Verdict
The clearest difference is ads: Unbreakable Blocks at none against iMemory's shown. Unbreakable Blocks also leads on iOS requirement (12.0 vs 16.0). iMemory's advantage is update cadence (monthly vs every 12 months). On price, in-app purchases and device support there is nothing between them.
