Semo
Notepad Calculator
Semo is a notepad calculator for iPhone, iPad, and Mac that lets you write calculations alongside your notes and see your totals update as you type. Keep budgets, expenses, and everyday math in reusable workbooks, with individual line results beside your notes when there is enough screen space.
Your workbooks are stored on your device and can sync across your devices through your private iCloud account. Semo does not require a separate account and has no analytics, advertising, tracking, or telemetry.
Semo Pro unlocks unlimited workbooks and folders with a one-time in-app purchase. There is no subscription.
