Verdict
The clearest difference is in-app purchases: *CalcMemo at none against Annual Memo's 1. *CalcMemo also leads on ads (none vs shown) and update cadence (weekly vs every 5 weeks). Annual Memo's advantage is iOS requirement (14.0 vs 16.4). On price and device support there is nothing between them.
