Verdict
The clearest difference is in-app purchases: Christopher at none against MathTre's 1. Christopher also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.2). MathTre's advantage is update cadence (every 6 weeks vs every 4 months). On price and device support there is nothing between them.
