# ACT ® Math Prep vs Khan Academy

The clearest difference is in-app purchases: Khan Academy at none against ACT ® Math Prep's 1. Khan Academy also leads on update cadence (every 6 weeks vs every 8 months) and ratings volume (110K vs 138). ACT ® Math Prep's advantage is rating (4.8 vs 4.6) and iOS requirement (13.0 vs 15.0). On price, review sentiment, ads and device support there is nothing between them.

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

ACT ® Math Prep holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 138, so its average is the more settled of the two. Written reviews complicate that: 67% of ACT ® Math Prep's written reviews are positive against 74% of Khan Academy's, so the app with the better star average is not the one people write more warmly about.

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