Octuple Calc vs *CalcMemo

Display eight calculators and perform calculations with each one.

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).
