# Unit Circle Practice vs Calculus

The clearest difference is rating: Unit Circle Practice at 4.8 against Calculus's 3.5. Unit Circle Practice also leads on review sentiment (75% vs 33%) and update cadence (every 6 months vs every 16 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Unit Circle Practice sells 1 one-off in-app purchase and Calculus sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Unit Circle Practice holds the better App Store score, 4.8 against 3.5.
