A calculator that remembers what your numbers were for. "Wait, what was this $385 for?" A normal calculator only keeps the answer. CalcMemo puts every calculation into a note, and lets you add a line of text in between. Quotes, budgets, splitting the bill, trip costs: come back later and you can still see what you calculated and why. ■Made for • Quotes: unit price × quantity, with item names • Budgets: monthly bills in one folder, with a total • Splitting the bill: head count and rounding, all on record • Loans: compare monthly payments and total interest • Due dates: a monthly reminder on the 25th to pay rent ■Calculator and notes on one screen Notes on top, calculator below. Every "=" adds the expression and answer to the note. Add headings and memos anywhere to keep it readable. Ans button recalls the last answer. ■Scientific functions and statistics The f(x) tab adds trig, logs, powers, factorial, parentheses and memory (M+ M− MR MC).

Verdict
The clearest difference is in-app purchases: *CalcMemo at none against ProCalc's 4. *CalcMemo also leads on ads (none vs shown) and update cadence (weekly vs monthly). ProCalc's advantage is iOS requirement (13.0 vs 16.4). On price and device support there is nothing between them.
