Tracking\CheckIn App

This is for both Android and iOS apps.

I am looking to get a tracking app built. It is a simple app where people check into a place (like you would on Facebook) - Their location would be shown on a map and a list of places shown that they can choose to check into. Reverse geo-coding from the phone's GPS. This data would then be sent to a database.

There would then be a second app for each place\location. This would show who is currently checked into a place.

There will then a web page where people can sign to register their place location and thus get access to the second app. There will be a subscription based billing process in the sign up process for the place. No billing in the user checkin app.

I am currently working on the page mock ups and functional flow.
