Circuitry is a hands-on logic game that makes Boolean algebra, logic gates, and digital circuits easier to understand. Build circuits by connecting AND, OR, XOR, NOT, and other gates, then experiment with different inputs to see how signals travel through your design. Work through 22 progressively challenging problems to unlock new components. Then use Playground Mode to create and test circuits of your own. Features: - 22 logic-circuit problems - Interactive circuit building and simulation - 36 different circuit components - Playground Mode for creating your own circuits
TNK Scope

Verdict
The clearest difference is update cadence: TNK Scope at every 2 weeks against Circuitry's every 46 months. TNK Scope also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
