Verdict

The call

The clearest difference is in-app purchases: Khan Academy at none against ACT Prep's 2. Khan Academy also leads on ratings volume (110K vs 207) and chart position (#67 vs unranked). ACT Prep's advantage is iOS requirement (13.0 vs 15.0). On price, rating, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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 207, so its average is the more settled of the two. Written reviews are what separate them: 74% of Khan Academy's written reviews are positive against 80% of ACT Prep's.

UpkeepUpdate frequency

Khan Academy ships an update every 6 weeks, ACT Prep every 3 months. The most recent releases landed on September 25, 2026 and September 15, 2026 respectively.
