A fast, accurate, and privacy-first utility that shows everything you want to know about your Apple devices. This tool has the most complete information available. By downloading, you are supporting a small independent open source developer who makes this information freely available to everyone and keeps it updatable by everyone. What you get: • Detailed hardware and software information including model, chip, storage, memory, introduction date, and minimum and maximum OS versions. • Battery information showing level and charge status. • Thermal indicator to recognize device temperature. • Orientation and display data showing how the system reports screen state. • Idle timer control to prevent the screen from dimming or locking when needed. • Device capabilities and sensors such as biometrics, LIDAR, ECG, Fall Detection, Oxygen Sensor, and more. • Direct support and reference links to Apple documentation based on your exact device. Why you’ll love it: • Privacy-first design with no data collection. All device information stays on your device. • Lightweight and fast with minimal battery or resource usage. • Continuously updated with new Apple devices, sensors, and operating system support. • Ideal for developers, IT support, and anyone who wants to know the exact capabilities of their Apple devices. This is a tool for exposing the information in the open source Kudit Device framework.
