About

Winter Calendar

Winter Calendar turns your schedule into a briefing, not a grid. Instead of colored blocks, your week reads like a short editorial written for you: Today, Tomorrow, and This Week, in plain sentences with relative times like "tonight at 7" or "Thursday afternoon." WRITTEN FOR YOU On-device Apple Intelligence rephrases event titles and adds short notes, so you can see at a glance what matters and what to bring. PRIVATE BY DESIGN Everything runs on your iPhone. Your events come from the calendars already on your device, and the AI never sends your schedule to a server. ADD EVENTS BY TYPING Type something like "dinner with Sam Friday at 7" and Winter Calendar creates the event for you. Long-press any event to edit it, delete it, or ask about it. LIVE AT A GLANCE Events show as upcoming, happening now, or done. Overlapping events are flagged, and tomorrow's briefing is ready the evening before. WIDGETS Put your day on your Home Screen: what's on now and next, today's date, a mini calendar, or the full editorial. Winter Calendar works with the calendars you already use through iOS, including iCloud, Google, and Exchange.
