4 months ago 3

KFritz Version: 0.0.1

KFritz is a KDE Plasma 6 Plasmoid that connects to your AVM Fritz!Box and displays real-time incoming calls. It shows the caller name and number, maintains a history of recent calls, and integrates with the KDE notification system for alerts.

Designed for modern Plasma 6 environments, KFritz supports:

Real-time call monitoring via the FritzBox CallMonitor
Caller name resolution from the FritzBox phonebook via TR-064
Recent call history with timestamps
Compact and full Plasma representations
KDE notifications using KNotification
