Wunderlist

Cause of death

Killed by a successor

Made by

6Wunderkinder

Microsoft replaced Wunderlist with its own To Do app and switched the original off once the feature migration was finished.

Berlin startup 6Wunderkinder launched Wunderlist in November 2010 and sold it to Microsoft in June 2015. Microsoft announced its own replacement two years later, then took another three years to actually pull the plug, migrating features into To Do rather than forcing anyone across. The original finally stopped syncing on 6 May 2020, nine and a half years after launch, having outlived the company that made it by half a decade.

Replaced by Microsoft To Do.
