Frequently Asked

What in the world is Flutter?

Flutter is a cross-platform app development framework released by Google in 2017. Technically speaking, Flutter is a free, open-source mobile UI framework. Flutter is most easily explained by what it allows you to do - aka, create a native mobile app with a single codebase supporting both iOS and Android.

How long does it take to build an app?

It depends. Just like making a meal, app development time largely varies based on complexity. 3-6 months is the average for commercial scale apps we work on.

What does 'cross-platform' mean?

Cross-Platform means having a single codebase that can be deployed to Android and iOS devices - as opposed to having individual 'platform native' codebases for Android and iOS. Having a single codebase allows for more efficiency and a larger initial user-base!

How much should I expect to spend?

It depends! We offer a variety of services designed to align with various business stages and business goals. On average, your cross-platform app will cost between £40,000.00 and £250,000.00 to develop.

How do you support business goals?

Our passion at DevAngels is empowering businesses to reach their dreams - that's why we match our expert developers with brilliant business support to ensure you have everything you need to succeed! Apps are more than just apps to us - they're long term, strategic product development efforts.
