Verdict
The clearest difference is ratings volume: Endorphins Running at 909 against RunKASI's 7. Endorphins Running also leads on update cadence (every 2 weeks vs every 5 weeks). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. RunKASI sells 2 in-app purchases, starting at $59.99 per 6 months and Endorphins Running sells 4 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for RunKASI against 4.9 for Endorphins Running. That said, the two scores are not equally well evidenced: Endorphins Running has 909 ratings behind it against 7, so its average is the more settled of the two. Written reviews are what separate them: 100% of RunKASI's written reviews are positive against 99% of Endorphins Running's.
RunKASI ships an update every 5 weeks, Endorphins Running every 2 weeks. The most recent releases landed on October 21, 2026 and October 22, 2026 respectively.
