# ExView® vs Airthings

The clearest difference is rating: ExView® at 5.0 against Airthings's 4.4. ExView® also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 17.6). Airthings's advantage is update cadence (fortnightly vs every 6 months) and ratings volume (3K vs 1). 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.

ExView® 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 1, so its average is the more settled of the two.

ExView® ships an update every 6 months, Airthings fortnightly. The most recent releases landed on September 8, 2026 and September 25, 2026 respectively.
