smartphoneSolutions — 02 / Mobile Apps

One codebase,
two app stores.

We build iOS and Android apps with React Native and Expo — native-quality performance, full access to device capabilities, and a single codebase that keeps both platforms in lockstep. From rapid MVPs to production apps with 10k+ users, the same standard applies.

How we work — Step by Step

The process,
without the mystery.

01

Product Scoping

We map core user flows, identify the smallest version of the app worth shipping, and agree on what stays out of v1. Scope is protected from day one.

02

UX & Wireframes

Low-fidelity screens first, high-fidelity mockups second. You approve every flow before a line of code is written so surprises don't appear at sprint 3.

03

React Native Build

Expo SDK, TypeScript, and clean architecture. We use battle-tested libraries — not bleeding-edge experiments — so your app still runs in two years.

04

Backend & Auth

Supabase, Firebase, or a custom API — whichever fits your stack. Auth, push notifications, analytics, and crash reporting wired in from day one.

05

TestFlight & Play Console

We handle Apple and Google developer accounts, app icons, screenshots, store copy, and the review submission. You get a real device build to hold.

06

Launch & Iteration

Over-the-air updates with Expo mean we can ship fixes in minutes — no waiting for App Store review. Post-launch support included.

Investment
Scoped to your project.

Every project is different — so every quote is custom. After a short discovery call, you receive a fixed scope and a clear proposal in writing. No retainers, no surprise invoices, no billable-hour games.
