ST BLE Sensor vs PC/SC BLE
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
ST BLE Sensor
This app connects to ST development boards via Bluetooth Low Energy to access sensor data. You can log data to cloud providers, update board firmware, and explore various demo functionalities like environmental sensing and machine learning.
- Access sensor data
- Log data to cloud
- Update board firmware
- Explore demo functionalities
- Bluetooth Low Energy communication
- Motion-sensor data fusion

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
PC/SC BLE
This application allows users to interact with smartcard and NFC/RFID readers via a Bluetooth Low Energy connection. It supports retrieving smartcard ATR, exchanging APDUs, and reading/writing NFC tags. Developers can use the provided source code to build their own iOS applications.
- Bluetooth Low Energy connection
- Smartcard and NFC/RFID reader support
- Retrieve smartcard ATR
- Exchange ISO 7816 APDUs
- Read/write NFC tags
- Access to source code for development

SpringCard PC/SC over BLE is the reference application to work with SpringCard smartcard and NFC/RFID readers over a Bluetooth Low Energy connection. Use this application together with Puck Blue, or another BLE-enabled SpringCard smartcard reader. Connect to a contact or contactless smartcard, retrieve its ATR, exchange ISO 7816 APDUs; read/write NFC tags or RFID@13.56MHz labels; explore and validate your own use cases. Once ready, download the complete source code from GitHub ios-pcsclike-sample-ble project, and start developing your own iOS application together with SpringCard products!

Verdict
The clearest difference is rating: PC/SC BLE at 5.0 against ST BLE Sensor's 2.0. ST BLE Sensor's advantage is update cadence (every 2 months vs every 6 months) and ratings volume (10 vs 1). On price, ads, in-app purchases and monetization model 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.
PC/SC BLE holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: ST BLE Sensor has 10 ratings behind it against 1, so its average is the more settled of the two.
ST BLE Sensor ships an update every 2 months, PC/SC BLE every 6 months. The most recent releases landed on June 19, 2026 and July 5, 2026 respectively.
