iOS, Android
And Web Apps
Built Right
We build iOS and Android apps with React Native and Expo, and full-stack websites with Next.js and React. We also specialise in test automation with Playwright, Cypress and Selenium, so what we ship is tested before your users ever see it.
- React Native & Expo
- Next.js & React
- Playwright, Cypress & Selenium
- App Store & Play Releases
What we build and test
Web, mobile, and specialised QA
Three clear offers: full-stack Next.js and React products, React Native and Expo apps for iOS and Android, and test automation with Playwright, Cypress or Selenium.
Web apps
Next.js and React websites
Full websites and products built with Next.js, React, Node and TypeScript. Fixed projects typically start from about £9,000 (~$11,700), depending on complexity.
Mobile apps
React Native, iOS and Android
Production apps with React Native and Expo for both stores. Fixed projects typically start from about £14,000 (~$18,200), depending on complexity.
Test automation
Playwright, Cypress and Selenium
We specialise in automated testing for web apps: Playwright, Cypress or Selenium suites with CI gates. Fixed automation projects typically start from about £4,950 (~$6,450).

Sound familiar?
The delivery problems that cost you most
These are the problems we are brought in to fix.
Two codebases, two teams, double the cost
Separate iOS and Android builds mean every feature gets written, tested and shipped twice.
An app that has been six weeks away for six months
Estimates slip because the architecture was never agreed before the code started.
A prototype that can't become a product
No types, no tests, no migrations. What proved the idea now blocks the roadmap.
A codebase nobody wants to touch
Inherited work with no documentation, so every small change carries an unknown risk.
Releases that break things quietly
Without CI, tests and monitoring, you find out from your users rather than your dashboard.
Agencies that hand over and disappear
You end up owning software your own team was never equipped to maintain.

Our Process
How We Work
A four-step process that takes a product from an idea to a released app, without the surprises.
Discovery
We learn your product, users and constraints, then agree the architecture, the stack and a delivery plan with honest estimates.
Foundations
Typed data model, design system, authentication and CI on day one, so every change after that is fast and safe to ship.
Build in Sprints
Features land behind pull requests with automated tests. You get a working build every sprint, on a device or a preview URL.
Release & Support
We handle App Store, Google Play and Vercel releases, wire up monitoring, then hand over documented code your team owns.
Why RedQA
An engineering team that works like your own
We don't hand over a zip file and disappear. We're in your Slack, aligned to your sprint, and building software your team can still maintain a year from now.
- React Native and Expo apps from one TypeScript codebase
- Next.js and React websites, typed end to end
- Playwright, Cypress or Selenium automation in CI
- A named senior engineer building your product, not a junior
- App Store, Google Play and Vercel releases handled for you
- Code you own, documented and handed over properly
Client Feedback
What Our Clients Say
“We needed someone who could step in fast and give us structure. They built a test plan from scratch, set up the automation framework, and surfaced a defect that would have caused serious data loss in production. First-rate work.”
Operations team
B2B software company · Clearer Group
“Our news APIs need to perform flawlessly under load when stories break across global channels. The API testing coverage they put in place gave us the confidence we needed before every major release.”
Engineering team
Global media organisation · BBC
“Testing an AI chat system is a different challenge, you need to verify accuracy against source material, not just check that the UI works. They understood that immediately. The accuracy audit was thorough and the UX findings were spot on.”
