About our client

Our Client’s device is a smart diffuser unit that diffuses essential oils directly from the glass bottle directly into your room for absolute potency and purity. It accommodates up to 4 oils and is able to diffuse the oil without adding water to the product. The device works by using high volume low pressure air to spray out oil without heating, mixing or using ultrasonic diffusion but using the venturi effect to atomize the oil. 

We are developing the APP for both IOS and Android. It will control the unit, as well as refill purchasing features.
