECORD AND REVIEW, WITHOUT THE CLUTTER Watch your holds back to check your form during a session. Recordings are kept only temporarily, save the ones you want to your camera roll with a tap, and the rest are cleared automatically. Your training footage never quietly fills up your storage. UPLOAD MODE Already have footage on your camera roll? Import any handstand clip and CaliTimer runs the same detection on the video. Useful for catching up on past sessions or testing how the detection responds in different scenarios. PRIVACY-FIRST BY DESIGN • 100% on-device. The Vision framework runs the pose detection locally. • No accounts. No sign-ups. • No data leaves your phone ever. • No ads. No analytics. No tracking. • Works fully offline. WHAT'S NEXT Handstand is the first skill. Other calisthenics skills are on the roadmap including front lever, back lever, planche. CaliTimer is built and maintained by one developer.
