System Guard Downloads & RevenueSystem Guard · App Store

Know your iPhone, iPad and Watch inside out. System Guard shows what your device is, how it is doing right now and whether anything needs your attention - in plain language, with every figure explained.

► AT A GLANCE

• Compare your device with any other iPhone or iPad

• Export a device report as PDF, text or JSON

► WIDGETS, CONTROLS, WATCH AND SHORTCUTS

• Control Center controls for the check-up and the speed test
• Apple Watch app with the watch's own figures, your iPhone's status and complications

► SYSTEM GUARD PRO
One purchase, no subscription. Removes all ads and unlocks History and alerts, the full check-up, the network details and the speed test, the devices on your network, the battery charts and full battery details, more devices in Battery health, iCloud sync, the device report, and every widget and Shortcut.

► PRIVACY
System Guard reads only what iOS makes available to every app, never changes anything on your device and needs no account. Your history and battery readings stay on your device, unless you sync the battery readings with your own iCloud, which only you can see. The free version shows ads; you can choose non-personalized ads at any time.
