# doodlio vs COSI Science

The clearest difference is review sentiment: COSI Science at 64% against doodlio's 17%. COSI Science also leads on iOS requirement (11.0 vs 15.6). doodlio's advantage is rating (4.6 vs 4.0) and ratings volume (199 vs 28). On price, update cadence, ads and in-app purchases there is nothing between them.

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

doodlio holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: doodlio has 199 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 17% of doodlio's written reviews are positive against 64% of COSI Science'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 2 months. Both last shipped on November 2, 2026.
