# UTM SE vs Razer Cortex Mobile

The clearest difference is rating: Razer Cortex Mobile at 4.6 against UTM SE's 3.8. Razer Cortex Mobile also leads on in-app purchases (none vs 3) and update cadence (every 2 months vs every 4 months). UTM SE's advantage is review sentiment (55% vs 35%) and device support (4 vs 2). On price and ads there is nothing between them.

Both are free to download. UTM SE sells 3 one-off in-app purchases. Razer Cortex Mobile asks for nothing beyond the download.

Razer Cortex Mobile holds the better App Store score, 4.6 against 3.8. That said, the two scores are not equally well evidenced: Razer Cortex Mobile has 3.5K ratings behind it against 562, so its average is the more settled of the two. Written reviews complicate that: 55% of UTM SE's written reviews are positive against 35% of Razer Cortex Mobile's, so the app with the better star average is not the one people write more warmly about.

UTM SE ships an update every 4 months, Razer Cortex Mobile every 2 months. Both last shipped on October 30, 2026.
