It's great to know how logic gates work. I made a clock using 7 segments and mini Hz clocks

Very good simulation
Can you add default high input switch and also pull up/ down resistors?
Very good work
How long
It works well but there is no way of making things nice and tidy. It would be great if the connections could be routed by hand and have intersection nodes. Snapping to grid and being able to select multiple elements to move them would make this app perfect.

Classic logic gate sim. Had it for years and it never let me down

Can not save circuit
Amazing for little stuff, but I started to develop some bigger stuff like full CPUs. And it crashed and lost my work.
Very good app, nice to start learning the mechanics of logic gates, but it could go a lot further.

“Really good app, really intuitive and easy to learn, though I'd like to see the addition of variable screen ratios so I don't have a big black box at the bot…”
“Beautiful app!”
“Ik its alot but its ok if u added them 1 by 1, anyway, good app for technical/electrical engineering and overall fun”
