I work as a strategy consultant for a large internatinoal firm and would like to start my own app based business. I need an app that can be used on mobile phones. The most important functions include a user login, a fast and simple payment function and the possibility to take photos with the app. The idea is that users can pay small amounts through the app (1-2$) for a service that I provide to them (think of it as a kind of insurence agains certain events). If the anticipated event happens to a user, the user must be able to take a photo of a receipt and send it to me to process, therefore a simple background tool is neccessary in which I can see which user uploaded a photo and to have a look at the photo, as well as sending the user a massage in the app if the photo has been received (Ideally I can work with the photos that users ahve sent to me on a computer).
Further details can be discussed.
