One Peak for React Native development.

We build iOS and Android apps from a single codebase — fast shipping, native feel, and real architecture that survives iteration.

Why React Native?

One codebase, two platforms, without giving up the native experience users expect.

  • Single codebase — up to 95% shared code across iOS and Android, one build cycle, lower cost
  • Native performance — renders real native components, not webviews
  • Faster to market — skip the overhead of two separate native teams
  • Mature ecosystem — backed by Meta; libraries for navigation, auth, payments, analytics

Why One Peak?

We've shipped real mobile products under real constraints.

  • Trainerrr (MCP + OAuth mobile app) and Eazmenu (realtime QR ordering) are in production
  • Strategy before code — we scope the mobile experience around the core workflow first
  • Full stack in one team — backend, API, and mobile handled by the same people

Our React Native services

We build cross-platform mobile apps that behave like native.

  • iOS & Android app development — full build from UX to store submission, CI/CD, analytics
  • MVP mobile build — 2 core features, auth baseline, cloud backend, 30-day support
  • API & backend integration — Supabase, REST, third-party services, realtime sync
  • App store submission & launch — store assets, privacy policy, review preparation
  • Post-launch iteration — behavior report, prioritized backlog, next sprint plan

Our process

From first conversation to launch.

01

Discovery & Scope

We clarify the buyer, the core workflow, and platform requirements before any design or code begins.

Deliverables
Scope doc, feature priority list, architecture direction
Process
1 workshop session, async Q&A, written summary
02

Design

High-fidelity screens and flows for the core journey, optimised for the way people actually use the product.

Deliverables
Figma prototype, component system, handoff-ready specs
Process
2 feedback rounds, async or live review
03

Build

Implementation with clean architecture, tested as we go and wired to a real backend and staging environment.

Deliverables
Working product, documented codebase, staging environment
Process
Weekly milestone demos, async updates
04

Launch & Iterate

We deploy, set up analytics, review the first real usage, and plan the next cycle with you.

Deliverables
Live product, analytics dashboard, iteration roadmap
Process
30-day post-launch support window

Technical expertise

What we bring to the build.

Clean architecture / separation of concerns

Business logic isolated from UI — testable and scalable as the product grows.

Supabase & REST APIs

Auth, database, realtime, and storage — full backend integration.

Automated testing

Jest unit tests plus Detox end-to-end coverage for critical flows.

Optimised UI/UX

React Navigation, gesture handling, and smooth transitions across devices.

CI/CD & store delivery

Automated build and release pipelines via EAS Build or GitHub Actions.

Practical answers

Questions founders ask before moving forward.

Why React Native instead of native Swift/Kotlin?

A shared codebase cuts cost and timeline meaningfully without sacrificing the native feel users expect. For most startup products, it's the right default.

How long does a mobile MVP take?

Roughly 8–14 weeks for a focused 2-feature MVP, depending on backend complexity and design scope.

Do you handle both iOS and Android?

Yes. One codebase, tested on real devices for both platforms, and submitted to both stores.

Can you integrate with our existing backend?

Yes. We connect to any REST or GraphQL API. If you don't have a backend yet, we build one with Supabase or Node.js.

What happens after launch?

30 days of post-launch iteration support is included. After that we offer sprint-based cycles or a retainer.
