Shift - Interval Timer Workout

Start your HIIT workout in 3 taps. No setup friction. No clutter. Just a clean, fast interval timer built for people who actually train. Shift is a purpose-built HIIT timer designed for speed. Set your work intervals, rest periods, and rounds — then go. No account required. No ads. No bloated feature set. WHAT SHIFT DOES: — Custom interval configuration: work time, rest time, rounds, sets — Tabata, EMOM, and custom HIIT protocols — Clear audio cues and haptic feedback so you never miss a transition — Visual countdown optimized for glanceability mid-workout — Minimal UI that stays out of your way BUILT FOR: — Home workouts with no equipment — Gym training between sets — CrossFit-style timed circuits — Tabata protocols — Any interval-based training WHY SHIFT: Most timer apps are either too simple (just a stopwatch) or too complex (10 screens before you start). Shift sits in the sweet spot — fully configurable but fast to start. Designed by Credes, a product studio that ships tools people actually use. Start training. Not configuring.
