# Ohio State vs COSI Science

The clearest difference is update cadence: Ohio State at every 5 days against COSI Science's every 2 months. Ohio State also leads on rating (4.5 vs 4.1) and ratings volume (778 vs 27). COSI Science's advantage is review sentiment (64% vs 52%) and iOS requirement (11.0 vs 18.0). 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.

Ohio State holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: Ohio State has 778 ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 52% of Ohio State'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.

Ohio State ships an update every 5 days, COSI Science every 2 months. The most recent releases landed on September 24, 2026 and August 9, 2026 respectively.
