Verdict
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.
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. 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.
