# Logic vs Circuit Snap

The clearest difference is in-app purchases: Logic at none against Circuit Snap's 1. Logic also leads on review sentiment (21% vs 0%) and device support (3 vs 1). Circuit Snap's advantage is ads (none vs shown) and iOS requirement (12.2 vs 15.1). On price, rating and update cadence there is nothing between them.

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

Circuit Snap holds the better App Store score, 3.5 against 3.3. 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 0% of Circuit Snap'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, Circuit Snap monthly. The most recent releases landed on June 5, 2026 and September 11, 2026 respectively.
