Verdict
The clearest difference is rating: Airthings at 4.4 against Radon Eye Plus's 3.5. Airthings also leads on ratings volume (3K vs 4) and update cadence (fortnightly vs monthly). Radon Eye Plus's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (9.0 vs 17.6). On price, review sentiment, ads and in-app purchases there is nothing between them.
