Mindwtr - GTD Task Manager

Mindwtr (pronounced "mind water") is a free, open-source task manager and to-do list built for Getting Things Done (GTD).

It is local-first and privacy-first by default. No account required. No cloud dependency. Your data stays on your device unless you choose to sync, export, or back it up.

Use Mindwtr as an offline task list for your whole life: capture inbox items, clarify next actions, organize projects, and review what matters without giving a company your personal task data.

KEY FEATURES:

- GTD task manager: Inbox, Next, Waiting, Someday, Projects, Areas, and Contexts map directly to the Getting Things Done workflow.
- To-do list and offline task list: Works without an internet connection, with fast local storage on your device.
- Kanban board: Visualize work with board view and drag-and-drop task flow.
- Projects and Areas: Keep complex goals organized without turning every task into a calendar event.
- Review workflow: Daily and weekly review tools help you keep commitments current.
- Optional sync and backup: You decide if and where data syncs.
- Open source: Transparent code, no account lock-in, and no subscription required.

PRIVACY BY DESIGN:

- No account required.
- No cloud dependency.
- Your data stays on your device.
- Mindwtr does not sell your task data.

Whether you are a GTD veteran, building a private to-do list, or looking for an offline task manager with kanban board support, Mindwtr helps you reach mind like water.
