Verdict
The clearest difference is rating: Cortex Studio at 5.0 against Ampero Control's 1.9. Cortex Studio also leads on update cadence (daily vs every 14 months). Ampero Control's advantage is monetization model (free vs freemium) and ratings volume (61 vs 1). On price, ads, 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.
Cortex Studio holds the better App Store score, 5.0 against 1.9. That said, the two scores are not equally well evidenced: Ampero Control has 61 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 13% of Ampero Control's written reviews are positive against 0% of Cortex Studio's, so the app with the better star average is not the one people write more warmly about.
Ampero Control ships an update every 14 months, Cortex Studio daily. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
