Crowdtesting the official German Corona Warn-App

Jun 17, 2020 | News & Infos, Crowdtesting, Usability & User Experience

After yesterday’s launch of the official Corona Warn-App, we started a crowdtest of the app that ran for 24 hours.

231 testers across all German states participated and tested the app on 101 devices from 15 different manufacturers running on different operating system versions.

Corona App Test – The Results

Overall, the Testbirds Crowd didn’t find any critical bugs and gave the app a high rating from a UX perspective. 

The app received an overall rating of 4.3 stars from our testers and an NPS score of +49. (The NPS score is one standard measure in the field of UX testing and is calculated on how likely it is that a customer would recommend a company, product, or service to a friend.)

Most of the bugs found were only minor issues, such as spelling mistakes. Nevertheless, we’ve gathered all the bugs found and will be sending the list to the app developers. Generally, we can say that the app is highly developed already – more so than most of the early app versions we normally see in our daily work. 

We also asked our testers if they’ll continue to use the app after the test as well and 85% said that it was likely or very likely that they would.
Those who said they wouldn’t had three main concerns

  • Data security
  • Battery consumption 
  • Effectiveness of the app as a measure to fight Coronavirus

Although the government and the app developers have already addressed those user concerns, especially regarding data security, it seems there’s still room to further improve. Addressing battery consumption and giving more details on why and how the app helps to break infection chains is one recommendation we derived from the test results. 

But still, most users are very positive about the app (these quotes have been translated):

“All in all, very simple and stable! Great.”

“I think the Corona Warn-App is very good because you’re warned by a message if you’re at risk of infection. I also like the design a lot and everything is explained well and in detail, so I would recommend this app to other people.”

“The app is designed very clearly and limited to the bare essentials. This allows good usability for all potential customers.”

Those voices show that the German federal government, together with developers of the app, SAP and Deutsche Telekom, heard the users’ concerns and tried to minimize them as much as possible.

You can literally see that a lot of experts worked together here. Normally, we find a lot of critical bugs in the first versions of apps and usability is usually far from the level we have here, so a lot of experience was put into making it.”

Further Information on the Corona Tracing App

Yesterday (June 16th) was the official launch of the Corona Warn-App in Germany and it’s now available for download in the app stores. The app was long-awaited and will help break chains of infection as early as possible. To ensure that the app has a real benefit, literally every download counts – so far the app has been downloaded over 1 million times

As data security remains the biggest concern among users, I recommend reading this FAQ or watching the following video (German only) as it gives a clear explanation of what data is saved and how. 

We’ve already helped on Corona-related projects like the Wir-vs-Virus hackathon, where we supported the development teams with free crowdtests, and we continue to provide pro bono testing for solutions tackling the Coronavirus

If you’re interested in the topic, read our blog post: Digital Hackathon #WirvsVirus

We really recommend downloading the app and using it to break infection chains, contributing to stopping the virus and helping us all return to a normal life again, as soon as possible.
