The short answer
Yes. The labs run on phones, tablets and laptops in a recent Chrome, Edge, Firefox or Safari. A laptop or large tablet is easier for wiring and ladder logic, because you have more room.
Which device?
Are you wiring or writing ladder logic?
Yes
Use a laptop or large tablet if you can.
No, just looking around
A phone is fine.
Nothing is installed. The labs use your browser's 3D support.
Which browsers
A recent version of Chrome, Edge, Firefox or Safari.
Phones and tablets
The labs run on phones. For wiring and ladder logic a laptop or large tablet is better, because you have more room and a keyboard. The 3D halls look best on a laptop.
