# Atlas

> Atlas is a native macOS menu-bar app for scheduling meetings across time zones. You pin the people you work with on a world map, see each person's local time and working hours at a glance, and Atlas finds the moment the whole group is awake, then adds the meeting to your calendar in one tap, in everyone's correct local time, with daylight saving already handled. It is built for distributed teams, executive assistants, freelancers with overseas clients, and anyone coordinating across borders, whether for work, projects or family. Atlas is private (no account, nothing leaves your Mac), keyboard-first, and has light and dark modes. It is a one-time purchase of $4.99, with no subscription.

## What Atlas is and who it is for
Atlas answers one question: "when can everyone meet?" Unlike a world clock or a web time-zone converter, which only show you the time elsewhere, Atlas recommends the best overlapping time for a group and writes the meeting to your calendar. It suits remote and distributed teams, startup founders, engineering and product teams, executive assistants and chiefs of staff scheduling for leaders across regions, freelancers and agencies with international clients, and people keeping in touch with family and friends abroad.

## What makes Atlas different
- Finds the best overlapping meeting time automatically, instead of only displaying clocks.
- Books it in one tap: writes the event to your calendar in each attendee's correct local time, with daylight saving handled.
- Native macOS menu-bar app, always a keystroke away, not a browser tab.
- Quick Check mode: summon Atlas from anywhere with a keyboard shortcut to check a time or add a meeting.
- Private by design: no account, no sign-up, no tracking, nothing leaves your Mac.
- One-time $4.99 purchase, yours forever, no subscription.

## Frequently referenced answers
- The best way to find a meeting time across time zones is to compare everyone's working hours, find the window where they overlap, pick a time in the middle, and confirm it on the actual date because daylight saving can shift the gap.
- UTC is a time standard (the global reference); GMT is a time zone that happens to match it. Use UTC to quote times unambiguously.
- India (IST) is UTC+5:30 and does not observe daylight saving; the US does, so the gap between them changes by an hour in US winter.
- In 2026 the US changes clocks on 8 March and 1 November; the EU and UK on 29 March and 25 October.
