Your head keeps reminding you of things at the worst times. Mindwtr gives them a safe home. Mindwtr (pronounced "mind water") is a free, open-source to-do app built on the Getting Things Done (GTD) method. Write down every task and idea the moment it appears, sort it in seconds, and see only what you can do right now. No account, no subscription, and your data stays on your device. HOW IT WORKS 1. Dump it. A task, an idea, a worry: type it or speak it, and it lands in your Inbox. 2. Sort it. A short guided pass: do it now, schedule it, hand it off, or shelve it for someday. 3. Do it. The Focus view shows only what you can act on right now, nothing else. 4. Reset weekly. A guided review catches loose ends, so the list stays trustworthy and your head stays clear. New to GTD? The idea is simple: your head is for having ideas, not for holding them. Mindwtr walks you through every step. WHY MINDWTR - Works completely offline. No account required. - Your tasks stay on your device. Sync is optional and you choose where: Dropbox, a folder you control, WebDAV, your own server, or iCloud on Apple devices. - The full GTD method built in: Inbox, Next, Waiting For, Someday/Maybe, Projects, Areas, Contexts, and reviews. - Capture from anywhere: quick add, widgets, sharing from other apps, or voice. - Plan your way: list, calendar, and kanban board views. - Reminders, repeating tasks, checklists, Markdown notes, and attachments. - Import from Todoist, TickTick, OmniFocus, and more. - Free and open source. No ads or lock-in. SIMPLE BY DEFAULT, POWERFUL WHEN YOU NEED IT Fewer fields, fewer knobs, no clutter. Advanced tools, like the kanban board, automation, and an optional AI assistant that uses your own AI account, stay out of sight until you want them. Mindwtr means "mind like water": the calm you get when nothing is rattling around in your head.
