I've developed several apps with development firms in the past and have ALWAYS had God-awful experiences. To my surprise, Appstem was extremely successful in exceeding my unrealistically high expectations and they were able to give me what I wanted. Robert and the Appstem team were a pleasure to work with. If you're having second thoughts about working with the Appstem team, throw them out; they're the guys to go to.
