SDK

Connect measurement data to your own software

Choose the SDK for your operating system and build the device connection, data reception, and storage flow.

  • Android
  • iOS
  • Windows
  • Linux

Supported operating systems

Find the SDK package and documentation for Android, iOS, Windows, or Linux.

SDK for Android

Build device discovery, connection, and data reception into a Flutter-based Android app.

  • Android

SDK for iOS

Use the same signal-reception structure in a Flutter-based iOS app.

  • iOS

SDK for Windows / Linux

Deliver PPG and IMU streams to your own program in a Python environment.

  • Windows
  • Linux

How to use

Apply the SDK in four steps, from connection to storage

Use the README supplied with your SDK version for exact functions and initialization. This page explains the workflow shared across platforms.

  1. 01

    Discover and connect

    Enable Bluetooth and select a supported EmoConnect or VitalTrack device.

  2. 02

    Receive signals

    Receive PPG and nine-axis IMU data as streams on one timeline.

  3. 03

    Connect your program

    Pass received data to a research UI, service logic, or your own analysis code.

  4. 04

    Store and verify

    Save by session, then verify missing samples and time alignment under real measurement conditions.

Integration example

Use the received data in this structure

Align PPG and motion data on one timeline, then connect them to a live screen, event records, or CSV storage.

  • Synchronize PPG with accelerometer, gyroscope, and magnetometer data
  • Record study events such as baseline and task
  • Continue in existing tools such as Excel, Python, or MATLAB

Compare the data available with free and PRO access

Receive source signals with the free SDK, then review processed-waveform and additional-analysis scope for PRO.

Free

  • Four platforms — Android, iOS, Windows, Linux
  • Live raw PPG and IMU stream
  • Direct access to the raw signal
  • Build your own analysis pipeline

PRO only

  • Everything in the free tier
  • Plus the filtered waveform from Smart Noise Filtering

The filtered waveform is currently delivered by the Windows and Linux SDKs.
