How to Hire a React Native App Developer

You've got an app idea and a budget that doesn't stretch to two separate teams for iOS and Android. So you've heard React Native is the answer — and it often is. But "hire a React Native developer" hides a lot of variation, and the wrong choice on a mobile app is painful to undo.

I build cross-platform apps with React Native, so here's how I'd vet one if I were on your side of the table.

The short version: for most apps, one good React Native developer gets you both iOS and Android from a single codebase — but only if they understand the native edges, app-store realities, and how to ship updates, not just write screens.

Why React Native (and when it's the wrong call)

React Native lets you build iOS and Android from one codebase, which usually means roughly half the cost and time of two native teams. It's an excellent fit for content apps, marketplaces, dashboards, loyalty and ordering apps, and most SaaS companions. Where I'd think twice: heavy 3D/AR, intensive real-time graphics, or apps whose entire value is a platform-specific feature. For 80% of products, it's the pragmatic choice.

What to actually check in a React Native developer

• Real apps shipped to the App Store and Google Play — not just demos
• Comfort dropping into native modules when JavaScript isn't enough
• Knowledge of the boring-but-critical parts: builds, signing, store submission, OTA updates
• State, offline handling, and performance on mid-range phones (not just the latest iPhone)
• Familiarity with Expo vs bare workflow, and an opinion on which fits your project

That app-store experience matters more than people expect. Plenty of developers can build screens; far fewer have actually navigated Apple review, provisioning profiles, and a botched release at 11pm.

How to review their work

Download one of their published apps and use it. Is it smooth? Do transitions stutter? Does it handle a flaky connection gracefully? Then ask them to walk you through a hard problem they solved — a strong React Native developer will have war stories about a native quirk or a store rejection, told plainly.

Cost and timeline

Freelance React Native rates land roughly €350–700/day depending on seniority. A focused MVP app is often 4–10 weeks; a polished, feature-rich app, several months. Cross-platform saves money versus two native builds, but don't expect "an app" for a few hundred euros — that price buys a template, not a product.

Build your app with me

This is squarely what I do — React Native apps taken from idea to the stores, plus the web/backend they connect to. Have a look at my projects for real examples, and if you're ready to build, let's talk.
