I have always wondered about the kind of electromagnetic waves we are exposed to on a regular basis, and more specifically cell phone waves. I want to make an app that keeps track of the signal strengths of the carrier, WiFi activity etc over time and map them in a meaningful way. I am in the process of researching how to accurately quantify the exposure. I want to be able to present the data in an easily comprehendible way - " Your exposure is equivalent to _ seconds in the microwave oven". The above is a basic wireframe of what it might look like on a phone.
