# Stenfit vs My Jump Lab

The clearest difference is rating: My Jump Lab at 4.6 against Stenfit's 4.0. My Jump Lab also leads on ratings volume (254 vs 5) and iOS requirement (15.0 vs 17.0). Stenfit's advantage is review sentiment (100% vs 59%) and in-app purchases (none vs 3). On price, ads and device support there is nothing between them.

Both are free to download. My Jump Lab sells 3 in-app purchases, starting at $5.99 per month. Stenfit asks for nothing beyond the download.

My Jump Lab holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: My Jump Lab has 254 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Stenfit's written reviews are positive against 59% of My Jump Lab's, so the app with the better star average is not the one people write more warmly about.

Stenfit ships an update every 9 days, My Jump Lab every 3 weeks. Both last shipped on October 29, 2026.
