# iSmoothRun vs 10W2S

The clearest difference is price: 10W2S at Free against iSmoothRun's $4.99. 10W2S also leads on update cadence (fortnightly vs every 2 months) and review sentiment (85% vs 70%). iSmoothRun's advantage is ratings volume (943 vs 16) and rating (4.4 vs 4.1). On ads, in-app purchases, monetization model and device support there is nothing between them.

10W2S is free to download; iSmoothRun costs $4.99 up front. iSmoothRun sells 2 in-app purchases, starting at $4.99 per month and 10W2S sells 3 in-app purchases, starting at $2.49 per 7 days. Whichever you choose, the download price is not the number that matters.

iSmoothRun holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: iSmoothRun has 943 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 70% of iSmoothRun's written reviews are positive against 85% of 10W2S's, so the app with the better star average is not the one people write more warmly about.

iSmoothRun ships an update every 2 months, 10W2S fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
