## Sigma Notepad Calculator Description
£610 left this month, before the rent went out, and you never typed a sum. Sigma is a notepad that does the maths 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 sheet to the group chat as one image, every line and the total included.

Know what the trip costs before you book. Flights in pounds, 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.

And all the everyday maths around it. How many days until an invoice is due. Whether a 2.2 m sofa fits the wall. What you really saved in the sale. VAT on a £240 quote: write "vat: 20% of price" under "price: £240" and the total reads £288. 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 sheets and the full calculator. No ads, no time limit. Sigma Pro keeps every month: unlimited sheets, iCloud sync, export to PDF, Markdown and plain text, and five more themes. Billed yearly, monthly or once for life. New subscribers get a 7-day free trial on the yearly plan.

Your sheets stay on your iPhone, and iCloud sync uses your own private iCloud database, never our servers. Works in English and French.
