Verdict
The clearest difference is review sentiment: PassGen at 100% against Logic Circuit Simulator's 21%. PassGen also leads on rating (4.7 vs 3.4) and update cadence (every 2 months vs every 6 months). Logic Circuit Simulator's advantage is ratings volume (46 vs 9) and iOS requirement (12.0 vs 15.2). On ads, in-app purchases and device support there is nothing between them.

PassGen costs $0.99 and Logic Circuit Simulator $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
PassGen holds the better App Store score, 4.7 against 3.4.

PassGen ships an update every 2 months, Logic Circuit Simulator every 6 months. Both last shipped on October 7, 2026.
