The ST BLE Sensor application is used in conjunction with an ST development board and firmware compatible with the BlueST protocol to give you access to all the sensor data, which you can log to different cloud providers, and to update the board firmware directly from a mobile device via the Bluetooth® Low Energy protocol. After discovery ST development board, the app shows you a list of available demos and you can navigate through them to discover the functionalities of your board. Demos can be related about environmental, cloud, audio, board configuration, machine learning and and many other functionalities. The application is built on top of the BlueST SDK library implementing the BlueST protocol and helps you export the data easily via Bluetooth® Low Energy. The application also supports firmware library algorithms like motion-sensor data fusion, activity recognition and pedometer functionality. Both SDK and application source code are freely available at: https://github.com/STMicroelectronics
IoT Toolbox

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
