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. [ Presets ] • Save your favorite times as presets so you can start in a tap • Add, delete, and reorder presets freely • All presets sync to your Apple Watch automatically [ Premium (one-time purchase, not a subscription) ] • Unlocks 5 premium voices • Apple Watch integration — start and control timers right from your wrist • Start straight from a Home Screen or Lock Screen widget — one tap, without opening the app • Custom voice interval — choose exactly how often the count is read • Extended workout stats • Unlimited goals & season widget — set a goal on every preset and see your season score and tier right on your Home Screen • iCloud backup & restore — presets, records, goals, and settings are saved automatically and restored on a new device • Removes in-app ads [ Made for you if ] • You train in rounds — HIIT, Tabata, circuits, boxing, or CrossFit • You can't or don't want to look at the screen mid-workout • You train static holds — planks, dead hangs, pull-ups • You need time awareness during yoga, meditation, or breath work • You want a one-tap workout timer from your Apple Watch [ Privacy & permissions ] • Tracking permission is only requested for personalized ads (declining doesn't affect any app feature) • No microphone, contacts, location, camera, or health data access Support: contact@pocketlabs.kr Privacy policy: https://pocketlabs.kr/listentimer-privacy/en

About

Jolt

Features
Read full description

Jolt is an interval timer for functional-fitness athletes that talks, so you never have to look at your phone mid-workout. It counts you in, calls every round and rep target out loud in a real recorded voice, warns you when rest is nearly over, and calls "Time!" at the finish. Put the phone on the floor and train. BUILD ANY WORKOUT • EMOM and flexible rounds — stack blocks with different reps and timing. Rounds 1–2 at 8 reps, rounds 3–4 at 7, round 5 for max: that's three blocks, not three workouts. • AMRAP with a time cap • For Time, counting up, with an optional cap • Tabata and any custom work/rest interval WRITE THE ACTUAL WORKOUT Add the movements to each block — 12 wall balls, 9 burpees, 6 squat cleans — from a built-in library of 100 movements across barbell, dumbbell and kettlebell, gymnastics, bodyweight, machines and odd objects. Or type your own. Repeating a block? Copy its movements to the next one in a tap. REAL COACH VOICES Seven recorded coach voices, bundled with the app. No robotic text-to-speech, no download, and no internet required. Your music keeps playing underneath and ducks only while the coach speaks. BUILT FOR THE GYM FLOOR • Big-screen mode — mirror to a TV for the whole class, with the clock, the movements and the time remaining • Live Activity on the lock screen and Dynamic Island • Keeps timing and talking with the screen locked or in another app • Total time remaining shown in digits as well as on the ring • Countdown beeps and haptics, so it works muted too SHARE A WORKOUT Send any workout as plain readable text anyone can do — plus a link that recreates it exactly in someone else's Jolt, movements and all. Or show a QR code. Sharing is free in both directions, forever. NO NONSENSE No ads. No account. No tracking. Jolt collects nothing at all — there is no analytics of any kind, and every workout stays on your device. JOLT PRO Free includes one block per workout, all four workout types, one full-quality coach voice, and workout sharing in both directions. Jolt Pro unlocks: • Unlimited blocks per workout • All seven coach voices • Workout history • Big-screen TV mode • Halfway call-outs Pro is available monthly or yearly, or as a one-time purchase if you'd rather never see a subscription again. The yearly plan starts with a 7-day free trial. Questions or ideas: mazkopolo@icloud.com Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
