PeakTimer

PeakTimer is a customizable interval timer for any timed workout or training session — HIIT, strength, running, cycling, boxing, yoga, mobility, climbing, breathwork, and anything else built around timed segments. Build it once, use it everywhere — your routines sync across all your devices. Build routines from your own intervals. Each routine plays through a sequence you design — work, rest, hang, stretch, anything you name — across sets and rounds, with optional prepare and cooldown phases. Audible beeps count down the last three seconds of every interval so you can keep your eyes off the screen. — TAILOR EVERY ROUTINE • Name your intervals — "Work", "Hold", "Hang", "Stretch", whatever fits • Pick colors that read at a glance during a set • Set strength targets in kilograms, pounds, or as a percentage of your max • Configure prepare, rest between rounds, rest between sets, and cooldown independently • Group routines into collections (Hangboarding, HIIT, Mobility…) — STAY FOCUSED MID-WORKOUT • Big countdown that reads from across the room • Color-tinted phase background tells you at a glance what you're doing • Preview row shows what's next so you can mentally prepare • Round / set / interval pip counters for at-a-glance progress • Pause, skip, or restart any phase with one tap • Optional screen wake-lock so the screen stays on during the workout — HANGBOARDING & STRENGTH WITH A TINDEQ PROGRESSOR (optional) • Pair a Tindeq Progressor wirelessly over Bluetooth for live force readings • Real-time chart shows your pull through every interval against your targets • Calibrate your max strength once, then set per-interval targets as a percentage — SYNC ACROSS DEVICES (optional) • Anonymous by default — your routines stay on your device • Sign in with Apple or Google to sync routines across all your devices • Delete your account and all your data from inside the app at any time Built for runners, climbers, lifters, yogis, and anyone who wants their interval timer to do exactly what they tell it to.
