# Radio Ball 3D vs Doodle Sub

The clearest difference is rating: Doodle Sub at 4.6 against Radio Ball 3D's 4.1. Doodle Sub also leads on ads (none vs shown) and iOS requirement (7.0 vs 12.0). On price, review sentiment, ratings volume and update cadence there is nothing between them.

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

Doodle Sub holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 11 and 5 respectively. Written reviews complicate that: 88% of Radio Ball 3D's written reviews are positive against 86% of Doodle Sub's, so the app with the better star average is not the one people write more warmly about.

Radio Ball 3D ships an update every 6 weeks, Doodle Sub every 4 weeks. Both last shipped on October 23, 2026.
