FRITZ!App Fon connects with your FRITZ!Box via WLAN so that you can use your telephone at home via the fixed-line network and the Internet. Once FRITZ!App Fon has been started, it automatically runs in the background, making it easy to take incoming calls while other apps are running, or even during standby operation.

Once FRITZ!App Fon has been started, you can make calls with your iPhone, iPod or iPad directly over your FRITZ!Box, just like with a cordless handset. Incoming calls are displayed automatically. To make an outgoing call, open FRITZ!App Fon and dial the desired telephone number via the telephone book. To listen to new messages on the FRITZ!Box answering machine, press and hold down the "1" key.

System requirements:
- FRITZ!Box with FRITZ!OS 7 or later
- iOS 10 or later

app collects info by default, no permissions asked

This app collects by default all possible information. The option to turn it off is buried deep inside in menus. This clearly violates all GDPR normatives that oblige you first to ask my permission for information collection.
