# Attenuator vs BLE

The clearest difference is rating: Attenuator at 5.0 against BLE's 3.0. Attenuator also leads on update cadence (every 7 months vs every 64 months) and ratings volume (8 vs 1). BLE's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On price and ads there is nothing between them.

Both are free to download. Attenuator sells 1 one-off in-app purchase. BLE asks for nothing beyond the download.

Attenuator holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Attenuator has 8 ratings behind it against 1, so its average is the more settled of the two.

Attenuator ships an update every 7 months, BLE every 64 months. The most recent releases landed on September 14, 2026 and September 17, 2026 respectively.
