# Robotics U vs Circuitry

The clearest difference is update cadence: Robotics U at every 11 days against Circuitry's every 4 months. Robotics U also leads on review sentiment (67% vs 51%) and iOS requirement (9.0 vs 12.0). Circuitry's advantage is rating (3.9 vs 3.6) and ratings volume (155 vs 16). On price, ads, in-app purchases and monetization model 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 16, so its average is the more settled of the two. Written reviews complicate that: 67% of Robotics U's written reviews are positive against 51% of Circuitry's, so the app with the better star average is not the one people write more warmly about.

Robotics U ships an update every 11 days, Circuitry every 4 months. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
