Verdict
The clearest difference is in-app purchases: Mental Math Interview Trainer at none against CaseBuddy.ai's 1. Mental Math Interview Trainer also leads on update cadence (every 2 days vs weekly). CaseBuddy.ai's advantage is ads (none vs shown) and iOS requirement (18.2 vs 26.4). On price and device support there is nothing between them.
