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.
