# IoT OnOff vs Bluetooth BLE Device Finder

The clearest difference is rating: Bluetooth BLE Device Finder at 4.4 against IoT OnOff's 3.5. Bluetooth BLE Device Finder also leads on ratings volume (27K vs 14). IoT OnOff's advantage is update cadence (every 3 weeks vs every 2 months) and review sentiment (48% vs 39%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. IoT OnOff sells 3 one-off in-app purchases and Bluetooth BLE Device Finder sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Bluetooth BLE Device Finder holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: Bluetooth BLE Device Finder has 27K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 48% of IoT OnOff's written reviews are positive against 39% of Bluetooth BLE Device Finder's, so the app with the better star average is not the one people write more warmly about.

IoT OnOff ships an update every 3 weeks, Bluetooth BLE Device Finder every 2 months. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
