How much does an app cost?: With more than 1.2 million mobile apps available in Google Play, the stretch of the functionalities of these apps can be imagined. The mobile apps can be broken into three major groups, namely simple apps, moderate (API/Database Apps), and complex apps. The process of developing these apps passes through six steps which are strategy formation, UI finalization, Design, development, QA, and Publishing. The cost of the app can be finalized after considering the size and features of the app.
