Sigma Notepad Calculator vs EdgeEver

Type your math. Sigma calculates as you write. A notepad where every line is a working calculation. Type "rent 1200, food 380, transport 95" and Sigma adds them. Write "20% of 240" and the answer appears beside the line. Name a value, reference it three lines down, and every dependent answer updates when you change the source. Free forever for everyday use: three sheets, full calculator, no ads. Upgrade to Sigma Pro yearly, monthly, or once-for-life when you need unlimited sheets, export, and iCloud sync. Highlights: - Natural language arithmetic. Operators read like English. Percentages, totals, averages, and units all work the way you write them. - Named variables. Declare once, reference everywhere. Changes propagate. - Currency. Live rates with offline cache. Tap a line to see when rates were last 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.
