Top iOS App Development Agencies 2016


If you want to build a successful iOS app and business, then working with an app development agency could help you stay competitive in today’s crowded marketplace. While DIY app development is great for some, working with an agency means you’ll get access to experts in iOS app development, branding and mobile strategy.

App development agencies provide specific expertise. They’ve learnt from experience and have a deep knowledge about what works and what doesn’t. Developers, employed by agencies, will likely be up-to-date with the latest trends and technology and continually upgrading their skills. This means they’ll understand new programming languages such as Apple’s Swift (which hit the coding world in 2015) and how apps can meet high security standards. With the public becoming increasingly aware of digital security threats, the pressure is on app developers to prioritise security.

While some agencies focus on design and development, others take a wider view and offer mobile app strategy, branding and optimisation. Whether you’re looking for an agency to develop a strong brand for your new app business, or want to outsource your app development on a budget, you’ll find something to suit your needs in our roundup of the top iOS app development agencies.

The agencies are:
