# Radon Eye Plus vs Renogy

The clearest difference is ratings volume: Renogy at 806 against Radon Eye Plus's 4. Renogy also leads on rating (3.8 vs 3.5). Radon Eye Plus's advantage is review sentiment (33% vs 11%) and iOS requirement (9.0 vs 13.0). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Renogy holds the better App Store score, 3.8 against 3.5. That said, the two scores are not equally well evidenced: Renogy has 806 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 33% of Radon Eye Plus's written reviews are positive against 11% of Renogy's, so the app with the better star average is not the one people write more warmly about.

Radon Eye Plus ships an update monthly, Renogy every 2 weeks. The most recent releases landed on October 19, 2026 and October 20, 2026 respectively.
