Frequently asked questions

Do you build native or cross-platform mobile apps?

We usually recommend cross-platform (for example React Native) for cost and speed, and discuss native development when your app needs it.

What is an MVP?

A Minimum Viable Product: the smallest version that delivers real value, so you can launch, learn and improve before investing in everything.

Can you take over an existing app?

Often, yes. We start with a code and architecture review and tell you honestly whether to improve it or rebuild parts of it.

Have an app idea or a process to digitise?
