MonoTape - Calculator Memo

"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 "=".
