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

Verdict
The clearest difference is price: Circuitry at Free against Digital Gate Circuit Simulator's $7.99. Circuitry also leads on rating (4.8 vs 3.6) and review sentiment (96% vs 69%). Digital Gate Circuit Simulator's advantage is update cadence (weekly vs every 46 months) and device support (3 vs 1). On ads, in-app purchases and monetization model there is nothing between them.
