Mobile App Development

One codebase. Android & iOS. Both stores.

Full-cycle mobile app development for Android and iOS — built with React Native or Flutter from a single codebase, so you launch on both platforms without paying for two builds. Design, development, backend, and store submission handled end to end.

What's included

Everything you need,
nothing you don't.

Android & iOS Together

React Native or Flutter gives you both platforms from one codebase — one build to pay for, one codebase to maintain, native look and feel on each OS.

Native Performance

60fps animations, gesture-driven navigation, and platform-correct components. Where a feature needs to go native, we drop into Swift or Kotlin.

Both Store Launches

We handle the full submission gauntlet — App Store review guidelines, Play Store policies, listing copy, screenshots, and release management.

Push & Engagement

Push notifications, deep links, and in-app messaging wired in from day one — the retention loops that bring users back.

Offline-First & Sync

Apps that work on the subway. Local-first data with background sync, so a bad connection never means a broken experience.

Backend Included

Auth, database, file storage, and APIs on Supabase or Node.js — one team building the whole stack, no hand-offs between vendors.

How it works

Simple, transparent process.

01

Scope

We map the user flows, pick the platform strategy (cross-platform vs native), and fix the price. You know the cost before anything is built.

02

Design

Screen-by-screen UI design following Apple HIG and Material Design — you approve the clickable prototype before development starts.

03

Build

Weekly builds delivered to your phone via TestFlight and internal testing tracks. You watch the app come together in your hand, not in screenshots.

04

Launch

Store submissions for both Android and iOS, launch monitoring, crash triage, and a post-launch support window to smooth out the first release.

Pricing

Fixed-price.
No surprises.

Every project gets a written scope, fixed price, and start date before we begin. No hourly billing, no scope creep invoices.
