# Stenfit vs ONE running

The clearest difference is rating: ONE running at 4.8 against Stenfit's 4.0. ONE running also leads on ratings volume (26 vs 5) and iOS requirement (15.6 vs 17.0). Stenfit's advantage is in-app purchases (none vs 3) and review sentiment (100% vs 75%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. ONE running sells 3 in-app purchases, starting at $14.99 per month. Stenfit asks for nothing beyond the download.

ONE running holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: ONE running has 26 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 75% of ONE running'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, ONE running weekly. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
