Kyto with finger sensor

The Kyto is a small device that has a heart rate sensor and that you can connect to an app via Bluetooth. This Kyto comes with a fingertip sensor and a USB charging cable.

It is a very handy biofeedback device that is easy to connect to your Android smartphone, iPhone, iPad or iPod. You place the index finger in the infrared finger sensor, which uses Bluetooth and an app to provide an efficient layout where you can read your coherence level.

The Kyto is available in three colors: blue, red or black.

Also available is a handy pouch to keep the Kyto and the included cables safe. Price is 5 €. See pictures. You can also order the travel pouch separately.

Good to know:

  • Before you use the Kyto first: charge it for 2 hours via the supplied USB cable, connected to your laptop or computer. Do not charge via the electrical network as the batteries are very sensitive and cannot tolerate high current voltage. your battery will not last long or even become defective.
  • Sometimes you may notice that it is very difficult to connect via bluetooth. Turning on both location and bluetooth can help. Please note, the Kyto only matches with bluetooth 4.1 and higher. So check this on your smartphone if you have difficulties with your connection.
  • After use, it is best to always disconnect the ear sensor from the Kyto. If you don’t do this, the Kyto will continue to consume battery.
  • If the ear clip sensor is attached with the cable in the Kyto and the clip on the earlobe, a small red light on the Kyto should flash regularly. If this is not the case, the clip is not properly attached.
  • Do not start the measurement in the app until you have a constantly flashing light.
  • If you have problems exercising, this may be due to poor blood flow in the earlobe. In this case, a finger sensor can offer you relief. Or use the ear sensor on your finger if possible! 🙂
  • Avoid using sensors in direct sunlight. The sensors are confused by this bright light.

The Coherence Heart Trainer

There are several apps you can use with the kyto. One of the apps is Coherence Heart Trainer.

First you purchase the Kyto and then you go to the Appstore to download the “Coherence Heart Trainer” App. This app shows you the HRV (Heart Rate Variability) on your smartphone.

When ordering the Kyto, I will also provide you with a Dutch manual for connecting the Coherence Heart trainer app to the kyto.
