OpenTime

Your free time, inside a link.

Your week, as free time.

Open the app and the gaps are already worked out: every free half hour between your meetings, inside your working hours, from the calendars that count.

The Calendars sheet in OpenTime with Calendar and Birthdays on and US Holidays switched off

Only the calendars that countLeave out holidays, a partner's shared calendar or the kids' sports. Declined invites and events marked Free never count against you.

Ask in plain wordsType "tomorrow afternoon for 30 min" and Apple Intelligence finds it on your device, so the question never leaves it.

Act on a timePress and hold a time to create an event there, open it in Calendar or copy it.

Send a link. They pick.

Instead of pasting a list of times into a message, send one link. On iPhone it opens straight away as an App Clip, with nothing to install. Anywhere else it opens in the browser.

Questions people ask.

Does it work with Google Calendar or Outlook?
Yes, if those accounts are set up in the iPhone's Calendar app. OpenTime reads them through Apple's EventKit and never talks to Google or Microsoft itself.
Do I need Apple Intelligence?
Only for typing questions in plain words. Everything else works on any supported iPhone.
Does it book meetings?
No. A pick-a-time link lets them choose a time and reply or add it to their calendar. OpenTime does not hold the time for you, and there is no account or booking page to manage.
What does it cost?
$0.99, once. No subscription and no in-app purchases.
What do I need?
iOS 26.2 or later on iPhone, iPadOS 26.2 or later on iPad, and watchOS 10 or later on Apple Watch.
