# An offline task manager that keeps working in airplane mode > Yes. Done Bear keeps a full copy of your tasks on your device, so you can add, edit, complete and search them with no connection. Changes sync when you reconnect. ## What works with no connection | App | Opens with no connection | Add, edit, complete and search | | --- | --- | --- | | iPhone app | Yes, once you have signed in | Yes | | Web app | Yes, in a browser where you have used it online before | Yes | | Desktop app for Mac, Windows and Linux | No. It loads donebear.com at start, so use a browser instead | Yes, if it was already open | Needs a connection: First sign-in, uploading or opening attachments, inviting people, the in-app assistant, and the MCP server, CLI and API. [Start free](/sign-up) ## How it works Done Bear is local-first: your tasks live in a database on your device, and every change is written there first, then queued. When you reconnect, the queue sends your changes in order and the server puts every device’s changes in one order. If the server refuses a change, such as one past the free plan’s task limit, the app undoes it and tells you why.

Closing the app, logging out or clearing local data before a sync deletes unsynced changes.

Turn on airplane mode, reopen it, add a task and complete another. Reconnect and open a second device: both changes are there. ## Frequently asked questions ### Does Done Bear work offline? Yes. On iPhone, and in a browser you have used online before, it opens with no connection; the desktop app needs one to start. ### Do I need to be online the first time? Yes, once: signing in and the first download of your tasks to a new device need a connection. ### What happens if I edit the same task on two devices? Changes to different fields both stay. For the same field, the change the server receives last wins on every device. ### How much does Done Bear cost? Free for up to 250 tasks with no card. Paid plans start at $7/month per member billed yearly. ## Related pages - [What a local-first task manager is, and how to test one](/blog/local-first-task-manager) - [Download Done Bear for iPhone, Mac, Windows and Linux](/download) - [Things 3 alternative](/things-3-alternative) --- Free for 250 tasks with no card.
