Train by the clock, not against it. Feint is a round and interval timer for people who actually train β€” fighters, lifters, runners β€” built to be reliable, customizable, and equally at home on your iPhone and Apple Watch. Randomize your interval lengths to maximize output and effort β€” no more easing off as you get close to the end of a round. WHY FEINT β€’ Timing you can trust β€” the timer is anchored to the wall clock, so it stays accurate even when your phone locks or backgrounds. It never drifts, and your rounds end exactly when they should. β€’ Tackle psychology β€” intervals can be randomized so you don't start easing off knowing you're nearing the end of a round. Maximum effort from beginning to end. β€’ It lives on your wrist β€” independent Apple Watch companion, not a mirror. It runs your workout with a haptic cue for every transition and counts as a real workout toward your activity rings. β€’ Controls without unlocking β€” a Live Activity puts a running countdown and a play/pause control on your Lock Screen and in the Dynamic Island. β€’ Workouts built your way β€” compose sessions from labeled phases, each with its own color, duration, and audio cue. Choose a fixed number of rounds, a target duration, or a continuous session. Add a "Get Ready" countdown, tune the beep tone and waveform, and set a backdrop per profile. β€’ Audio you can hear over your music β€” crisp synthesized cues that can duck your music or podcast just enough to be heard, and keep firing while the screen is off. β€’ See your progress β€” a streak calendar and weekly-volume charts turn finished sessions into momentum, including the ones you ran on the watch. β€’ Yours, and private β€” everything stays on your device. No accounts, no tracking, nothing collected. Share a profile with a training partner as a simple file whenever you want. BUILT FOR Boxing and kickboxing rounds Β· BJJ and grappling rolls Β· HIIT and Tabata circuits Β· running and rowing intervals Β· HEMA / sword drills Β· and anyone who trains in timed rounds. PRICING Try every built-in workout for free. A one-time unlock β€” Feint Pro, no subscription β€” opens up custom profiles and the Apple Watch app.
