## Version history (last 5 releases)

### 1.8.0 — 2026-08-14

New: Freestyle Jump Rope
• Jumping jacks, single-leg hops, high knees and alternate-foot step — pick a move and go
• Every jump is judged in real time: correct reps count toward the move, the rest still count toward your total and daily check-in
• Jumping jacks are free for everyone; members unlock all moves automatically

Steadier counting when holding the phone
• We rebuilt how phone shake is handled: slight hand movement no longer swallows jumps — great for parents filming their kids
• You'll get a gentle hint to steady the phone if the camera shakes a lot; anti-false-count protection is unchanged

Fully adapted for iPad
• The interface now scales with your iPad's screen, from iPad mini to 12.9-inch
• Also fixed the cramped Home screen on smaller iPhones and the after-midnight stale data issue

### 1.7.2 — 2026-07-27

Fully adapted for iPad
• The interface now scales with your iPad's screen — larger text, easier-to-tap buttons, roomier cards
• Grids like Achievements, the calendar heatmap and template picker now fit more per row automatically
• Tuned per screen size, from iPad mini to 12.9-inch

 Home screen and detail fixes
• The Home screen is no longer cramped on smaller iPhones — content now scrolls
• Fixed the Home screen still showing yesterday's session after midnight
• The "Last session" card now opens the score card from its Share button, so the list scrolls smoothly
• Corrected how the date of your last session is described before you check in

Jump counting, challenges and subscription benefits are unchanged in this update.

### 1.7.1 — 2026-07-25

New: Fitness Goals
- Set a one-minute jump-rope goal for yourself or your family, and see your level and how far you are from your goal right after each session
- Use a built-in reference or set a fully custom target
- Progress everywhere: score-card badge, weekly / monthly summary, home widget, and new achievements
- Advanced (Pro): progress chart and multiple goals

A fresh, tidier Home screen
- A cleaner top bar puts today's check-in front and center
- "Streak" and "This week" are now combined into a single card
- A new Achievements shortcut — Training, Challenge, History and Achievements in one row
- Settings moved into the profile chip for one-tap access

Note: the built-in reference is for guidance only.

### 1.6.1 — 2026-07-21

• New Custom Challenge: you decide the jump time, rest time and number of rounds
• 4 ready-made templates, or import a custom workout you already saved
• Your friend takes on the exact same plan — highest total jumps wins
• New achievement: Rule Maker, unlocked by finishing a custom challenge
• Clearer before you accept: how to win, how ties break, when it expires
• Smoother scanning: a proper viewfinder plus a success indicator

### 1.5.2 — 2026-07-20

• Redeem codes right inside the app — no more jumping between apps
• Clearer membership status: subscriptions that won't renew now show an expiry date instead of a renewal date
• Fixed an issue where the expiry date could show too early when multiple entitlements overlapped
