JustJump Rope vs Skip Lab
Both apps count jump rope using the phone camera, and neither needs a special rope or a watch. The real difference is what happens to the video, and what you pay for that.
| JustJump Rope | Skip Lab | |
|---|---|---|
| What it counts with | The phone camera, on the device | The phone camera |
| What it keeps | Nothing. Frames are read and discarded, and there is no server of ours | It films your sets so you can watch them back |
| Account needed | No account, no sign-in | No account |
| Price | Free to download, 7 days free, then $5.99 a month or $39.99 a year | Free |
| Privacy label | Data Not Collected | Usage Data, not linked to you |
Which one is for you
Skip Lab is free and films your sets, which is the right trade if you want to watch your form back afterwards. That video has to live somewhere, and its privacy label lists usage data.
JustJump stores nothing at all. No video, no account, nothing leaves the phone, and the App Store privacy label reads Data Not Collected. If you want the count and nothing else, that is the cheaper kind of simple, and it is what you are paying for.
If you want footage of your sets, take Skip Lab. If you want a number you can trust and no trail behind it, take this one.
