ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
