Or rather, your business needs an app to stay competitive, but apps are complex and expensive to create and require constant support for years.
You could put together an in-house team to build and maintain your app, but the average developer salary in the UK is £56,700. And that's for one developer, not a team. And do you really want to transition into a software development company? Is that what your customers want?
We'll develop and maintain your app for Android and iPhone from just £499/mo. It's a no-brainer.
As hard as they might try, I think it unlikely that my son or dog will actually be able to write any code. But they're in the team for moral support, not their development chops.
