# COSI Science vs RoadReady Ohio

The clearest difference is rating: RoadReady Ohio at 4.7 against COSI Science's 4.0. RoadReady Ohio also leads on ratings volume (1.6K vs 28) and update cadence (every 3 weeks vs every 2 months). COSI Science's advantage is review sentiment (64% vs 27%) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

RoadReady Ohio holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: RoadReady Ohio has 1.6K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 64% of COSI Science's written reviews are positive against 27% of RoadReady Ohio's, so the app with the better star average is not the one people write more warmly about.

COSI Science ships an update every 2 months, RoadReady Ohio every 3 weeks. The most recent releases landed on November 2, 2026 and November 8, 2026 respectively.
