Verdict
The clearest difference is monetization model: PRO at free against RadonEye's paid. PRO also leads on update cadence (monthly vs every 3 months). RadonEye's advantage is review sentiment (20% vs 4%) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
