Features

One phone is all the gear you need

No counter, no wristband, no rope sensor. Open the app, stand the phone up, jump.

Get jumping

No accessories needed — your iPhone is the counter and the coach.

Core check-in

Stand the phone up and jump

Place the iPhone 1.5–2.5m away. Step into the frame and start jumping. The AI counts. Works in regular indoor light, with everyday clothes — counts stay steady.

Each jump counted as it happens — no need to hold a counter
30 / 60 / 90 / 120-second timed runs, or free-form
Jump as long as you like with adjustable durations
Camera frames are wiped right after counting — never archived, never uploaded

6 training modes

Don't know how to train? The app does.

Six built-in training rhythms, beginner to advanced, each set to a beat-based BGM. Just follow the rhythm — no stopwatch, no counting rounds.

Sprint: 30 seconds, all-out, chase your max count
Tabata: 20s on + 10s off × 8 rounds — the classic hard protocol
HIIT: 30s on + 15s off × 6 rounds — a cardio storm
Pyramid: 30→60→90→60→30 seconds, climb up then down
Stair: 1 / 2 / 3-minute levels, push the ceiling
Endurance: hold a steady cadence for the long haul

Want to design your own routine? Pro lets you set rounds, durations, and rest periods however you like.

Freestyle

Beyond the basic bounce — tricks count too

Pick a move and start. While counting every jump, the AI checks whether each one was that move, then shows clean reps and everything else side by side. "20 jumping jacks" for PE homework? You'll know the moment you stop.

Jumping Jack: free, the easiest place to start
Single-leg (left / right), High Knees, Alternate Step: Pro
Freestyle sessions count toward today's check-in and total jumps, without touching your basic-bounce record
4 freestyle badges: First Freestyle, Jack Master, All-Round Freestyler, Textbook Form

See it add up

Every jump leaves a trace: badges, videos, score cards, goal progress.

58 badges

Turn every milestone into a reward worth seeing

Jump more, jump longer, finish a new mode — badges unlock automatically. Each one comes with its own little celebration animation that makes the moment land.

Streak — 9 badges (7-day, 30-day, 100-day streaks…)
Performance — 10 badges (first 50-streak, hit a cadence target, no breaks, first goal hit…)
Training — 22 badges (a ladder for each of the six modes + 4 freestyle badges)
Lifetime — 5 badges (10K, 50K, 100K total jumps…)
Special — 4 badges, plus Challenge — 8 badges (first challenge created, Rule Maker…)

58 badges in total. The collection itself becomes a reason to come back.

Highlight video · score card

The video is ready before they catch their breath

The session is recorded automatically with score, streak, cadence, and training mode baked into the frame. Tap save and it's in your photo library — drop it in any chat without editing.

Score and brand watermark baked into the video — the count is right there when you share it
Plus a 1080×1080 score card, perfect for a single-image post
9 score-card templates: Classic is free, plus 8 Pro designs — Spring Festival / Summer Vacation / School Sports Day / Starry Night / Mid-Autumn / Children's Day / Morandi / Black & Gold
Both video and card are rendered on-device — nothing is uploaded

Fitness goals

How many in one minute? Set a goal and find out

Set a one-minute jump-rope goal for yourself or your family, and see your level — and how far you are from your goal — the moment a session ends. Basic goal evaluation is free.

Primary-school ages can pick the built-in reference standard; everyone else sets a fully custom target count
Progress everywhere: score-card level badge, weekly / monthly summaries, Home Screen widget
Dedicated goal achievements — badges for your first goal hit and for hitting it day after day
Advanced (Pro): goal progress chart and multiple goals

Based on China's National Student Physical Fitness Standard (2014 revision), for reference only — always follow what your school or local education authority publishes.

Jump together

Jumping alone is easy to quit. Having someone to beat is not.

Friend challenge

Drop a code in any chat — they'll come jump too

After your run you get a 6-character invite code, a QR, and a nice composite image. Send it. They scan or type the code, jump too, and both scores land on a single VS card. Five ways to play:

Timed jumps: 15 / 30 / 60 seconds — most jumps wins (free to create)
Cadence PK: compare jumps per minute — rhythm over brute force
Training PK: both run the same training mode, highest total wins
Endurance: a multi-day check-in duel — who shows up every day?
Custom challenge: you set the jump time, rest time and rounds; they jump the exact same plan

Creating a challenge: timed jumps are free, the other types are Pro. Joining a challenge is always free — anyone with a code can compete. Also:

No friends yet? AI Sparring will warm you up — sometimes it lets you win
Codes expire after 48 hours so old codes don't get re-used by mistake
No global leaderboard — only invite holders see the result; no videos or photos uploaded, just the score numbers

Siblings on one phone? Sorted.

Each kid gets their own profile — separate records, achievements, and reminders. 2 profiles in the free version, up to 5 in Pro.

Switch language anytime

Each profile picks its own language — Simplified Chinese, Traditional Chinese, or English — independent of the system setting. Handy for bilingual learning at home.

Records follow you across devices (Pro)

Sign in to the same iCloud account and your records, achievements, and profiles sync between iPhone and iPad. New device, no setup.

Everyday comfort

Check your progress without opening the app — day or night.

Widgets · Free

Know if you've jumped today — without opening the app

Put a widget on your Home or Lock Screen and your check-in progress is right there the moment the screen lights up, one tap from a session. Completely free.

Small and medium Home Screen sizes: streak, today's jumps, weekly progress, and how far to your goal
Rectangular and circular Lock Screen widgets: today's check-in status at a glance
Tap to go straight in — start a check-in, or land on the home screen
Adapts to Dark Mode and follows your in-app language

Lock Screen widgets require iOS 16 or later.

Dark Mode · Theme colors

Make the app look the way you like

Dark Mode is completely free: follow the system automatically, or lock Light / Dark under Settings → Appearance. Everything is adapted — from the launch screen and app icon (iOS 18 dark / tinted variants) to every page inside the app.

5 theme colors: Sky Blue is the free default; Forest Green / Violet / Coral Pink / Ocean Teal are Pro
Appearance and theme color are saved per member, so everyone keeps their own
Score cards, weekly / monthly reports and other share assets keep their fixed palette, so exports always look consistent

Streak Shields: miss a day, keep the streak

Sick day, exam week, a trip? The next time you open the app, it asks whether to spend a shield to bridge yesterday. A shield protects the streak count only — it never adds a check-in: the calendar and stats stay honest, and parent reports note "incl. N shielded". 1 a month on the free plan, 3 with Pro, and they can't be chained back to back.

Syncs to Apple Health · free

Turn it on in Settings → More and every session is saved to the Health app as a Jump Rope workout, alongside the rest of your activity. Off by default. Because Health belongs to the device owner, it can be turned on for one member per device — a child's jumps never end up in a parent's health data.
