Myrmex

Myrmex keeps your tasks: an Inbox for what comes up, projects with
sections, sub-tasks and labels, Today with what is overdue, and Upcoming as
an agenda that opens into the month. Tasks repeat (every day, every other
Tuesday, the first Monday of each month), have reminders, deadlines and
priorities, and are typed the quick way: "Call Anna tomorrow 9am #Home p1".

Each project shows as a list, a board or a calendar, grouped, sorted and
filtered as you set it, the same on every device. Tasks are dragged between
sections, days and hours.

Everything is sealed on your device with your account's keys before it
reaches the instance, which can't read it. You sign in with SimpleLogin, by
Proton, or with an email address, a password and an authenticator app. It
connects to myrmex.li, the project's instance, or to any other:
everything an instance needs is in the repository, to run your own. The app
is AGPL-3.0 and the server SSPL-1.0, so all of its code is public.
