Frequently asked questions

What technology do you use?

Primarily Next.js, React, TypeScript, and Node.js. We deploy on Vercel and use PostgreSQL for databases. Modern, battle-tested tools that scale.

Can you build a mobile app?

We specialise in web applications, but modern web apps work great on mobile. If you specifically need a native iOS/Android app, we can advise on the best approach.

How much does an app cost?

It depends entirely on scope. A simple MVP might start from £5,000, while a full-featured SaaS product could be £15,000+. We'll scope it properly before quoting.

How long does development take?

An MVP typically takes 4–8 weeks. More complex applications can take 3–6 months. We'll break it into milestones so you see progress throughout.

Do you offer ongoing support?

Yes. Most of our app clients work with us on a retainer basis for continued development, bug fixes, and new features. Software is never truly finished.

Can you work with my existing codebase?

Absolutely. We can audit your existing code, fix issues, add features, or help you migrate to a better stack. We're not precious about starting from scratch.
