Frequently Asked Questions

What is the difference between native and cross-platform app development?

Native app development involves programming separate apps for each operating system (e.g. iOS, Android). Cross-platform mobile app development, by contrast, typically involves creating a single web app and automatically wrapping it in a native wrapper that enables it to be submitted to multiple platforms (including iOS and Android) after only needing to develop it once. This approach is also commonly known as ‘hybrid app development’.

What are the advantages of each type of app development?

Native app development delivers the greatest levels of performance and integration with the underlying devices, but also incurs the highest level of costs. If you are only targeting a single platform (e.g. iOS) or are producing a performance/animation intensive app (e.g. a mobile game), then natives is the way to go.

Cross-platform or hybrid app development enables the use of widely available web development skillsets to produce its applications. This allows for very fast development times as the app is only developed once, but deployed to multiple platforms; however, it does have reduced levels of performance on devices.

Another approach to delivering mobile solutions is responsive design, that detects what device is being used and adjusts accordingly. A key benefit of this approach is the flexibility to target a much wider range of devices, however you may miss out on device-specific functionality.
