We are asked this in almost every mobile discovery call, and our honest answer disappoints people who want a winner: we ship production apps with both Flutter and React Native, and both are good. What matters is which one fits the product, the team that will own it, and the rest of your stack. This is the checklist we actually use.
First, what both get right
Both frameworks let us build one codebase that ships to the Play Store and the App Store. Both have mature tooling, hot reload, good testing stories and large communities. For the typical business app — lists, forms, maps, payments, notifications, an account area — either will produce an app your customers can't tell apart from a native one.
So we don't start from features. We start from four questions.
Question 1: Is there a web product, and what is it written in?
If your web app or admin is built in React and TypeScript — as most of our web products are — React Native usually wins. Your developers can move between web and mobile, you can share validation logic, API clients and types, and hiring one kind of engineer is easier than two.
If there's no web product, or the web side is a simple marketing site, that advantage disappears and the other questions decide.
Question 2: Who will own the app after launch?
We build for handover. If your in-house team is JavaScript-first, we lean React Native. If you're hiring fresh, or your team already knows Dart, Flutter is a perfectly good bet. The worst outcome is an app nobody on your team can confidently change.
The best framework is the one your team can still change confidently a year after we've handed it over.
Question 3: How custom is the interface?
Flutter draws every pixel itself. That makes highly custom, animated, brand-heavy interfaces — games, playful consumer apps, apps that must look identical on every device — a pleasure to build. Our casual games lean this way.
React Native uses the platform's native components. That's an advantage when you want an app that feels at home on each platform with little effort, and a small cost when you want a pixel-identical custom look everywhere.
Question 4: What parts of the phone do you need?
Cameras, Bluetooth devices, background location, payments SDKs, barcode scanners — check the specific SDKs you need before choosing. Both ecosystems cover the common ones well. For niche hardware or a vendor SDK that only ships native code, we check which framework has a maintained binding, and budget time to write one if neither does.
How it plays out
| If your situation is… | We usually pick |
|---|---|
| React/Next.js web app, JS team | React Native |
| No web product, custom animated UI | Flutter |
| Game or playful consumer app | Flutter |
| Business app that should feel native per platform | React Native |
| Heavy use of a vendor SDK | Whichever has a maintained binding |
Performance: the question behind the question
People often ask “which one is faster?” when they mean “will my app feel slow?”. In our experience, apps feel slow because of what the app does, not the framework:
- Loading too much data on start-up instead of paging it.
- Large, unoptimised images in long lists.
- Network calls on the main path with no cached state to show first.
- Testing only on flagship phones.
We test on a mid-range Android phone throughout the build, because that is the phone most Indian users actually carry. Fix those four things and either framework feels fast.
What we avoid
- Choosing on hype. Framework popularity shifts; your app has to live for years.
- Mixing both in one product. Two mobile stacks double your maintenance for little gain.
- Skipping native knowledge. Every cross-platform app eventually needs someone who understands Xcode signing, Android permissions and store review. We keep that knowledge in the team.
The short version
If you already have a React web product, or a JavaScript team who will own the app, we'll probably recommend React Native. If the interface is highly custom or playful, or there's no web codebase to share with, Flutter is often the better fit. Either way, we'll explain the choice in writing during scoping — and you'll get an app on both stores from one codebase.
