The official Blue TV app from Swisscom is not available directly via the Amazon Appstore for the Fire TV Stick 4K. Some users have installed the Android TV version manually, but this is not officially supported and can lead to compatibility issues. For reliable use, Swisscom recommends compatible Android TV devices such as the Google Chromecast with Google TV.

If you still want to test the app, you will need the APK file of the Android TV version and have to install it manually - this requires technical know-how and is not guaranteed to work. For official support, please contact Swisscom support or check their current device list.

*Note:* The Fire TV Stick 4K specifications (Fire OS, 8 GB memory, 4K playback) are basically powerful enough, but app compatibility depends on software availability.
