Plan4U: AI Calendar Planner

New: threaded comments with swipe to reply, answers straight from the notification, and reminders that finally arrive exactly when you asked.

Plan4U is a calm, beautiful planner that keeps your events, tasks and reminders on one colorful calendar — and lets you plan them together with other people.

Whether it's work, study or everyday life, Plan4U helps you see your day clearly and stay on top of what matters.

YOUR DAY AT A GLANCE • Clear day timeline — your schedule hour by hour with a live "now" line • Five views — Schedule, Month, Day, List and Year • Events and tasks together — check tasks off right from the list • A task board — park dateless ideas and to-dos under Ideas, In Progress and Done, and schedule them when the time is right • Color-coded with stickers — recognize every event at a glance • Repeats that fit your week — daily, weekly on the days you actually meet, monthly, or your own interval

ADD IT IN SECONDS • Smart quick-add — type "Lunch with Anna tomorrow at 1pm" and AI fills in the details • Ask Siri to add an event without opening the app • An AI assistant inside the editor — say "move it to Friday at 6 and remind me an hour before" and watch the event rewrite itself • Share a link, a note or a photo into Plan4U from any app

PLAN IT TOGETHER • Invite people and see who's coming • Shared statuses with history — everyone sees what changed and when • Threaded comments — discuss an event where it lives, and reply straight from the notification • Attach files and photos to an event

NEVER MISS IT • Reminders that arrive exactly on time, plus a second reminder for what matters • A morning briefing with the day ahead • Answer from the notification — accept an invitation, tick a task off, reply to a comment • Home Screen widget with your next events • Apple Watch app for your day on your wrist

MAKE IT YOURS • Light, dark or system theme • 8 accent colors • Card, Compact or Timeline list styles

WORKS WITH YOUR CALENDAR • Two-way sync with Apple Calendar • Sign in with Apple or Google
