In one point almost all messengers fluff at Stiftung Warentest

Private communication has long meant using messengers. The selection of such apps is large. Because it is convenient, many simply go for the market leader. But is that the best choice? A test reveals it.

Secure end-to-end encryption, versatile functions, ease of use and sparing use of user data: These are the requirements that Stiftung Warentest places on a good messenger.

In a recent comparison of 16 corresponding apps, only 4 applications more or less met these requirements and received the overall rating of good (“test” issue 3/22).

Only four good smartphone messengers

The test winner was Signal (grade 2.3). The messenger scores with versatile functions as well as easy operation and convincing encryption. Viber and Wire were rated “very good for messaging” by the product testers. They share second place (both rated 2.5) with Skype, which is particularly good at video calls, but weakens when it comes to encryption.

Market leader WhatsApp shares third place with Line. However, the overall score of 2.6 in each case only corresponds to the overall rating of satisfactory. The testers rated positively that WhatsApp uses end-to-end encryption as standard.

Poor data privacy statements

However, the app collects massive amounts of user data and shares some of it with parent company Meta (formerly Facebook). The Stiftung Warentest recommendation is therefore Signal: This messenger is functionally better and offers more settings and security options.

With the exception of Wire, the experts found significant deficiencies in the privacy policy of all apps. Stiftung Warentest devalued these apps, which is the main reason why they did not receive a very good overall rating in the test field.
