The short answer is … everywhere. Globally, indoors & out, on private property and in public spaces. In airports & on airplanes; in train stations & on trains. The basic idea is that if you can generate a photo with accurate location data (not just with GPS), then you have basic CleanApp capability.
The long answer is precisely why we are doing what we’re doing: there’s a need to harmonize reporting standards so that when folks send CleanApp reports, CleanApp responders will know exactly what they are looking for. This is largely a tech issue and we love working on this part of the problem. Our ideas here are really fun, in part because they rest on orchestrating many off-the-shelf tech pieces into a magnificent new composition. Please stay tuned.
