It was more than four years ago that Microsoft confirmed it would be acquiring Wunderlist, a popular app for to-do lists at the time. Then, two years later, Microsoft To Do (then stylized as To-Do) was released as a successor to Wunderlist, indicating that the older app would be retired. In the two years since then, the company never gave a specific date for the death of Wunderlist, but that changes today.
In a blog post on the Wunderlist website, the Microsoft To Do team announced that the service will no longer be supported after May 6, 2020. This means that to-do items will no longer sync between devices after that point, but starting today, Microsoft is already blocking the creation of new accounts for Wunderlist.
Over the past two years, Microsoft has made a slew of improvements to Microsoft To Do, bringing it closer to the feature set of Wunderlist. Features like sub-tasks for each task, list groups, shared lists, and file attachments have been added over the months and years. Microsoft To Do also offers even more background options than Wunderlist, as a result of a UI refresh back in September.
If you've been using Wunderlist, moving to To Do should be relatively easy. The To Do app lets users import their Wunderlist items, making the transition easier. Importing items into To Do will work for a while after the announced end of support, but it probably won't be for long, and you might not get a warning when it's set to happen, so you'll want to move as soon as possible. You can download Microsoft To Do, or access the web version of the app, on its official website.
