Bitvero

Web and mobile,
built properly.

Applications that perform, scale and users actually want to use. iOS, Android and web — from one team, one codebase, one fixed scope.

Sam is live — web & mobile app development

Whatever it runs on — we build it.

Customer-facing products, internal tools, mobile apps — designed, built and deployed end to end. No hand-offs, no gaps.

React + Next.js

Web Applications

Complex, data-driven web apps — customer portals, booking systems, dashboards, marketplaces. Built for real users, not demos.

React Native

Mobile Apps

iOS and Android from a single codebase. Native performance, native feel. Ship fast without maintaining two separate teams.

Custom built

Internal Tools

Dashboards, admin panels and ops tools your team actually uses. Built around your specific workflows — not squeezed into off-the-shelf software.

RESTful + Webhooks

API & Integrations

Connect your app to anything — payment providers, CRMs, ERPs, government APIs. Clean, documented, versioned.

PWA

Progressive Web Apps

Web apps that install like native apps — offline-capable, fast, and available on any device without an App Store submission.

Migration

Legacy Modernisation

Moving old systems to modern stacks without breaking what already works. We've rescued codebases others gave up on.

Why React Native — and why it matters.

We back React Native because we've shipped a live mobile app with it. This isn't a preference — it's a conviction.

React Native
Native iOS/Android
Web Only
Single codebase for iOS & Android
Native look, feel and performance
Access to device hardware (camera, GPS, push)
App Store + Play Store ready
Shared logic with web frontend
Half the development cost
Over-the-air updates (Expo EAS)

App projects fail for the same reasons.
We prevent them.

Separate iOS and Android teams from day one

React Native — one codebase, both platforms, half the cost

No-code app builders that can't scale

Custom code you own — no platform risk, no lock-in

Skipping UI approval before build starts

Figma designs approved before a single component is written

App delivered with no handover docs

Full code handover, docs, and ongoing support if you want it

Structured. Transparent. Accountable.

Fixed scope, no black-box development, and a clear outcome at every stage.

01
Fixed scope, no surprises

Scope & Spec

We map every user journey, define the data model, and agree a spec in writing before any code is written.

02
Approved before build

UI Design

Figma wireframes to high-fidelity UI. You sign off exactly what we're building — screens, flows, edge cases.

03
Staging URL, every 2 weeks

Build

Sprint-based development. GitHub access, staging environment, Slack update every Friday. You see it grow.

04
100% code ownership

Launch & Handover

App Store submission, production deploy, monitoring and full documentation. You own everything — we're never a dependency.

Modern. Proven. Maintainable.

We build our own products.

We don't just build for clients. Bitvero runs its own apps — which means we know the full lifecycle: discovery, build, App Store submission, post-launch scale.

Let's scope it properly.

Sam is Bitvero's development specialist. He'll give you an honest view of what your app needs, what platform to build for first, and what it realistically costs.

  • Should I build a mobile app or a web app first
  • How much does a React Native app realistically cost
  • What's the App Store submission process like
  • Can you take over an existing codebase
