Verdict
The clearest difference is ads: iStroopChallenge at none against LogicSums's shown. iStroopChallenge also leads on update cadence (every 6 days vs fortnightly) and monetization model (free vs ad-supported). LogicSums's advantage is iOS requirement (13.0 vs 15.0). On price, review sentiment, in-app purchases and device support there is nothing between them.
