Why a physical keyboard matters
Touch typing is about muscle memory across the whole keyboard, so you learn fastest on real keys you can feel without looking. A standard desktop or laptop keyboard gives you that.
Tablets and phones
The site works on mobile screens, but an on-screen phone keyboard cannot teach true touch typing. If you use a tablet, pair it with a Bluetooth or attached keyboard for a proper practice setup. See using Meta Typing Club on mobile for details.
Browsers and school computers
Any modern browser works, including on Chromebooks and school lab machines. Check supported browsers and whether it works on Chromebooks and labs.
