Sigma Notepad Calculator vs CalcNote

$610 left this month, before rent went out, and you never typed a sum. Sigma is a notepad that does the math while you write: every line shows its answer, and the total stays in view above the keyboard. Know what’s left before you spend it. Write "pay = $2400", then your bills, "rent: $1200" and "food: $380", and "left = pay - total" shows $820. Rent goes up? Change one number and everything below follows. Split the bill at the table. Dinner for four, tip included, comes to $51.75 each before anyone reaches for a card. Then send the whole note to the group chat as one image, every line and the total included. Know what the trip costs before you book. Flights in dollars, the hotel in euros, the train in Swiss francs: one total, all in, in your own currency. Rates stay live and keep working offline. Never add up the same list twice. Tick what’s paid and the total shows what’s still to pay. Give each part of a list a heading and each part gets its own total. Your totals, without opening a note. Ask Siri for your Groceries total in Sigma, keep a note’s total on your Home Screen with the free widget, and set a reminder on a date in your note. And all the everyday math around it. How many days until an invoice is due. Whether a 220 cm sofa fits an 8 ft wall. What you really saved at the sale. What a week of freelance work comes to. Percentages, units, dates and currencies, written the way you’d say them, with square roots, hex and trigonometry when you need them. Every line answers as you type. No formulas, no grid, and one rule to learn: a colon counts, an equals sign doesn’t. Free: three notes and the full calculator. No ads, no time limit. Sigma Pro keeps every month: unlimited notes, iCloud sync, export to PDF, Markdown and plain text, and five more themes. Sigma Pro is a single payment or monthly. Your notes stay on your iPhone, and iCloud sync uses your own private iCloud database, never our servers. Works in English and French.

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. ■ Who it's for · Anyone who often adds up groceries or household spending · Self-employed people and freelancers calculating quotes, costs, and margins · Travelers working out trip expenses by exchange rate · Anyone splitting a dinner or group bill · Students calculating and recording figures for assignments or experiments CalcNote is free and ad-supported. A single in-app purchase removes ads permanently. There's no sign-up, and your calculation records are stored only on your device by default, so there's nothing to worry about with your privacy. Korean and English are supported. Stop re-typing the same calculation. CalcNote remembers the expression — not just the answer — for you.
