# Logic vs Smart Logic Simulator

The clearest difference is in-app purchases: Logic at none against Smart Logic Simulator's 1. Logic also leads on rating (3.3 vs 3.0) and ratings volume (6 vs 2). Smart Logic Simulator's advantage is ads (none vs shown) and review sentiment (50% vs 21%). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Smart Logic Simulator sells 1 one-off in-app purchase. Logic asks for nothing beyond the download.

Logic holds the better App Store score, 3.3 against 3.0. Both are backed by a comparable volume of ratings — 6 and 2 respectively. Written reviews complicate that: 21% of Logic's written reviews are positive against 50% of Smart Logic 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, Smart Logic Simulator every 2 months. The most recent releases landed on October 2, 2026 and September 24, 2026 respectively.
