Verdict
The clearest difference is ads: Humanform at none against Sand Nihongo's shown. Humanform also leads on update cadence (every 2 days vs every 2 weeks) and device support (5 vs 3). Sand Nihongo's advantage is iOS requirement (15.5 vs 18.0). On price and in-app purchases there is nothing between them.
