# Atmosphere vs Bat Detector

The clearest difference is rating: Bat Detector at 5.0 against Atmosphere's 4.1. Bat Detector also leads on in-app purchases (none vs 1) and update cadence (monthly vs every 3 months). Atmosphere's advantage is review sentiment (67% vs 40%) and ratings volume (72 vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Atmosphere sells 1 one-off in-app purchase. Bat Detector asks for nothing beyond the download.

Bat Detector holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Atmosphere has 72 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 67% of Atmosphere'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.

Atmosphere ships an update every 3 months, Bat Detector monthly. The most recent releases landed on September 5, 2026 and September 2, 2026 respectively.
