Verdict
The clearest difference is in-app purchases: Gratuity Lab at none against TapMemo's 1. Gratuity Lab also leads on update cadence (every 5 days vs every 4 months) and iOS requirement (17.0 vs 26.2). TapMemo's advantage is ads (none vs shown). On price and device support there is nothing between them.
