Ichi is the calmest way to do one thing at a time. Most to-do apps hand you a wall of tasks and a quiet feeling of dread. Ichi does the opposite: it collapses the whole list down to a single, beautiful screen — the one thing you're on right now. Finish it, and the next one rises gently into place. Reach the end, and the screen quietly exhales: all clear. No due dates. No "overdue." No streaks to protect, no caps to hit, no ads. Just the next thing, and the calm of knowing nothing is slipping through. ONE TASK, FRONT AND CENTER • Your single most important task, in beautiful big type • Complete it and the next one rises into place — a calm move, never confetti • An ordered "Up next" queue you reorder with a drag; the top becomes now CAPTURE WITHOUT FRICTION • Add a task in a tap — from the app, a Home Screen widget, the Share Sheet, or a word to Siri • Everything new waits quietly in the queue until you're ready for it • Nothing is ever silently deleted A WIDGET THAT'S NEVER STALE • Glance at your current task from the Home Screen, Lock Screen, or StandBy • It reads the same source as the app, so it always shows the true next thing MADE TO FEEL GOOD • Spring-physics motion, considered haptics, and Liquid Glass materials • Four hand-tuned themes — Warm Paper and Cool Mist free; Nocturne and Aurora with Pro • Light and dark, full Dynamic Type, VoiceOver, and Reduce Motion support • Private by design — your tasks sync through your own iCloud, never our servers ICHI PRO Every feature is free, forever. Pro is purely for the beauty: the Nocturne and Aurora themes, the StandBy nightstand widget, and alternate app icons. Pro is available as a one-time purchase or a yearly auto-renewable subscription, and is always restorable. Pro never sells capacity, there are no caps to lift. Do one thing. Then the next. — Ichi Pro (yearly) is an auto-renewable subscription. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically for the same price and duration unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. A one-time lifetime purchase is also available.
