# UAFX Control vs Cortex Studio

The clearest difference is rating: Cortex Studio at 2.7 against UAFX Control's 2.1. Cortex Studio also leads on ads (none vs shown) and update cadence (daily vs every 3 weeks). UAFX Control's advantage is ratings volume (19 vs 3) and review sentiment (9% vs 0%). On price 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.

Cortex Studio holds the better App Store score, 2.7 against 2.1. That said, the two scores are not equally well evidenced: UAFX Control has 19 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 9% of UAFX 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.

UAFX Control ships an update every 3 weeks, Cortex Studio daily. The most recent releases landed on September 27, 2026 and August 31, 2026 respectively.
