Worked example
Pressing Generate on a phone-sized screen lists its screen size, pixel ratio, touch support and orientation, and the tap area counts each tap on that same device.
What this tool does not do / Limits
This tool only tests the device and browser running this page. It does not test, connect to or diagnose a remote iPhone, and it cannot fix hardware problems.
Frequently asked questions
Does this test a real iPhone somewhere else?
No. It reports the screen and browser details of the device you are using right now, so run it on the iPhone itself to see that device.
What does the tap area check?
It counts taps or clicks on this device, as a simple check that touch or pointer input reaches the page.
