# Formula MAX vs Khan Academy

The clearest difference is price: Khan Academy at Free against Formula MAX's $0.99. Khan Academy also leads on update cadence (every 6 weeks vs every 11 months) and ratings volume (110K vs 52). Formula MAX's advantage is rating (4.8 vs 4.6) and iOS requirement (13.0 vs 15.0). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Khan Academy is free to download; Formula MAX costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Formula MAX 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 52, so its average is the more settled of the two. Written reviews point the same way: 80% of Formula MAX's written reviews are positive against 74% of Khan Academy's.

Formula MAX ships an update every 11 months, Khan Academy every 6 weeks. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
