Microsoft acquired 6Wunderkinder, the creator of the to-do list app Wunderlist, in June 2015 to be included in their broader portfolio. Wunderlist fits squarely with Microsoft's ambition to reinvent productivity for a mobile-first, cloud-first world. Building on momentum for Microsoft Office, OneNote and Skype for Business, this acquisition further demonstrates Microsoft’s commitment to delivering market leading mobile apps across the platforms and devices our customers use – for mail, calendaring, messaging, notes and now tasks.
