# Circuitry vs Logic

The clearest difference is ads: Circuitry at none against Logic's shown. Circuitry also leads on review sentiment (51% vs 21%) and rating (3.9 vs 3.6). Logic's advantage is update cadence (every 5 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Circuitry holds the better App Store score, 3.9 against 3.6. That said, the two scores are not equally well evidenced: Circuitry has 155 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 51% of Circuitry's written reviews are positive against 21% of Logic's.

Circuitry ships an update every 4 months, Logic every 5 weeks. The most recent releases landed on October 17, 2026 and October 12, 2026 respectively.
