Not something I've ever played with before but basically I'm looking to make a mobile app which is set around a database. It's nothing fancy I just have no idea where to start and googling has just made it seem way more complicated. Basically I want to have a database of postcodes linked to relevant delivery charges, then on the app side of it you just enter the postcode and it returns the delivery charge. Anyone got any ideas or suggestions?? Needs to be done at no cost too but a lot of these 'app builders' have charges in there somewhere
