App Development Studio · London, UK

We build apps people actually keep.

Bizleads is a product-focused engineering studio. We take ideas from first sketch to the App Store and Google Play — designing, building and scaling iOS, Android and web applications that ship on time and hold up under real load.

What we do

Full-stack product engineering, under one roof.

All services
01

iOS Development

Native Swift & SwiftUI apps engineered for iPhone, iPad and Apple Watch — built to Apple's Human Interface Guidelines and App Store review standards.

SwiftSwiftUIApp Store
02

Android Development

Kotlin and Jetpack Compose applications optimised for the full range of Android devices, with clean Material design and Play Store-ready release pipelines.

KotlinComposePlay Store
03

Cross-Platform

One codebase, every store. We use React Native and Flutter to ship faster when it makes sense — without sacrificing the polish users expect from a native app.

React NativeFlutter
04

Product & UX Design

Research, prototyping and interface design that turns a rough idea into a clear, testable product. We design in the open and validate with real users before a line of code is written.

FigmaPrototypingDesign systems
05

Backend & APIs

Secure, observable backends and APIs that scale with your user base — cloud infrastructure, real-time data, payments and authentication, built for production from day one.

Strategy & Growth

From MVP scoping to App Store optimisation, analytics and retention. We help you launch the right thing — then improve it with data once it's live.

Engineering you can trust

Production-grade from the very first commit.

We don't build throwaway prototypes that fall over the moment real users arrive. Every Bizleads project ships with automated testing, CI/CD, monitoring and clean, documented code your team can own.

  • Automated test suites and continuous integration on day one
  • Crash reporting, analytics and performance monitoring built in
  • Clear handover docs — no lock-in, the code is always yours
CheckoutView.swift 
struct CheckoutView: View {
  @StateObject var cart = Cart()

  var body: some View {
    VStack(spacing: 16) {
      OrderSummary(items: cart.items)
      PayButton(total: cart.total) {
        await checkout.submit()
      }
    }
    // shipped to 9.4M users
  }
}
How we work

A clear path from idea to launch.

No mystery, no surprises. You'll always know exactly where your product is and what happens next.

01 / DISCOVER

Discovery & scoping

We pin down the problem, the users and the business goals — then turn that into a realistic roadmap, fixed scope and a transparent quote.

WorkshopsUser researchRoadmap
02 / DESIGN

Design & prototype

Wireframes become interactive prototypes you can tap through. We validate the experience before committing engineering time.

FigmaPrototypesDesign system
03 / BUILD

Build in sprints

Two-week sprints with working software at the end of each one. You see real progress and can steer the product the whole way through.

AgileWeekly demosCI/CD
04 / LAUNCH

Launch & scale

We handle App Store and Play submission, then keep the app healthy with monitoring, updates and growth work after release.
