# Studdy vs Calculus

The clearest difference is review sentiment: Studdy at 89% against Calculus's 0%. Studdy also leads on rating (4.8 vs 2.0) and ratings volume (13K vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Studdy sells 8 in-app purchases, starting at $1.99 per 7 days and Calculus sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
