# PRO vs Breeze Radon

The clearest difference is review sentiment: Breeze Radon at 100% against PRO's 30%. PRO's advantage is rating (4.9 vs 4.0) and ratings volume (114 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PRO holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: PRO has 114 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 30% of PRO's written reviews are positive against 100% of Breeze Radon's, so the app with the better star average is not the one people write more warmly about.

PRO ships an update every 2 weeks, Breeze Radon every 3 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
