# Radio Ball 3D vs Cosmo Run

The clearest difference is rating: Cosmo Run at 4.6 against Radio Ball 3D's 4.1. Cosmo Run also leads on ratings volume (49 vs 11). Radio Ball 3D's advantage is review sentiment (88% vs 67%) and iOS requirement (12.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Radio Ball 3D sells 1 one-off in-app purchase and Cosmo Run sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Cosmo Run holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 11 and 49 respectively. Written reviews complicate that: 88% of Radio Ball 3D's written reviews are positive against 67% of Cosmo Run's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 6 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
