Verdict

The call

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.
