We are in the need to hire the development of several apps, both for Android and IOS. The first one will be an app that will let our researchers to take a picture in the field where there is no internet connection, fill a form with certain information and store it up until they get to a place where they can upload the information collected. If possible, the app will get the geographic position and date automatically and insert it in the form. The information will be stored in a database, except for the pictures that will be named with the date + user + hour + min + jpg, which will be uploaded to a directory in our server. All the code sources have to be delivered to us for future improvements. We have to be able to modify easily the forms (for example, insert a new field).
