# SAT Math Test Prep vs Khan Academy

The clearest difference is in-app purchases: Khan Academy at none against SAT Math Test Prep's 1. Khan Academy also leads on update cadence (every 6 weeks vs every 12 months) and ratings volume (110K vs 144). SAT Math Test Prep's advantage is iOS requirement (13.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. SAT Math Test Prep sells 1 in-app purchase, starting at $9.99 per month. Khan Academy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for SAT Math Test Prep against 4.6 for Khan Academy. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 144, so its average is the more settled of the two. Written reviews are what separate them: 79% of SAT Math Test Prep's written reviews are positive against 74% of Khan Academy's.

SAT Math Test Prep ships an update every 12 months, Khan Academy every 6 weeks. The most recent releases landed on September 8, 2026 and September 25, 2026 respectively.
