How many users can use one app? Can I use with my whole family, for example?
At the moment one app is for one user only.

The app is crashing – what to do?
• You may have too many apps opened on your iPhone which will always slow down the processing power of your iPhone. Switch off some apps and then restart iTHRVE again.
• Do you have the latest version of iOS? If not, update your iOS.
• Check the compatibility – see above.
• If you’re using the iHealth sensor and the app is crashing it’s probably due to poor wifi/internet connection.

What kind of sensors can I use withe the iTHRVE app?
This HRV app has been designed to work with different sensors:
• iOS Camera (on your iPhone or iPad)
• Polar chest strap – for example Polar H7 chest strap

Polar H7 Bluetooth Chest Strap

Polar H7 Bluetooth Chest Strap

• Earclip Bluetooth sensor – for example Mobile Phone Heart Rate Monitor with Ear Clip

Mobile Phone Heart Rate Monitor with Ear Clip Sensor

Mobile Phone Heart Rate Monitor with Ear Clip Sensor


• Berry BM1000C (Working with the latest update of  iTHRVE apps)

Berry BM1000C PPG Finger Clip

PPG Mobile Phone Heart Rate Monitor Finger clip Sensor

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 iHealth finger sensor.
The light sensors devices (iHealth 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.
