A jump rope counter for iPhone and iPad
No fluff. Just jump.
Prop up your phone and jump. The camera counts on the phone, so you stop counting and stay in rhythm.
It counts, so you don't have to.
Counting in your head is how you lose count. One catch, one stray thought, and you are guessing. The camera keeps the number for you, on your phone with nothing tracked. You just jump.
- JumpsThe camera watches you, not the rope. Each takeoff and landing is one jump.
- TimeStarts when the countdown ends, stops when you tap End.
- CatchesTrip on the rope and it notes a catch. The count keeps going.
Jump in. Jump out. Done.
Prop it up.
Lean it against anything at chest height and step back.
Wave to start.
Raise a hand and hold it there, or tap Start. A short countdown, then it counts.
Jump.
Your music keeps playing. The count runs over the camera view.
Tap End.
Jumps, time, catches. Put the phone down.
Built to be closed, not opened.
A lot of fitness apps want you to stay longer: games, stats, streaks, a feed. Your attention is what they are after.
JustJump Rope is built for the opposite. Open it, jump, tap End, and go live your day. It does one job, then leaves you alone: no streaks to keep alive, no feed, no ads.
Your video never leaves your phone.
Each camera frame is read on the device to find your jump, then discarded. Nothing is recorded, saved, or uploaded. No analytics, no ads, no tracking.

Is my video ever stored or uploaded?
Never. Frames are read on your phone and discarded. Nothing is recorded, and there is no server of ours to send it to.
