How to decide between an Android and an iOS app

For years the world of mobile apps has been dominated by two forces; Android and iOS. These mobile-giants have been providing users, developers and brands alike with new and exciting opportunities to get ahead and give themselves the advantage when it comes to the preferred platform.

Have you considered developing an app for both?

Our team sit down to discuss your business, users and goals before we recommend which platform is best for your app development project, whether it’s Android, iOS or a hybrid app, we’d never say both to tick all the boxes.

How long does it take to develop an iOS app?

We’ve developed iOS apps that have taken a few weeks and others that have taken up to six months, it comes down to the complexity of your idea and how difficult the technology is to implement.

How do we estimate the time it takes to develop iOS apps?

when it comes to iOS app development, we know the best ways to develop features, functionality and solutions in the most efficient way possible, always ensuring that we prioritise these elements based on the value they add to your users, brand and business goals.
