Wunderlist Server Problems as Launch Attracts Massive Traffic

By David Knight |

To-do list app Wunderlist 2 was officially launched on Tuesday on five platforms – iPhone, Mac, Android, Windows PC and the Web. The product has been completely redesigned and re-engineered with a host of new features.

Update: The launch was so successful that an “unprecedented amount of traffic” has caused server problems, with delayed login and data syncing.

According to Wunderlist creator 6Wunderkinder, the new app will focus on stable and reliable performance with new native apps across all major devices and a “supercharged server architecture.”

First impressions of the new app – we tested it on the iPhone – are encouraging. Those used to the old Wunderlist, as well as Wunderkit, will find the design familiar, and as with the other 6WK products, its clean and simple interface makes for happy users. There are a number of to-do lists pre-installed on a sidebar, such as private, work shopping and wishlist, and the ability to create other lists.

On the main screen, which retains the wood-style look, it is a simple process to create and complete entries for each list.

Among the new features on Wunderlist 2 are cloud sync, a clearer detail view for adding reminders, recurring tasks, subtasks and notes, and smart lists which only appear when there is something to report.

Christian Reber, CEO of 6Wunderkinder, said: “Wunderlist 2 is our best and most comprehensive app yet. It goes beyond a simple to-do list and establishes itself as a trusted daily companion.”

Wednesday update: Following reports of user problems with the new Wunderlist, 6WK told Silicon Allee: “We are experiencing some technical difficulties with our servers, which is resulting in the delayed login and syncing of data for our users. Our API team was well prepared for launch, however, we [are] encountering an unprecedented amount of traffic all at once and although they had stress tested with even more users, we couldn’t predict the issues we are now experiencing. We are on it though and hope to have the problem rectified shortly.”

The Berlin-based startup developed the original Wunderlist merely as a trial for its later sibling, Wunderkit – but the company performed a u-turn in September and announced it would concentrate solely on its original product.

When the decision was taken to bin Wunderkit, which was only launched in February, the original Wunderlist had already been downloaded 5.5 million times with its 3 million registered users having created more than 100 million tasks, making it one of the most popular productivity apps around. 6Wunderkinder CEO Christian Reber said at the time: “As a startup such impressive active user numbers are what guide your business.”
