Verdict
The clearest difference is in-app purchases: Nonuple Calc at none against Diary Notes's 1. Nonuple Calc also leads on iOS requirement (15.8.3 vs 26.0). Diary Notes's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 weeks). On price and device support there is nothing between them.
