Work. Rest. Repeat — and hear every second of it. Set your intervals, then keep your eyes on your form. ListenTimer reads each second out loud through the whole round, so you always know where you are without looking. Planks, dead hangs, stretches, and breath work all work the same way. [ What it does ] • Per-second voice countdown • Routines (Tabata) — work and rest alternate automatically, with a spoken cue at every phase change • Start instantly with one tap from your Apple Watch complication • Plays nicely with your music and podcasts — audio ducking dips the music just for the count, then brings it right back • Background playback — the count keeps running even when your screen is locked • Live Activity — see the count on your Lock Screen • Haptic feedback — your wrist taps along, even when your ears are covered • Monthly calendar stats — see which days you trained at a glance • Weekly goals & seasons — set a weekly goal on a preset, and your completions build up to a tier over a 3-month season [ Voice characters ] • Default Female (free) — a calm, clear default voice • Default Male (free) — a natural, steady male voice • Yoga Instructor (premium) — a gentle, peaceful yoga instructor • Drill Sergeant (premium) — a forceful voice that pushes your limits • The Reaper (premium) — a chilling voice that counts down time • News Anchor (premium) — a precise, straightforward news voice • Late-night DJ (premium) — a soothing late-night radio voice Each character brings a different tone to your training rhythm.
