Read full descriptionHide full description
Fountain Notes opens to a blank note so you can get an idea out before it slips away. No formatting maze. No folders to manage. No decision fatigue before the thought is even written. Write the note, file it away, and move on. Fountain Notes keeps old notes organized automatically and hidden from view until you need them. Search and the drawer are there when you want to find something, but they do not crowd the writing surface. Built for quick ideas, tiny reminders, quotes, fragments, and the little thoughts that usually vanish while you are deciding where they belong. Fountain Notes is intentionally small: - Blank note first - Fast local saving - One thought at a time - Clean search - Calm history drawer A quiet place to catch the thing and keep going.

$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. 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.
