# Circuitry vs Avionics Pro

The clearest difference is review sentiment: Avionics Pro at 100% against Circuitry's 51%. Avionics Pro also leads on rating (5.0 vs 3.9). Circuitry's advantage is ratings volume (155 vs 2) and iOS requirement (12.0 vs 16.0). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Avionics Pro holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: Circuitry has 155 ratings behind it against 2, 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 100% of Avionics Pro's.

Circuitry ships an update every 4 months, Avionics Pro every 5 months. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
