System Guard is new from the ground up, rewritten for iOS 17 and later
Overview: live CPU, memory, storage and power, the thermal state, and whether a newer iOS is available for your exact model
Device: model, chip, GPU, memory, display, cameras, sensors, Face ID or Touch ID and more, grouped, with every value explained at a tap
Compare your device with other models of its kind, row by row - including the iPhone 18 Pro and iPhone 18 Pro Max
Network: connection, local and public IP addresses, Wi-Fi details, VPN, DNS servers, cellular technology (LTE, 5G), and your data traffic for today, yesterday, 7 days and 30 days
Speed and latency test with a progress bar and the current rate, and the devices on your local network (System Guard Pro)
