Planify
Different way of workingFreeA proper Linux task app with projects, reminders and repeats. It does not talk to Microsoft To Do, so this means moving services.
Your files: No Microsoft To Do import. Lists have to be recreated by hand.
Does Microsoft To Do run on Linux?
Verdict: Partly
Partly. Microsoft does not make a To Do app for Linux, but the web version at to-do.office.com holds your whole list and syncs with your phone and Outlook as usual.
There is no To Do app to install on Linux. What Microsoft offers instead is the full web version, which is the same service in a browser tab.
The web version is the answer and it is not a cut-down one. Sign in with the same Microsoft account and you get My Day, your lists, shared lists, steps, due dates, reminders and the tasks that Outlook flags for you. Your phone carries on working exactly as it did. Most browsers will let you install the page as its own window so it behaves like an app in your dock.
Reminders are weaker. Windows pops them up through the system. In a browser they arrive as browser notifications, and only while the tab is open, so a to-do at 3pm may not chase you the way it used to.
Nothing is stored on the Windows PC that you need to save. If you would rather have a real Linux app, Planify is free and good, but it syncs with Todoist, Nextcloud and CalDAV rather than with Microsoft To Do, so you would be changing services as well as apps.
