Install DeviceTestHub on your device
Add DeviceTestHub to your home screen for a faster, app-like experience. Steps vary by browser.
Chrome or Edge (Android, Windows, ChromeOS)
When available, an Install card appears at the bottom of the screen. Tap it and confirm. You can also open the browser menu and choose Install app or Add to Home screen.
Safari (iPhone or iPad)
Tap the Share button, then Add to Home Screen. Safari does not show an automatic install prompt, so this manual step is required on iOS.
Firefox
Firefox supports installable web apps via the address-bar install icon (desktop) or the page menu. On some platforms an automatic prompt may not appear; use the browser menu to add it to your applications or home screen.
Already installed?
If you opened this from your home screen, you're already running the installed app. Hardware tests still require a real device and browser permission prompts, online or offline.
