The 2.2 release adds support for React Native, enabling easy cross-platform integration in that environment.



  • React Native SDK
  • SDK now enables the measurement to start in lower-FPS scenarios
  • SDK on Android will now request camera permissions if they are not already granted


The 2.1 release focuses on the web-on-mobile usage scenario, significantly increasing the SDK's performance and stability in that environment.



  • fix for initialization settings sometimes not being fully applied
  • support for some older Android devices with reduced camera capabilities
  • workaround of a WebKit issue that could prevent the Web SDK from loading on iOS browsers



  • InitializationSettings are now available in the Web SDK
  • missing initialization settings added for Android and iOS
  • fix a deinitialization issue on iOS that could arise if the embedded UI view was removed before the SDK was deinitialized



The 2.1.0 release focuses on the web-on-mobile usage scenario, significantly increasing the SDK's performance and stability in that environment.



  • a 'Device Unstable' icon now appears in the UI when the signal quality is disrupted due to the device/user movement
  • that state is also available programistically as runningSignalBadDeviceUnstable in the SDK API
  • the embedded UI scales better if the <canvas> element on which it is rendered is small
  • workaround for a bug present in Safari, increasing the amount of times the SDK can be reloaded in the same browser tab before running out of memory


  • fix for a condition with the embedded UI that could occur when deinitializing and initializing the SDK again


  • additional messages are now displayed on the default <canvas> before the Web SDK loads fully to indicate the progress
  • if the SDK cannot keep up with the real-time computations, a 'CPU on fire' icon appears, the measurement is aborted and blocked from starting for the next 5 seconds
  • the computational overload can be detected programistically as a new OperatingMode (SystemOverloaded) in the SDK API
  • performance improvements
  • bug fixes


  • Health Risks available in the Swift iOS API of the SDK


  • further performance improvements in the computational pipeline
  • fixes for some web-on-mobile specific issues
  • support for the Web version on iOS 17
  • automatic Wake Lock during the measurement in the Web version
  • web version loading progress indicator
  • fix for Camera Swap in the Web version


  • performance improvements in some parts of the computational pipeline
  • performance improvements in SDK's embedded UI rendering


The 2.0 release of the SDK brings a redesigned API surface and a fully integrated measurement UI/UX



  • further performance improvements in some parts of the pipeline
  • SDK size reduction
  • fix for iOS Flutter SDK


  • Swift/Objective-C API wrapper for the iOS SDK
  • support for Per-user (automatic) licensing model


  • performance improvements in some parts of the pipeline
  • fix for iOS camera not deinitializing properly at SDK deinitialization


  • fix new presets not available in Android Flutter plugin


  • two new unvalidated measurement presets have been added (FourtyFiveSecondsUnvalidated and ThirtySecondsUnvalidated) which allow for shorter measurements (45 and 30 seconds respectively)


  • slightly improved rPPG signal quality/rejection rate when the user is further away from the camera
  • added getSignalQualityMapPng method, which returns a PNG image with the signal quality map
  • added getFaceTexturePng method, which returns a PNG image with the region of the face used for the PPG signal extraction
  • added getFullPpgSignal method which returns a PPG signal after the measurement has concluded


  • lower signal quality threshold for the Relaxed measurement mode


  • added getCurrentSignalQualityMetric method to the SDK API
  • added average_signal_quality to the measurement results
  • updated Blood Pressure inference model
  • Fully integrated measurement UI/UX.




  • Interbeat intervals available after the measurement has concluded
  • Cardiovascular health risks calculation



  • [iOS] missing MinimumOSVersion information added to file



  • [iOS] fix for a possible crash when deinitializing the SDK and initializing it again
