Justjump rope.

It counts. Your iPhone camera reads every rep in real time — no wearable, no setup, no games. Prop it up and go.

02 — SEQUENCE

How it
works

Four beats, one continuous take. No taps mid-set — the rope, your hand, and the camera do the talking.

01

Prop up your phone

Lean it against anything at chest height and step into frame. That's the whole setup.

NO TRIPOD REQUIRED
02

Wave to start

Raise a hand and the counter arms itself. No screen tap, no fumbling — just get moving.

HANDS FREE
03

Jump

Every full rope rotation counts. Miss a catch? It waits and resumes — your total never resets.

ON-DEVICE VISION
04

Wave to finish

Wave again, or tap the button. Your jumps, catches, and time are sitting right there, waiting.

TOTAL, INSTANTLY

03 — THE VIEWFINDER

What you
see

The camera view stays live and unretouched the whole set. Jumps, catches, and time sit over the frame — nothing else competes for your attention.

  • Full-screen camera view, no clutter, no distractions.
  • Jumps, catches, and time update in real time, every rep.
  • Works in portrait or landscape, indoors or on a rooftop.

04 — PRIVACY

Nothing
leaves
the phone

Every frame is processed on the Neural Engine, right there in your hand, and discarded the instant it's counted.

No accounts, no tracking, no data collected — just jump.

  • No accounts. Open the app and start jumping — there's nothing to sign up for.
  • No cloud. Video never leaves your device; it's analyzed frame by frame and discarded.
  • No tracking. We don't collect analytics on your sessions, your body, or your location.
  • No wearable. Just your phone's camera and Apple's on-device Neural Engine.

06 — FAQ

Questions,
answered

The short version of everything you'd want to ask before your first set.

No. Any rope you already own works fine, and there's nothing to wear or pair. The camera and on-device vision do all the work — you just jump.

Yes, fully. Everything runs on-device using the iPhone's Neural Engine, so it works offline in a basement gym, on a rooftop, or anywhere else the signal doesn't reach.

The app tracks full rope rotations, not just motion — so a wobble or a half-swing won't inflate your count. If you miss a catch mid-set, it holds and resumes instead of losing your total.

Jump rope is what it's built and tuned for, and it's what we'd point you to today. It counts landings rather than rope passes, so ropeless moves — jump-in-place, high knees, tuck jumps, jump lunges — often register too. They aren't tuned yet, though, and a long set can end early. Proper ropeless support is in progress for a future release.

Never. Frames are processed in real time on your device and discarded immediately. Nothing is recorded, saved, or sent anywhere — there's no server to send it to.
