# ChiMarathon vs RunSync!

The clearest difference is update cadence: ChiMarathon at every 2 weeks against RunSync!'s every 4 months. RunSync!'s advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

RunSync! holds the better App Store score, 3.7 against 3.5. Both are backed by a comparable volume of ratings — 4 and 6 respectively. Written reviews complicate that: 33% of ChiMarathon's written reviews are positive against 25% of RunSync!'s, so the app with the better star average is not the one people write more warmly about.

ChiMarathon ships an update every 2 weeks, RunSync! every 4 months. The most recent releases landed on October 16, 2026 and October 6, 2026 respectively.
