I would like to get a social sharing mobile app developed. It needs to be similar to something like instagram with a few variations. Including the ability to share posts to facebook instagram and wordpress blogs. I would like the app developed for Ipad Iphone and Android. The user should be able to tag pictures like in facebook gallery but only with select tag descriptions to be stored and updated in a database. please could you give and estimate of the development time required to get a working prototype ready and the cost involved.
