Microsoft has announced in a blog post that it is shutting down Wunderlist on May 6, 2020.

Microsoft acquired 6Wunderkinder, maker of the popular app, four years ago and began creating its own in-house replacement two years later. The company’s plan was always to replace Wunderlist with To Do, rather than maintain both applications. Development has focused on migrating those features Wunderlist users depend on to the new application.

Microsoft’s blog post makes it clear they believe the time has come when most users will be able to migrate over with ease.

“As a team of over 26 nationalities, we at Wunderlist/Microsoft To Do know what it’s like to move your life from one place to another. Be it a city or an app, moving can be stressful and scary – but, more importantly, exciting and refreshing. The key to a successful move is having the support to make your transition as seamless as possible, so you can focus on enjoying all the new experiences and creating new memories (or to-dos).”

As part of the transition, users will be able to continue using Wunderlist for the time being, although it’s clear they should begin migrating to To Do as soon as possible.

“Why are we doing this now? We’ve stopped releasing new features and big updates to Wunderlist, so as the app ages it’s become more difficult to maintain. As technology continues to advance, we can’t guarantee that Wunderlist will continue to work as it should, or as we’d like it to. With all our latest updates, we’re confident in To Do being the best alternative for Wunderlist now and so we believe it’s the right time to make the next move. Now, we want to dedicate all our time to growing that cross-suite experience that transforms how you achieve your goals and dreams.”

After May 6, 2020, Wunderlist to-dos will no longer sync, although data will still be able to be exported to other platforms or imported into To Do for some time past the shutdown date. In the meantime, Wunderlist is not accepting any new signups in preparation for the transition.
