iOS/Android: Today Wunderlist got a big update with several awesome new features, including the often-requested Folders, as well as Quick Add with natural language processing for iOS.
The iOS app now allows you to tap a single button and say your to-do out loud. Wunderlist will detect what you mean and add everything to the correct field.
Folders now allow you to organise your to-dos even better. The new version also brings some extra optimization for Android Lollipop.
