As a native English speaker who is learning German, this app makes it pretty easy. Dealing with health issues is never a good time to be learning a language. The fact that most of the documents and screens are in English It's very helpful. Much better than the service and app I was using from other German insurance companies that I have used previously, they were Not-A-OK.

For very simple stuff no problem. But sending documents is very difficult. They don't really like PDFs, only JPEGs. English is the only second language option and even then, the English settings are very rudimentary. I still end up having to call and send documents by post. not even email seems to be an option. On the phone they will suggest sending a FAX like it's 1972 or something.

I like TK as a health insurance provider (one of the few services in Germany that actually works, and works well), but the app is terrible. Initial login has to be done with a code from a letter. At some point, it decided that my phone was no longer secure enough to allow me to log in using my fingerprint. Now it's started crashing due to some unknown error. Nah, I'll go back to using the web version instead.
