Device Kit: CPU x RAM Monitor

Summary

Device Kit is an iOS system monitoring tool providing real-time CPU temperature, network speed, memory, battery, and charging power detection, featuring Dynamic Island live updates, floating widgets, and 18 practical tools to help users fully understand iPhone performance and health.

What is Device Kit?

Device Kit is a device health monitoring app designed for iPhone and iPad, offering real-time CPU temperature estimation (with 6-level thermal warning), CPU usage (user/system/idle breakdown), Wi-Fi and cellular network speed, battery status (charge level, charging state, low-power mode, thermal status), memory and storage usage. Supports Dynamic Island live monitoring, Picture-in-Picture floating widget, charging power detection (slow/standard/fast/ultra-fast tier), and charging history log. Includes 18 tools across system, network, utility, sensor, display, and environment categories: flashlight (9 blink modes), haptic feedback, multi-touch test, motion tracker, Ping, Telnet, SSH (Pro), QR code generator, decibel meter, password generator, compass, GPS, gyroscope, magnetometer, barometer, altimeter, proximity sensor, color & brightness adjustment, weather (Pro). Provides home screen widgets (uptime, weather, CPU, temperature, memory, storage, clock, device info, quick actions) and lock screen widgets (weather, storage, uptime).
