Hi Product Hunt! I'm a student and independent developer, and Tidemark is the calendar I wanted for myself.
Every "smart" calendar I tried wanted my whole schedule on its servers. Tidemark does the smart parts on your device with Apple Intelligence: no account, no ads, no tracking.
What you can do:
Ask like you'd text a friend: "Am I free Friday at 3?", "What's due this week?"
Change plans the same way: "Move the dentist to tomorrow morning" finds the first opening and shows you the change before making it, with undo
Snap a flyer or ticket and it becomes events
Leave-by times with live travel time, and an alert when it's time to go
Works with iCloud, Google, Outlook, Exchange and Yahoo calendars plus Apple Reminders, on iPhone, iPad, Mac and Apple Watch
It's free to use. Pro (with a 1-week free trial) adds leave alerts, booking links, and unlimited Ask and Scan.
I'd love to hear what you'd ask your calendar. I read every comment!
