Verdict
The clearest difference is in-app purchases: Mathstep at none against Immersea's 2. Mathstep also leads on update cadence (every 3 days vs every 10 days) and iOS requirement (12.0 vs 15.1). Immersea's advantage is ads (none vs shown). On price and device support there is nothing between them.
