Verdict
The clearest difference is in-app purchases: Memorize Binary at none against Cross Sum's 1. Memorize Binary also leads on ads (none vs shown) and iOS requirement (14.0 vs 17.0). Cross Sum's advantage is update cadence (every 4 months vs every 32 months). On price and device support there is nothing between them.
