Tempo Boxing

Turn any song into a boxing workout. Tempo Boxing watches your punches through the front camera and spawns targets on the beat of whatever music you're already playing — your Spotify queue, a YouTube mix, the gym's overhead speakers, a friend's Bluetooth speaker, a live DJ set, a rehearsal room full of drums. No playlist integration, no pairing, no setup. If you can hear it, the app can sync to it. HOW IT WORKS Prop up your phone. Start the music. Throw hands. The front camera tracks your fists in real time using Apple's Vision framework. The microphone listens for the beat. Targets appear on screen in rhythm — kick drums, snares, hooks — and your job is to punch them before they fade. Combos stack. Missed beats cost you. Your heart rate does the rest. FOUR WAYS TO TRAIN Punching Only — No music, no pressure. Freeform drills and warm-ups. Targets appear one at a time; punch when you're ready. Beat Workout — The main event. Play anything on any speaker and the app syncs targets to every beat it hears. Works with Spotify, Apple Music, YouTube, SoundCloud, the radio, a live DJ — literally anything audible. Beat Workout 2x — Same live-mic setup, but targets land on the beat AND between beats. Double density, double intensity. You'll gas out faster than you think. Your Own Song — Import a track and the app pre-analyzes it once, choreographing a perfect target map to that exact song. Same track, same workout, every time. Perfect for repeat drills with your favorite hype music. WHY IT'S DIFFERENT • Works with any music source — no login, no pairing, no integrations needed • Runs 100% on-device — camera frames and mic audio never leave your phone • No accounts, no ads, no subscriptions, no paywalls • No equipment — no wraps, no bag, no wearables, no Apple Watch required • Private by design — nothing is recorded, uploaded, or shared WHO IT'S FOR Fighters looking for a quick cardio round between sets. Runners who need a rainy-day alternative. Office workers who need to punch something at 6pm. Anyone who's ever shadowboxed to a good song and wished the song would punch back. Put your phone down. Stand six feet away. Hit play.
