Verdict
The clearest difference is review sentiment: Fraction Challenge at 70% against Heromask Mathematics's 6%. Fraction Challenge also leads on rating (4.5 vs 2.3) and ratings volume (1.5K vs 15). Heromask Mathematics's advantage is update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
