Test your typing speed on both your laptop keyboard and mobile device.
After you give consent and choose your age group, the server will randomly assign you
a device order — phone→laptop or laptop→phone — independent of which device you’re using right now.
If this device isn’t first, we’ll show a link (and a QR on laptops) to open Phase 1 on your other device.
When Phase 1 finishes, this tab will automatically load Phase 2.
If this device is the first one in your assigned order, you’ll begin Phase 1 right here.
After completing Phase 1, you’ll receive a link (and QR if on a laptop) to continue Phase 2 on your other device.
No personal information is collected.
Please wait a moment.

If it doesn't submit, check for extra spaces or newlines at the end. You can refresh the page at any time to resume your progress.
