LINK BAND / DEVELOPER TOOLS
Start with the signal,
build it into your app.
Connect LINK BAND EEG, PPG, and ACC data
to Web, Android, and iOS.
From an app to inspect signals to a service you build yourself.
Web · Android · iOS SDK / Free, including commercial use
01 / EXPLORE THE SIGNAL
LINK BAND SDK 2.0
Connect, view, and record.
Before you start building, meet the raw signals in the app.
One app, available on Google Play and the App Store.
- 01Connect directly to LINK BAND over BLE in the app
- 02View real-time EEG, PPG, and ACC waveforms
- 03Export recorded data as CSV or JSON
On iPhone, you can try demo mode without a device.
Signals shown are simulated demo data.
02 / BUILD WITH THE SDK
Start in an environment you know.
Choose a platform and connect the SDK.
Web, Android, and iOS are all free, including commercial use.
Android
Add the Maven Central dependency
to your app module's Gradle settings.

05 / GOOD TO KNOW
Frequently asked questions
Do I pair LINK BAND in my phone's Bluetooth settings first?
No. Do not pair it in your phone's Bluetooth settings. The app or SDK connects directly to LINK BAND over BLE.
Can I use the SDKs commercially?
The Web, Android, and iOS SDKs are free, including commercial use. Cloud services for analysis are subject to separate discussion.
Is measurement data sent externally?
Operation is offline, and measurement data is not transmitted externally.
Can I try the app without a device?
On iPhone, LINK BAND SDK 2.0 includes a demo mode you can try without a device.
Can I connect from iPhone Safari?
iPhone Safari does not support Web Bluetooth. View signals with the App Store app, or build directly with the iOS SDK.
LINK BAND provides SDKs for Web, Android, and iOS. The Web SDK connects directly to the device using Web Bluetooth in Chrome or Edge. iPhone Safari does not support Web Bluetooth, so iPhone users can use LINK BAND SDK 2.0 from the App Store or build an app with the iOS SDK. The Android SDK uses Kotlin, and the iOS SDK uses Swift. Data includes two-channel EEG at Fp1/Fp2 at 250 Hz (µV, raw values before filtering), PPG at 50 Hz, ACC at 30 Hz, and battery information. The Web, Android, and iOS SDKs are free, including commercial use. Cloud services for analysis are subject to separate discussion.
