# Radiacode vs Bat Detector

The clearest difference is rating: Bat Detector at 5.0 against Radiacode's 4.2. Bat Detector also leads on iOS requirement (15 vs 17.0). Radiacode's advantage is review sentiment (63% vs 40%) and ratings volume (93 vs 2). 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.

Bat Detector holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Radiacode has 93 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of Radiacode's written reviews are positive against 40% of Bat Detector's, so the app with the better star average is not the one people write more warmly about.

Radiacode ships an update every 2 months, Bat Detector monthly. The most recent releases landed on September 8, 2026 and September 2, 2026 respectively.
