# OpenTime

> OpenTime is a private iOS, iPadOS, and watchOS app that reads your device calendars on-device through Apple's EventKit and shows your free and busy time slots at a glance. No accounts.

OpenTime is a $0.99 download on the Apple App Store and runs on iPhone, iPad, and Apple Watch. It is built and maintained by James Tannahill. The current version is 2.5.

## Features

- Instant availability: visual free and busy slots for any range; weekends optional; refreshes automatically after you create or edit an event.
- Natural-language queries: Apple Intelligence on-device for phrases like "tomorrow afternoon for 30 min."

- Pick-a-time links: share a lulls.app/pick link; the recipient chooses up to five times in their own time zone, in an App Clip (no install) or any browser, and sends them back as a lulls.app/reply link that opens in OpenTime, where the sender confirms one. Times travel in the URL fragment; no server receives them.

- Apple Watch: standalone watchOS companion with a five-weekday glance.
- Share extension: drop availability as clean text into Mail, Slack, Notes, or any app.

## MCP server

- Endpoint: https://lulls.app/mcp (Streamable HTTP, JSON-RPC over POST, no authentication, stateless).
- Tools: `create_pick_link` turns free time (ISO 8601 stretches with an offset) into a lulls.app/pick link someone opens to choose a meeting time; `read_pick_link` lists the times in such a link, a reply or a confirmation, grouped by day in any time zone; `find_common_times` lists the times in a link (or someone's free stretches) that fit the user's own free time; `create_reply_link` answers a link with up to five of its times; `create_confirmation_link` turns the agreed time into a lulls.app/confirmed link that adds the meeting to the other person's calendar (Apple, Google or Outlook) in one tap.
- Privacy: the times travel in the link's fragment. The server stores nothing and never sees a calendar.

## Audience

OpenTime is built for freelancers, consultants, founders, lawyers, therapists, sales professionals, and anyone whose calendar is a working document rather than a marketing surface.
