At some point while being employed at that startup I could try the smell of being kind of a gun for hire when working on the app version of the surprisingly popular tv program website tvtv.de. The design is definitely dated but it gained its popularity in Germany by being fast and easily skimmable which should be translated into the mobile context and environment as well.
The focus is clearly on showing the current German tv program, secondarily at (also pretty German) prime times 20:15 and 22:00, front and center, with additional options to see recommendations by the editorial team and the channel browser.
Unfortunately the apps don't get updated anymore, so on iOS you need at least iOS 10 or below (untested on Android). But if you happen to get a chance to try the app, have a look at my favorite feature: the quite original »Other Time« skimmer. 😉
