# Vent vs ComfoControl

The clearest difference is rating: Vent at 5.0 against ComfoControl's 3.8. Vent also leads on update cadence (every 2 months vs every 4 months). ComfoControl's advantage is review sentiment (60% vs 20%) and ratings volume (6 vs 1). 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.

Vent holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: ComfoControl has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of Vent's written reviews are positive against 60% of ComfoControl's, so the app with the better star average is not the one people write more warmly about.

Vent ships an update every 2 months, ComfoControl every 4 months. Both last shipped on November 2, 2026.
