Tzoa is the world’s first enviro-tracker that measures air quality and UV using the latest in sensor technology. Simply put, we connect you with your environment. By using Tzoa you will be creating a crowdsourced map of environmental data in real-time, which you can access with a smartphone app. With Tzoa you can choose the least polluted bicycle routes; improve your indoor air quality; and know when you’ve been in the sun too long, or not enough.
