Log the rope. Own the PR.
Run the interval timer, log what you actually did, and let Jumpy handle the rest — weekly volume, streaks, eleven kinds of personal best, and a card the moment you beat one. It works with the rope already in your bag, because it never had to count for you.

The rope is cheap. Everything around it is not.
Serious rope training is intervals, unbroken sets and slow numbers going up. Almost nothing tracks that. The counting ropes want you on their rope and their battery; the fitness apps see a rope session as a grey blob of "other cardio"; and the rest of us end up with a note called "jumps" and a spreadsheet nobody opens twice.
None of that fails because the counting is hard. It fails because nothing keeps the one number you actually care about — the best unbroken set — and hands it back to you when you beat it.
A set takes four taps and no decisions
The log is built for the thirty seconds between rounds, when you are out of breath and holding a phone. Jump type and count are the only required fields; duration, effort and a note are there if you want them and never block finishing a session.
- Jump type and count are required; duration, effort and a note are not
- Recent jump types float to the top and the keypad opens numeric
- Save and add another, so sets chain without a trip back to the previous screen
What the app does with it
Everything past the log exists to make the next session happen: what you did this week, what your best has been, and what is worth showing someone.
A timer that already knows your intervals
with 30/30, 45/15 and 60/30 ready to go, rounds counted for you, and an open timer for when you just want to jump.
Records per jump type
so max unbroken double-unders is its own record and a run of singles never quietly beats it.
Streaks that do not punish
with a compact calendar where a day still in progress never counts as missed.
Cards that make themselves
the moment you break something: display-size number, jump type and date, exported as a PNG for the camera roll.
Four screens, one loop
Train is where the session happens. Log is what it became. Records is the wall of bests. Cards is the part your friends see.
Everything you need to keep showing up
Every feature exists to make logging faster, a PR heavier, or sharing more tempting. Anything that does none of those waits.
Interval timer
30/30, 45/15 and 60/30 presets, rounds and rest counted, plus a plain open timer.
Session and set logging
Jump type, count, optional duration, effort rating, and notes that never block finishing.
Eleven personal bests
Longest session, best 1, 5 and 10-minute counts, max unbroken sets, and first tricks.
Streaks and consistency
A compact calendar, current and longest streak, and sessions per week without the drama.
Volume and rope time
Jumps and minutes by week and month, average per session, and a split by session type.
Card export
PNG in square, story and portrait-feed sizes, to the camera roll or straight to a share sheet.
How a session goes
Start the timer
Pick a preset — 30s on / 30s off, 45s / 15s, a minute on / thirty off — or leave it as an open timer and just jump. Rounds and rest are counted for you while the rope is moving.
Log the sets as you go
Between rounds, tap in the jump type and the count. Double-unders, singles, crossovers, freestyle, weighted — the type is what makes the PR mean something later.
Finish and get the summary
Total jumps, sets, best unbroken set, and time on the rope. Jumpy compares that against every session before it and tells you what you just broke.
Share the card, or do not
A new best generates a card automatically — big number, jump type, date, no app branding shouting over it. Post it or keep it. The streak counts either way.
Against a rope that counts for you
Who it is for
People chasing double-unders
The unbroken set is the whole sport for a while. Jumpy tracks max unbroken as its own record per jump type, so the jump from 40 to 104 is a thing that happened on a date, not a vague feeling.
CrossFit and conditioning athletes
You already do intervals. This is the timer plus the log in one place, so a rope session stops disappearing into "other cardio" in an app that never understood it.
Freestyle jumpers
First clean side swing cross is a milestone that no counter will ever register. It gets logged as a first, and firsts get cards.
Anyone logging in Notes right now
If your training history is a note called "jumps" or a spreadsheet you stopped opening, this is that, with the maths and the streak done for you.
Your log is a file on your phone
No account, no feed, no leaderboard you did not ask to be on.
- Sessions, sets and personal bests are stored in a local database on the device. There is no sign-up step and nothing to sync before you can log your first set.
- Cards are rendered and exported on the phone. Sharing one is you sending an image, not the app publishing on your behalf.
- There is no social graph and no public profile. Jumpy is a training log that happens to make good screenshots, not a network.
Free to log. One payment for the rest.
The core loop — timer, sessions, streaks, personal bests — is the free product, not a trial of one. Pro is a single payment, because a training log you rent is a training log you lose.

Straight answers
The things people ask before they decide a manual log is worth the taps.
Does Jumpy count my jumps automatically?+
No, and that is the design. Automatic counting needs either their rope or your phone strapped to you, and it still cannot tell a double-under from a single or a clean set from a trip. You type the number, which takes about four seconds, and in exchange every rope works and every count is honest.
Do I need a special rope or any hardware?+
None. Speed rope, beaded, PVC, licorice, a weighted rope, the one that came free with a gym membership — you can save each as a profile and log against it, but you never have to pick a rope before logging.
What counts as a personal best?+
Eleven things, tracked separately: longest session, most jumps in a day, most jumps in one session, best 1, 5 and 10-minute count, longest streak, most sessions in a week, max unbroken double-unders, max unbroken singles, and first tricks. Bests are per jump type, so a double-under record is never beaten by a single.
What is a PR card?+
The image Jumpy builds when you break a record: the number at display size, the jump type, the date, and a thin line of branding. Square, story and portrait-feed sizes, exported as a PNG to your camera roll or straight into a share sheet.
What is free and what is Pro?+
Logging, the interval timer, streaks and personal bests are free — the core loop is not the paid part. Pro adds unlimited history, advanced stats, custom jump types, extra card styles, CSV export, milestone alerts and multiple rope profiles, as one payment rather than a subscription.
When can I actually get it?+
It is in development. The training journal, interval timer, records and card export all work today — the screenshots on this page are the running app, not mockups. App Store and Google Play links land here when the builds are through review.
Any rope. Full control.
Jumpy is being built now: the timer, the journal, the records wall and the cards are running. The store links land on this page the day they exist.
