Paid plans add motors and control devices, fault practice, exam practice, saving online, your progress on your phone and computer, and tools for teachers."}},{"@type":"Question","name":"Do I need an account?","acceptedAnswer":{"@type":"Answer","text":"No. Open the simulator and start; your circuit stays in this browser until you share it. A pass needs no account either: pay now, and sign in later to use it on your other devices. You need an account for a subscription, and to keep circuits and course progress online."}},{"@type":"Question","name":"Does it work on a phone or tablet?","acceptedAnswer":{"@type":"Answer","text":"Yes. Devices, wires, and the simulation work by touch; a larger screen is more comfortable for big circuits."}},{"@type":"Question","name":"Can I use it with my class?","acceptedAnswer":{"@type":"Answer","text":"Yes. Share an exercise as a link, or start a follow-along session: the class joins with a short code and sees your canvas live."}}]}]}
