About Mindwtr
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.
Privacy and F-Droid
