I want to know how much it will cost me to hire a mobile app developer who can create a mobile pp that can work on both Android and iPhone. I want a premium quality mobile application for smartphone users, and I can expand my budget for that, but I want to know the Android and iPhone app development cost for planning the budget. It will be so helpful if anyone could kindly guide me how much budget I should set in order to get the best mobile app development services. Can someone help me out? I will be waiting for your responses.
