Verdict
The clearest difference is rating: RadonPRO at 5.0 against RadonEye's 2.4. RadonPRO also leads on monetization model (free vs paid) and update cadence (every 3 weeks vs every 3 months). RadonEye's advantage is ratings volume (47 vs 1) and iOS requirement (13.0 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
