# DRVN vs COSI Science

The clearest difference is rating: DRVN at 5.0 against COSI Science's 4.0. DRVN also leads on review sentiment (100% vs 64%). COSI Science's advantage is ratings volume (28 vs 3) and update cadence (every 2 months vs every 4 months). 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.

DRVN holds the better App Store score, 5.0 against 4.0.
