                                                                      Parental Dashboard

Interactive Gamification: 

Grush Apps are interactive games and apps that receive motion data from the Grush Brush and integrate it with a simulated image of teeth or any game theme. The games are designed to guide children to brush properly according to the American Dental Association’s child brushing recommendations. The child can battle monsters, fly spaceships, or ride a pony, all while being instructed in the ideal brush position and duration of brushing. 

Peace of Mind: 

The Grush Cloud stores statistical brushing data for parental tracking / monitoring. The Parental Dashboard App is used to track kids' brushing over time and reward them accordingly.

We have been working on Grush for 8 months and have already developed the Grush prototype hardware and alpha Grush Games.   We have proved that our motion sensing technology can detect brushing movements precisely. We have partnered with a world class mobile gaming studio, Threadbare Games to develop compelling Grush games to be available at launch.

Grush won the First Prize award at the TEEC Cup / North America Chinese Startup and Talent Summit out of 500 companies nationwide in Jan 2014 Grush presented to an audience of over 1000 people at the Santa Clara Convention Center. The judges were from major VCs in the US and China. The responses from the judges and audience were overwhelmingly enthusiastic.  This not only gave us good exposure to the investment community but also gave us a first hand market response for our product.

This technology was invented and is developed in the USA. A patent covering the technology has been filed in the US and internationally. 

Though the idea is innovative, the components are based on matured technology.   This means the technology risk is well controlled.  We have more than 30 years experience in managing complex manufacturing projects. While all projects entail risk, we have done everything possible to mitigate any potential risk to a very low level.
