About Lumi: Chat To-Do & Reminders

Say it. It's on your list. Lumi is a to-do list you talk to. Type or dictate the sentence in your head — "Remind me to call the dentist tomorrow at 4pm" — and it becomes a real to-do with the date, the repeat and the reminder already set. No forms. No date pickers. No account. WHAT MAKES LUMI DIFFERENT ▸ It understands you on the device, not in the cloud. There is no sign-up, no server, and nothing sent anywhere. Lumi reads what you write right on your iPhone — so it works on a plane, in a basement, and on the private things you would rather not hand to a data centre. ▸ It asks instead of guessing. Most assistants guess, and a wrong to-do costs more than a question. When something is missing, Lumi asks for that one thing — and every question comes with a way out. ▸ One sentence can become a whole plan. "Set up a project called Move house: find a flat, sign the lease, pack, hire movers, move. First one next week, one a week." Lumi lays out the steps, dates them, and marks which dates are yours and which it suggested. Nothing is written until you tap Create. ▸ Change many things at once. Undo them at once. "Move the lease signing, the packing and the movers all to next week" shows you exactly what will change before anything does — then takes it all back with one tap. ▸ A nudge, not a nag. One kind message a day: the shape of your morning, a gentle wind-down at night, your week in one breath. No streaks to defend, no guilt. AND THE REST OF IT • Natural-language dates and repeats — "next Friday", "every Wednesday", "the 20th of every month" • Reminders you set in words: at the time, 15 minutes before, that morning • Today, Upcoming, Anytime and Projects, plus Deadlines, Someday, Logbook and Trash • Drag to reorder and reschedule anything • A Home Screen widget that shows today — and lets you tick things off without opening the app • Undo everywhere, and a log of every change Lumi made for you YOUR DATA Everything lives on your iPhone. There is no account, no analytics, and no upload. If you want your to-dos on your other devices, iCloud Sync puts them in your own Apple ID — not ours. Lumi is for the person who has tried every to-do app and abandoned every one of them, because keeping them up to date was more work than the work.

What’s new

Version 2.0 · Updated October 7, 2026

Lumi 2.0 — Say It. It's on Your List. The to-do app you talk to — now with a whole plan from one sentence. Most to-do apps make you fill out a form: title, date, time, repeat, reminder. Lumi makes you say one thing. "Remind me to call the dentist tomorrow at 4pm." Done. Date, repeat, reminder — all set. No forms. No date pickers. No account. What's new in 2.0 One sentence, a whole plan. Say your steps — "Set up a move: find a flat, sign the lease, pack, hire movers." Lumi lays them out, dates them, and marks which dates are yours and which it suggested. Nothing is saved until you tap Create. Move five things at once. Undo in one tap. See exactly what will change before anything happens — then take it all back with a single tap. Every change Lumi makes is on the record. Nothing you say leaves your iPhone. No account. No cloud AI. No server of ours. Lumi understands you right here, on the device in your hand — so it works on a plane, and it's safe for the private stuff. It asks. It doesn't guess. A wrong to-do costs more than a question. When something's missing, Lumi asks for that one thing — and every question comes with a way out. A nudge, not a nag. One kind message a day. No streaks to defend. No guilt. No red overdue counters. Your day, one glance away. A Home Screen widget that shows today — and lets you tick things off without opening the app. Still true in 2.0 • Natural-language dates and repeats — "next Friday," "every Wednesday," "the 20th of every month" • Today, Upcoming, Anytime, Projects, Deadlines, Someday, Logbook, Trash • Drag to reorder or reschedule anything — and every reminder moves with its task • Undo everywhere Lumi is for the person who has tried every to-do app and abandoned every one of them — because keeping them up to date was more work than the work. Try Lumi 2.0. Say it. It's on your list.
