Useless. Has you jump through several hoops incl requesting a code by letter from the app, only to tell you *after* that needlessly tedious process that the app won't run on your device, because it is rooted - spoiler: it isn't! - because of "data security". I don't think you even know what that is, you still use smsTAN instead of a professional aurhenticator! Badly done, badly tested and a waste of time.

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.

Wenn Sie Unterstützung brauchen, kontaktieren Sie gern unseren Support unter tk.app@tk.de. Viele Grüße, Ihre TK-App

App GUI is good, you get access to many things in the app. Most importantly, the app has many problems with reading the cycling data from google fit. No matter if you record the data in google fit itself or import from other apps and devices, it is designed to fail your TKFit challenge if you consider doing the challenge with cycling. the customer service also does not help adding the data after complaining.
