User comments

Unlike most apps in Germany, this one is really good, eases the need to move and turns operations that required papers and moving to branches things of the past. Now most of those operations can easily be done online through this easy to follow app, which also has an English version! Really pleased with this service, thank you.

The program is very well designed, but the problem I have is that it is not possible to change my date of birth, which I entered incorrectly during registration, but it is possible to change my name and other details within the program.I sent a request by e-mail and also through the software itself, but unfortunately this has not been fixed yet. In my opinion, giving the possibility to change such things helps to improve the software a lot.

App is good. it's gains couple stars being German and offering English language. that is amazing. otherwise the navigation is okay. this is no reflection on the service behind the app which is a separate review. on service front, so far (touch wood) no issues
