Looking for an experienced mobile app developer that can provide a simple map application and get the app on Google and Apple app stores. (We are open to the idea of creating a single web based application if it makes more sense to do it that way).
The map should be based using Google maps and feature a tiled historical image overlay for a specific area. It should feature a "Transparency Toggle Tool" to compare a 1990 image to a recent Google maps image. Our app users will use the image to reference their location in real time. We provide the georeferenced image and it is expected the developer knows how to turn it into a mobile app. A simple authentication (login) framework is needed so that users must login the first time they use the app.
To be considered, applicant must provide past examples of creating a mapping application.
