    On this page, you’ll find links to pages and manuals for the iTHRVE app and how to use different transducers: camera light vs chest strap vs finger clip vs ear clip.

    iTHRVE works on the latest version of iOS, iPhone 5, iPhone 6 and iPod touch 5 and the latest versions of iPads. iTHRVE doesn’t work on previous versions of iPhones, iPod touch.

    This HRV app has been designed to work with different sensors:
    • iOS Camera (on your iPhone)

    All of these sensors can be used for short recording (less than 30 minutes): mainly designed for coherence and breath training.
    Long recording (up to 8 hours and a half), can only be done with the use of a Polar chest strap or a compatible Bluetooth chest strap device.

    The pressure wave (related to the Mayer wave or Craniosacral wave) can only be displayed with the finger sensor.
    The light sensors devices (finger sensor, the earclip sensor and the iOS camera) are very sensitive to movements of the sensor: they need you to be quite still- when used to achieve a good acquisition of data.
