# ST BLE Sensor vs IoT Toolbox

The clearest difference is rating: IoT Toolbox at 4.0 against ST BLE Sensor's 2.0. IoT Toolbox also leads on iOS requirement (8.0 vs 15.0). ST BLE Sensor's advantage is ratings volume (10 vs 2). On price, review sentiment, update cadence and ads there is nothing between them.

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

IoT Toolbox holds the better App Store score, 4.0 against 2.0. That said, the two scores are not equally well evidenced: ST BLE Sensor has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 0% and 0% positive.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on June 19, 2026 and September 19, 2026 respectively.
