# 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 2.0.5.

## Features

## 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, grouped by day in any time zone.
- 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.
