Tidemark is the calendar you can just ask. Every calendar in one place — with the weather, travel time and reminders built in — on iPhone, iPad, Mac and Apple Watch. Private by design: no account, and the AI runs on your device.
KNOW WHEN TO LEAVE
• Live travel time from where you are, your last event or home — by car, transit, bike or on foot
• “Leave by” on every event with a place, updated as you move
• Leave alerts with the weather where you're going: bring an umbrella, dress warm, leave a few minutes early (Pro)
ASK TIDEMARK
• Ask about your time in plain English: “When am I free for an hour this week?”, “What's after standup?”, “Should I bring a jacket tomorrow?”
• Answers come straight from your calendar — exact, never made up
• Works on every device; with Apple Intelligence it also understands typos and looser questions
SCAN TO EVENT
• Snap a flyer, ticket or screenshot, or drop in a PDF, and Tidemark finds every event, with its time and place
• Flights come out right: number, airports and times in each time zone
• You check every event before it's added
EVERY CALENDAR, ONE PLACE
• iCloud, Google, Outlook, Exchange, Yahoo and CalDAV — no extra sign-in
• Subscribe to any ICS feed: holidays, sports, school terms, travel
• Day, 3-day, week, month, year and list views; drag to reschedule, even across days
YOUR DAY, BRIEFLY
• A short daily brief: the weather, what's next, your longest free stretch and when to leave
• Clash radar spots double-bookings and trips you can't make in time
• Week Tides: booked vs. open time, your busiest day and best focus window
PLAN IN PLAIN ENGLISH
• “Lunch with Sam tomorrow 1pm at Tartine for 45m”
• “Standup every weekday 9:30am #work”
• “Remind me to call Mom Friday 6pm”
REMINDERS THAT DON'T SLIP
• Works with Apple Reminders, right on your calendar
• Unfinished reminders roll over to the next day
• Time-block a task into your next free slot (Pro)
LET PEOPLE BOOK YOU (PRO)
• Share a booking link with your open times, with breathing room around your events
• Guests pick a time and a place; nothing is added until you accept, and they see your answer
• End-to-end encrypted — no accounts, nothing readable on any server
EVERYWHERE, IN SYNC
• iPhone, iPad, Mac and Apple Watch update in real time
• Beautiful widgets for light and dark — plus an always-dark set — on the Home Screen, Lock Screen and desktop
• Watch complications, Siri and Shortcuts
