# SAT Math vs Course Library

The clearest difference is in-app purchases: Course Library at none against SAT Math's 1. Course Library also leads on update cadence (monthly vs every 10 months) and rating (5.0 vs 4.8). SAT Math's advantage is ratings volume (5 vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. SAT Math sells 1 one-off in-app purchase. Course Library asks for nothing beyond the download.

Course Library holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: SAT Math has 5 ratings behind it against 1, so its average is the more settled of the two.

SAT Math ships an update every 10 months, Course Library monthly. The most recent releases landed on September 30, 2026 and October 1, 2026 respectively.
