Sigma Notepad Calculator
Read full descriptionHide full description
Write your bills, a trip or a dinner to split as a note. Every line shows its result as you type. Your monthly bills, the way you think about them: "rent: 1200", "food: 380", "transport: 95", then "rent + food + transport" shows 1675. Change the rent and every line that uses it updates. No equals sign, no formulas, no grid. Splitting dinner? Write "dinner: 240", "tip: 15% of dinner", then "(dinner + tip) / 4" for each share. Planning a trip? "hotel: $85 times 3", "flights: $420", then "hotel + flights". Free with three sheets and the full calculator. No ads, no time limit. Sigma Pro unlocks unlimited sheets, export, iCloud sync, and five more themes, billed yearly, monthly, or once for life. New subscribers get a 7-day free trial on the yearly plan. Highlights: - Money notes. Bills, trips, shared costs and quick estimates, written as plain lines with a result beside each one. - Named values. Name a number once and use it on any line below. Change it and every line that uses it updates. - Natural language arithmetic. Operators read like English: times, plus, of. Percentages, averages, units, and dates work the way you write them. - Currency. Live rates with offline cache. When rates are out of date, a dot appears on the line; tap it to see when they were fetched. - Themes. Six themes including a high-contrast option. The default follows your system light and dark; five more unlock with Sigma Pro. - Sheets. Up to three sheets on the free tier. Sigma Pro unlocks unlimited sheets, export to PDF, Markdown, and plain text, plus iCloud sync across your devices. - Private by default. Sheets stay on your device. iCloud sync uses your private database, never our servers. - Designed for iOS first. Reads French and English natively. No web app, no ads, no surprise pop-ups. - For the technical side: hex, square roots, and trigonometry are there too.
