# Logic vs Chip Simulator

The clearest difference is price: Logic at Free against Chip Simulator's $0.99. Logic also leads on rating (3.3 vs 1.0) and update cadence (every 5 weeks vs every 3 months). Chip Simulator's advantage is ads (none vs shown) and review sentiment (38% vs 21%). On ratings volume, in-app purchases and device support there is nothing between them.

Logic is free to download; Chip Simulator costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Logic holds the better App Store score, 3.3 against 1.0. Both are backed by a comparable volume of ratings — 6 and 7 respectively. Written reviews complicate that: 21% of Logic's written reviews are positive against 38% of Chip Simulator's, so the app with the better star average is not the one people write more warmly about.

Logic ships an update every 5 weeks, Chip Simulator every 3 months. The most recent releases landed on June 5, 2026 and September 8, 2026 respectively.
