Conclusion
The UK market for mobile app development is made up of companies that handle everything from the first idea through to keeping an app running afterwards. Some put more weight on the design side, others on the building and the later updates.
It all depends on the specific needs of a project. A one-off piece of work can go one way, while something that needs to last and change over time might need a different kind of setup. The shared part is that they all focus on creating the apps and the pieces around them that make the whole thing hold together.
