iCircuit VS LibrePCB

For a nice, polished, non-skeuomorphic circuit simulator, see iCircuit [1], which provides native MacOS and iOS clients (based on the Falstad JS circuit simulator mentioned elsewhere in this thread, if I recall correctly). It differs from most SPICE-based simulators in that there is no edit or run mode - the circuit is always simulating in transient mode so updates happen in real time.

On the open source front, LibrePCB seems to be the only contender, never used it myself, but have heard good things and met some devs at a conference and they were nice. The level of support you get there may be a bit more personal. Otoh, if you've never designed PCBs before, it may be hard to even tell if something is a bug... Source: 11 months ago

I would throw LibrePCB into the mix. Coming from Eagle, it was easier for me to grasp than KiCad. Source: 12 months ago

Also LibrePCB at https://librepcb.org A bit "lighter" in size than KiCad. Source: about 2 years ago

I've been turning out some nice results from LibrePCB. It has a learning curve like anything else but its not an impossibly convoluted workflow like some of the more established FOSS programs out there. Source: over 2 years ago
