Description

Easy calling with the landline network

Make calls at home conveniently using your smartphone over your landline telephone numbers - anywhere in the Wi-Fi network of your FRITZ!Box. With the FRITZ!App Fon you benefit from the landline rates; for many providers even from flat rate telephony. HD telephony provides for crystal clear voice quality. Thanks to support for Bluetooth headsets you can enjoy complete flexibility for everyday calling and for working from home. The latest technologies mean that the FRITZ!App Fon works invisibly in the background no matter what the battery status.

The FRITZ!App Fon guides you through the easy Configuration. Simply log in by entering your FRITZ!Box password, selecting one of your landline telephone numbers, and them confirm: your smartphone is ready for landline telephony. Once it has been configured, the FRITZ!App Fon makes your smartphone ring immediately for incoming calls, just as if it were a FRITZ!Fon, the intelligent all-rounder for your home network with FRITZ!. Incoming calls ring simultaneously on your telephones and smartphones. You decide which device should pick up the call. If you would like your smartphone to ring only for certain landline telephone numbers, select only these numbers in the settings of FRITZ!App Fon.

The FRITZ!App Fon is the ideal telephony extension for your FRITZ!Box. Be it a handset for the new roommate in your shared apartment, an additional telephone for working from home, or the convenience of the smartphone that's always handy: with the FRITZ!App Fon you always have a practical solution in no time at all. It is easy to use the FRITZ!App Fon on multiple smartphones.

Comments on FRITZ!App Fon for Android

★★★★☆ Rob Noble · Jan 20, 2026

This works reasonably well – call quality is OK, there's a bit of lag compared to a DECT handset but not too much, and it even works away from home when my mobile is connected via Wireguard VPN back to the router (an unexpected bonus). One improvement I would like to see would be to separate the incoming call reject button into two: reject the call, or stop ringing but leave the call ringing on other handsets. Buttons to divert calls to a configured answering machine would be useful too.

★★★★☆ Steven Denny · Jun 24, 2022

Great app. One minor niggle it only seems to give the caller's number even though there's a contact with that number in both the fritz box and the phone

★★★★☆ Arne Aerts · Aug 19, 2022

UI looks good and app is does what it supposed to do, except vibrate. No matter which ringtone, or silent/sound mode I use, my S20 will not vibrate. Normally I always use my phone in silent mode, so this basically means I miss 100% of the calls. I have contacted AVM in-app ask they asked but have not heard from them since. I will update my review if I ever do. EDIT: Cs got back to me and after a reinstallation and some changed settings, vibrations are coming through.

★☆☆☆☆ Hartmutux Stonehenge · Jan 21, 2025

All newer version than 1.90.10 set the screen dark permanently (not only during the call), so it renders the phone unusable (no change with taps or the phones power-on button) -- Android 11 N105G. Only solution is to power off and reboot the phone in blind flight. The newer versions are missing the 'Advanced settings' where it was possible to keep the screen on during calls ('reduce display brightness' -- that prevented turning off the display).

★☆☆☆☆ Gaspard Gendreau · Nov 21, 2022

Incoming calls are no longer ringing on several of recent and new Samsung we have in the family (S9, S10, S22, A31,...). But still works on a 9 years old Samsung. These apps becomes almost useless

Can only add my fritz box by ip, to then complain my lets encrypt certificate does not match

★☆☆☆☆ Dennis Schridde · Jun 17, 2022

Since a while, when the app rings, and I pick up (green "answer" button), it shows the screen that it shows when in a call, but the app keeps ringing, and I am not actually in a call with the caller. Tapping the red "hang up" button has no effect. There is no way to get out of the "call" or to make the ringing stop, apart from force-stopping the app via Android settings. FRITZ! App Fon is basically unusable like this.
