Because of the nature of the app development process, the top Android and iOS app developers can be found scattered across the globe, from California in the USA to Europe and South East Asia. In many cases, these companies split their office between multiple locations. For instance, they may open headquarters with sales and marketing, let's say in the US and its design and development arm somewhere in India or Eastern Europe. On the other hand, there are strong agencies that are wholly located in India and Latin America too, and the UK always has a good proportion of the top app developers.
