# Dynamic Runner vs RunKASI

The clearest difference is monetization model: RunKASI at free with in-app purchases against Dynamic Runner's subscription. RunKASI also leads on update cadence (every 5 weeks vs every 3 months). Dynamic Runner's advantage is ratings volume (361 vs 7) and iOS requirement (15.1 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Dynamic Runner sells 2 in-app purchases, starting at $9.99 per month and RunKASI sells 2 in-app purchases, starting at $59.99 per 6 months. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Dynamic Runner against 5.0 for RunKASI.
