# CERV vs Airthings

The clearest difference is review sentiment: CERV at 100% against Airthings's 33%. CERV also leads on rating (5.0 vs 4.4) and monetization model (free vs free with in-app purchases). Airthings's advantage is ratings volume (3K vs 3). 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.

CERV holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Airthings has 3K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 100% of CERV's written reviews are positive against 33% of Airthings's.
