Website Speed is the application meant to test the speed of your own web sites on real devices and which does not use an external cloud computing.
The tests are performed using the real skills of the device, of the browser and of the Internet connection which is available at the moment.
Furthermore, the application uses the device API and therefore it tries to obtain values, which are as similar as possible to those obtained through a normal Internet navigation.
This app has been updated by Apple to use the latest Apple signing certificate.
With Family Sharing set up, up to six family members can use this app.
