OpenTime
Your free time, inside a link.
OpenTime reads your calendars on your iPhone and turns the gaps into a link. They choose the times that suit them and send them back. No server ever sees your week.
$0.99, once. No subscription.
Try it with a made-up week
Tap a time to take it out of the link. Watch the link change: the times live inside it.
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.
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.
Or ask your assistant.
If your assistant can see your calendar, it can find the gaps and send the link for you. Add OpenTime once, then ask in plain words.
Add it onceGive your assistant this address. Each app's way is under its video.
https://lulls.app/mcpMake a linkFrom free time your assistant already knows, ready to paste into a message or an email.
Read the replyPaste what they send back and it lists their picks in your time zone.
Confirm itPick one and it makes the link that puts the meeting on their calendar.
Any assistant that speaks MCP can use it, with no sign-in and no key. It stores nothing and never sees your calendar.
In Claude, open Settings, then Connectors, and add it as a custom connector.
On your Mac or PC, one click installs it in Cursor. Then ask its agent for a link.
Ask Grok Bot to use the address. It offers to add it as a custom connector, then makes the link.

Apple WatchYour next five weekdays on your wrist.
Any appThe share sheet drops clean, readable times into Mail, Slack or Notes.
Your calendar is read on your phone and stays there.
No account, no analytics, no tracking, and the app makes no network connections. A link carries only the free times you chose, plus your first name and a number or email if you add them. Their reply carries only the times they picked, plus their number or email if they add one. Read the privacy policy.
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 up to five times and send them back; you confirm one and add it to your 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.
