Device Monitor Z: CPU x RAM OS

Device Monitor Z (also known as iDevice Monitor) is a comprehensive iOS app that surfaces real-time device stats across CPU/GPU, RAM, storage, battery, and OS information for iPhone, iPad, and iPod touch. It offers Home Screen and Lock Screen widgets for quick access to key data, along with basic device info like camera, display, and supported sensors.

Beyond monitoring, the app includes a full toolkit: performance benchmarks (CPU and disk), a robust network analyzer (SpeedTest, LAN Scanner, DNS lookup with DoH/DoT, traceroute, port scan, DNS speed tests, and Bonjour service discovery), as well as a Sensor Monitor (GPS, accelerometer, gyroscope, etc.), Screen Test, and export options (CSV, PDF, XLSX, JSON, RTF, TXT).
