# Circuitry vs Smart Logic Simulator

The clearest difference is review sentiment: Circuitry at 96% against Smart Logic Simulator's 50%. Circuitry also leads on rating (4.8 vs 3.0) and in-app purchases (none vs 1). Smart Logic Simulator's advantage is update cadence (every 2 months vs every 46 months) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Smart Logic Simulator sells 1 one-off in-app purchase. 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 2, 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 50% of Smart Logic Simulator's.

Circuitry ships an update every 46 months, Smart Logic Simulator every 2 months. The most recent releases landed on September 18, 2026 and September 8, 2026 respectively.
