*CalcMemo - Calculator Notes*

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). Select calculations in a note to see their sum, mean, max, min and standard deviation.
