iCircuit

iCircuit is for people who want to sketch and inspect electronic circuits on a phone or tablet without dragging out paper and components. Its strength is the obvious one for this kind of app: you can build a circuit, see how parts connect, and use the device as a compact workspace for electronics ideas. The trade-off is that a screen will never feel as roomy as a bench, and detailed circuit work can get cramped fast. In practice, that makes the app useful for learning, quick experiments, and checking a design before it grows into something bigger. By our assessment, it sits in the practical middle ground between a toy simulator and the heavier desktop tools, and the interface has to do a lot of the thinking for you.
