Every "=" adds the expression and answer to the note. Add headings and memos anywhere to keep it readable.

Verdict
The clearest difference is ads: *CalcMemo at none against Done Plus's shown. Done Plus's advantage is update cadence (every 3 days vs weekly) and device support (4 vs 2). On price, in-app purchases and iOS requirement there is nothing between them.
