### 1/5 — Pay money

*2026-04-27*

I only used the app for 2 mins and it says so have to pay, is it blocked forever till I pay it or do I have a timer for each day??

### 1/5 — 垃圾

*2025-12-16*

### 1/5 — Duh?

*2025-12-16*

Nice but it would’ve been more helpful if the people were informed you have to pay $$ to access the technology in this, jumping jacks, format!! I have apps where it cost .99 to access additional technology but itmt the app is still functional and works. The access isn’t blocked bc of funding.

### 4/5 — It was good until…

*2025-11-18*

### 3/5 — 不准的

*2025-10-18*

跳着跳着就不计了，根本不准

### 1/5 — JumJac joke

*2024-12-20*

Download the app for Apple Watch and when I open the app it tells me to upgrade to Pro to use the watch app.  Pretty much worthless at that point.  Should be zero stars

### 5/5 — 不错的开合跳

*2024-11-12*

试用了一下，不错，计数挺准

### 3/5 — 500下目标，结果跳了640下，灵敏度已经调到最大20了

*2024-08-19*

500下目标，结果跳了640下，灵敏度已经调到最大20了，请尽快改进

### 5/5 — 超级好用！减肥好伙伴

*2024-07-18*
