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
LogicGate

Verdict
The clearest difference is review sentiment: Circuitry at 96% against LogicGate's 0%. Circuitry also leads on rating (4.8 vs 3.0) and in-app purchases (none vs 2). LogicGate's advantage is update cadence (fortnightly vs every 46 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. LogicGate sells 2 in-app purchases, starting at $4.99 per 7 days. Circuitry asks for nothing beyond the download.
Circuitry holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: Circuitry has 291 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 96% of Circuitry's written reviews are positive against 0% of LogicGate's.
Circuitry ships an update every 46 months, LogicGate fortnightly. The most recent releases landed on September 18, 2026 and September 24, 2026 respectively.
