Microsoft Corp. is reported to have acquired German company 6Wunderkinder GmbH, the makers of the list making application Wunderlist.

The Wall Street Journal quotes sources that put the acquisition figure as between $100 million and $200 million.

6Wunderkinder was founded in 2010 with the Wunderlist app being released in 2011, and as of today is their only product.

Wunderlist itself offers, as the name hints at, a “wonderful” (an exaggerated description, but it is a decent enough app) list making and management app and supporting website. Users are able to make multi-stage lists that can share a users to-do, work, grocery, movies, and household lists.

Users are able to set due dates and reminders and assign to-dos to other people who use Wunderlist, and lists can be shared across a group, complete with the collaboration tools such as chat and file share.

Support is multi-platform, with software available for both OS X and Windows, a plugin for Google Chrome, along with apps for iOS, Android, and Windows Phone. On Google Play the Wunderlist app has been downloaded between 5 million and 10 million times, with 180,000 reviews giving it a rating of 4.4 out of 5; the app has also been given the ranking of “editor’s choice.”

The acquisition for Microsoft is another company to add to their list as the once laboring tech giant continues its renewal with cloud and mobile services. Wunderlist’s acquisition follows in the footsteps of its acquisition of calendar app Sunrise in February, and Acompli in December.

Of note, 6Wunderkinder had recently announced a deal with Sunrise in May that allowed users to see their to-do lists in the Sunrise app, and also create to-do items from their Sunrise calendar app.

It’s not clear whether Wunderlist will remain in its current form or being integrated either by name or form into something more Microsoft vanilla, such as with Acompli which is now known as Outlook for Mobile.

Prior to acquisition 6Wunderkinder had raised $23.9 million over 5 rounds. Investors included Earlybird Venture Capital, Sequoia Capital, Atomico, High-Tech Gruenderfonds and T-Venture.
