Verdict
The clearest difference is price: Qi Watermark at Free against Date Memos's $0.99. Qi Watermark also leads on update cadence (every 3 days vs every 2 months) and iOS requirement (11.0 vs 26.0). Date Memos's advantage is in-app purchases (none vs 2) and device support (5 vs 2). On ads there is nothing between them.
