Both are free to download. Easy Ohm's Law sells 1 one-off in-app purchase. DC Circuit Builder asks for nothing beyond the download.
DC Circuit Builder holds the better App Store score, 2.6 against 1.5. That said, the two scores are not equally well evidenced: DC Circuit Builder has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 69% of Easy Ohm's Law's written reviews are positive against 50% of DC Circuit Builder's, so the app with the better star average is not the one people write more warmly about.
