App studio · London & Manchester
YOUR IDEA.
OUR CODE.
SHIPPED.
We're a UK app studio with 100+ apps shipped worldwide. Start to finish — design, build, launch and support. Bring your idea, or let us create something special for you.
✦ Who we are
A senior UK app studio
that ships, not pitches.
RAZZA is a small, senior team of product designers and native mobile engineers based in London and Manchester. Over the past decade we've shipped more than one hundred apps for founders, agencies and enterprise clients across the United Kingdom, Europe, the Middle East, the United States and Asia. We work in the App Store, on Google Play, on the web and increasingly on connected TV — one focused studio, one shared quality bar, no outsourcing.
Most of our clients come to us after a bad experience with a freelancer marketplace or a body-shop agency. They arrive with a half-built codebase, a rejected App Store submission or a designer's PDF that never became a working product. We're used to picking work up mid-flight, diagnosing what's really going on and getting a real, testable build into their hands quickly — usually within two weeks of the first call.
Why teams pick RAZZA
Small studio. Serious craft.
No juniors on your project.
— Native by default
Swift, Kotlin, real performance
We build in Swift and Kotlin for iOS and Android, with React Native reserved for cases where genuine code sharing pays off. Your app should feel like it belongs on the device — smooth scrolling, correct haptics, proper accessibility.
— Design owned in-house
Interfaces people keep on their home screen
Every project ships with a considered visual system, motion language and empty states. We design in Figma, prototype in code and iterate against real device screens — not marketing mockups.
— Support after launch
Retainers, updates, on-call fixes
Launch day is the start, not the finish. We stay on for OS updates, App Store review responses, crash triage and roadmap iteration — with clear monthly reporting so you always know what changed.
Our studio handles the full product lifecycle: discovery workshops, technical architecture, native mobile builds, backend and API work on Supabase and Cloudflare, Stripe payments, streaming and Chromecast integrations, on-device AI features, App Store and Google Play submissions, and long-term maintenance retainers.
We're comfortable in complicated categories — live sports data, IPTV, fintech onboarding, health tracking, public-sector accessibility — and we're just as happy shipping a small, elegant consumer utility. If the brief is real and the ambition is honest, we're interested.
