MonoTape - Calculator Memo

Calculator meets notepad. Save labeled calculations, reference past results, and auto-recalculate when you change a value.

"What was that number for?" Never again.

You finish a calculation, but minutes later you can't remember what the numbers meant. Change one value, and you have to redo everything from scratch. MonoTape solves both problems.

MonoTape is a calculation notebook that combines the simplicity of a calculator with the record-keeping power of a notepad. Just type on the keypad and press "=". Results are saved to a history tape, and you can label each line so you always know what it means.

-- What MonoTape Does --

[1] Labeled Calculations "Rent", "Utilities", "Food" -- attach a label to any result. When you look back later, you instantly know what each number was for.

[2] Reference Past Results Pull in previous results by their label and use them in new calculations. "Rent + Utilities + Food = Total" -- it works like a spreadsheet, but feels like a calculator.

[3] Auto-Recalculate Edit one value and every calculation that depends on it updates automatically. No need to start over.

[4] Calculator-First Input Input is keypad-only. It feels exactly like a regular calculator. No learning curve at all.
