Designed to encourage relaxation, this device puts fresh air into your lungs by helping you take deeper breaths. Featuring a rounded and smooth shape, Kitoki is enjoyable to hold in your hand. Likewise, the little buttons show you exactly where to place your fingers.
Once you have a comfortable grip, put your mouth on the mouthpiece and take a deep breath. Additionally, the device lets you know if your breath is deep enough by lighting a small LED.
Kitoki aims to promote calmness and prevent hyperventilation, which is why the cue is helpful. Little metal dots also measure your galvanic skin response during this breath, as well as after, to determine your stress level. Finally, Kitoki gives a little buzz when it thinks you are calm enough.
