How to choose app developers in the UK
There’s a few things you should know:
Two major sections: the research you can do on your own, and the interview phase with the app developer, where you’ll explore their skills and expertise while they try to understand your business and your app. The research you can do at home is as follows:
- Review their portfolio: not only to see how many apps they’ve made and how successful they’ve been, but also to see which industries they’ve worked for. A niche social network app has vastly different characteristics and challenges to a mobile enterprise app for industry. Experience in your specific field of business is just as important as development skills.
- Recommendations: ask others in your industry who have launched successful apps to recommend a developer, or find out who made the most successful apps if there’s an industry benchmark.
- Check out our Market Place: You’ll find a wealth of information and app developer profiles in Business of App’s Marketplace.
