Sigma Notepad Calculator vs Orbit

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 When rates are out of date, a dot appears on the line; tap it to see when they were fetched.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.

Orbit is a second brain for the things you don't want to forget — moments, ideas, voice notes, photos, the link you saved at 2am. Everything lives in one calm timeline that AI quietly organizes for you. No tagging. No folder hierarchy. No notification fatigue. Just capture, and let Orbit find the meaning later. — WHAT YOU GET — • Capture anything in seconds — text, voice memos, photos, links, screenshots, even a place. Apple Intelligence handles the rest: titles, tags, summaries, categorization. • Daily Recap — a one-paragraph reflection of your day, generated each evening from the moments worth revisiting. • Ask Orbit — chat with your own memories. Ask "what did Pamela say last weekend?" or "what was the restaurant in Roatan?" Orbit answers from your captures, never from the cloud. • On This Day, Year in Review, Time Capsules — Orbit surfaces your past at the right moment. • Tasks that find themselves — write "I should call mom tomorrow" anywhere in a memory and Orbit suggests it as a task. Promote what you mean. Ignore what you don't. • Reading list & habit tracking — captures like "I want to read…" or "ran 5k" land in their own surfaces, quietly tracked over time. • Beautiful share cards — turn a memory, a Daily Recap, or a Year in Review into an editorial-quality image, ready for Stories, iMessage, or just keeping. • Privacy by design — On-device AI via Apple Intelligence. Voice transcribed locally. Sleep + steps stay on your phone. iCloud sync runs end-to-end. Nothing is sold. Nothing is shared. — DESIGNED FOR APPLE — Lock Screen camera capture · Apple Watch voice notes · Siri Shortcuts · Spotlight search · Home Screen widgets · Safari extension · Share extension · iOS Reminders & Calendar sync · HealthKit sleep + steps in your Daily Recap — PRO — A monthly or annual subscription unlocks unlimited captures and the full AI surfaces. Cancel anytime from Settings → Subscription. — WHY WE BUILT IT — Journaling apps ask too much. Note apps forget everything. The things we want to remember keep slipping away. Orbit is what we wished existed — a calm, native, private place where life can quietly accumulate, and an AI that helps you find what matters without taking over the experience.
