App Making Company — UK

An app making company
that gets it right first time.

You have an idea for an app. You need someone to make it real. Wall & Fifth is an app making company that builds web apps and mobile apps at a fixed price from £16,000 — properly built, live in 8 weeks.

The problem with most app making companies

Finding a company to make your app should not be this hard.

Overpriced agencies

£80k quotes, 6-month timelines, and teams full of people who never touch your code. You end up paying for project management, not app making.

Cheap freelancers

The price looks right until the app breaks under real users. Messy code that no decent developer will maintain. You end up paying twice.

No-code platforms

Quick to start, impossible to grow. The moment your app needs custom logic or real integrations, you have hit the ceiling and need to start again.

Wall & Fifth is an app making company that does it properly: fixed price, real code, direct access to the person making your app.

What this app making company builds

Web apps. Mobile apps.
Made properly from day one.

Every app we make is production-grade code on modern foundations. Not a prototype, not a mockup — a real, working app ready for real users.

Web apps

Dashboards, portals, booking systems, admin panels, internal tools, member areas. Built in Next.js, React, TypeScript, and PostgreSQL. Works on every device, no app store required.

Mobile apps

Native iOS and Android apps from a single React Native codebase. Push notifications, camera, GPS, offline support. We handle App Store and Google Play submission.

App infrastructure

Authentication, database architecture, API layer, CI/CD pipelines, SSL, monitoring, and global CDN. Every app is production-ready from the moment it launches.

Payments & integrations

Stripe billing, email notifications, third-party APIs, webhooks. If your app needs to connect to an external service or process payments, we build it in from the start.
