About
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.
