CalcNote: Calc Log & Folders

Ever finished a calculation and then thought, "wait — how did I get that number?"

A regular calculator throws the steps away the moment you tap "=". Even if you copy the result into a notes app, a few days later you can't remember how you reached it. CalcNote fixes exactly that.

CalcNote is a calculation-history notebook that saves not just the result, but the entire expression you typed. Receipt totals, household budgets, freelance quotes, travel costs in another currency, splitting the bill with friends — keep every calculation neatly in folders and pull it back up anytime.

Save the expression with the result

"38000 ÷ 4 = 9500" — the whole expression stays right above the result. Every time you tap "=", the calculation stacks up as a card, so the reasoning is obvious even weeks later. It's a world apart from jotting down only the answer.

Organize with folders, tell them apart by color

Create folders like Budget, Renovation Quote, Currency, or Group Split and sort your calculations into them. Give each folder a color to recognize at a glance, or just drop a calculation into the Unfiled bucket — it stays tidy either way. Labels are optional, so simply filing a calculation already keeps things organized, no naming required.

Money-safe, accurate math

Calculations are precise, with no floating-point errors — large amounts and decimals stay exact. You can set the rounding precision yourself, so quotes, settlements, and bookkeeping math are something you can trust.

Fast search, even as it piles up

Even with dozens or hundreds of saved calculations, find any of them with a single search. Search by expression, by label, or by the resulting number — you'll never lose "that one calculation" again.

Export / Import

Export your entire history to a single file and import it back. When you switch phones or back up, carry every calculation you've collected with you.

Light / Dark theme

Easy on the eyes in bright or dark surroundings. It follows your system setting automatically, or you can lock it to light or dark.
