# Course Hero vs Pre Calculus

The clearest difference is rating: Course Hero at 4.7 against Pre Calculus's 4.0. Course Hero also leads on review sentiment (28% vs 0%) and ratings volume (65K vs 4). Pre Calculus's advantage is iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Course Hero sells 11 in-app purchases, starting at $14.99 per month and Pre Calculus sells 8 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Course Hero holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Course Hero has 65K ratings behind it against 4, so its average is the more settled of the two.
