Verdict
The clearest difference is monetization model: dictionary.camera at free against Airthings's free with in-app purchases. dictionary.camera also leads on iOS requirement (13.0 vs 17.6). Airthings's advantage is ratings volume (3K vs 31) and update cadence (fortnightly vs monthly). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Airthings holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Airthings has 3K ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 36% of dictionary.camera's written reviews are positive against 33% of Airthings's, so the app with the better star average is not the one people write more warmly about.
dictionary.camera ships an update monthly, Airthings fortnightly. The most recent releases landed on October 3, 2026 and October 19, 2026 respectively.
