Verdict
The clearest difference is rating: RadonEye at 2.3 against PRO's 1.0. RadonEye also leads on ratings volume (52 vs 1) and review sentiment (20% vs 4%). PRO's advantage is monetization model (free vs paid) and update cadence (every 5 weeks vs every 3 months). On price, ads, in-app purchases and device support there is nothing between them.
