Verdict
The clearest difference is rating: TechSheet at 5.0 against Airthings's 4.4. Airthings's advantage is in-app purchases (none vs 2) and ratings volume (3K vs 2). On price, ads, monetization model and device support 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. TechSheet sells 2 in-app purchases, starting at $4.99 per month. Airthings asks for nothing beyond the download.
TechSheet 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 2, so its average is the more settled of the two.
Airthings ships an update fortnightly, TechSheet every 5 weeks. The most recent releases landed on October 12, 2026 and October 1, 2026 respectively.
