Verdict
The clearest difference is rating: RadonPRO at 5.0 against Airthings's 4.4. RadonPRO also leads on monetization model (free vs free with in-app purchases) and iOS requirement (15.6 vs 17.6). Airthings's advantage is ratings volume (3K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
