# Khan Academy vs ACT Prep

The clearest difference is in-app purchases: Khan Academy at none against ACT Prep's 3. Khan Academy also leads on update cadence (every 6 weeks vs every 8 months) and ratings volume (110K vs 50). ACT Prep's advantage is iOS requirement (13.0 vs 15.0). On price, rating, ads and device support there is nothing between them.

Both are free to download. ACT Prep sells 3 in-app purchases, starting at $4.99 per 7 days. Khan Academy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Khan Academy against 4.7 for ACT Prep. That said, the two scores are not equally well evidenced: Khan Academy has 110K ratings behind it against 50, so its average is the more settled of the two.

Khan Academy ships an update every 6 weeks, ACT Prep every 8 months. The most recent releases landed on September 24, 2026 and August 26, 2026 respectively.
