RepeatableTodos is a calm app for recurring routines, reusable checklists, and real-life repeatable flows. Build routines once, keep them in Library, use what matters in Today, and preserve completed context in History. Add items like sending a message: type a line, press Return. Write "Milk;2;l" for a quantity and a unit. Shortcuts and Siri: add items and routines, and tick things off, from the Shortcuts app or by voice (English phrases for now). Use it for: - daily routines - recurring shopping - documents - recipes - household systems - repeatable work flows RepeatableTodos is local-first. It does not require an account, does not track you, and does not send your routines to a server. AIFriendly by design means your routines stay structured, readable, and portable. You can keep them local, review them yourself, or use exported routines with AI tools you choose. Designed for repeatable life, not productivity theatre.
