You asked two developers to quote for your app. One says React Native, the other says Flutter, and each says his choice is the only sensible one. You are the one paying, but you can't tell who is right.
This guide explains React Native vs Flutter in plain words for a business owner. You will see what each one is, where the real cost of an app comes from, and which questions show you whether a developer knows what he is doing.
Quick answer
What are React Native and Flutter, in plain words?
React Native and Flutter are frameworks: ready-made toolkits that let a developer write one set of code and turn it into an Android app and an iPhone app. Without them, you would pay for two separate apps, built in two different languages, often by two different people.
Both are free and open source, which means anyone can use them without a licence fee. You pay for the developer's time, not for the tool.
React Native: built by Meta, written in JavaScript
React Native comes from Meta, the company behind Facebook. Its official site says Meta released it in 2015 and has maintained it since. Code is written in JavaScript, the same language used on most websites.
The app's buttons, text and lists are turned into the phone's own native parts. So a React Native app on an iPhone uses the same building blocks as other iPhone apps. Microsoft Office, Amazon Shopping, Shopify and Discord are listed on the official site as apps that use it.
Flutter: backed by Google, written in Dart
Flutter is an open-source framework supported by Google. Its code is written in a language called Dart. Flutter can build apps for phones, the web, desktop computers and some embedded devices from one codebase (one shared set of code).
Flutter draws its own buttons and screens instead of using the phone's built-in ones. So the app keeps the same design on Android and iPhone. Its official site lists Google Pay, BMW, Toyota, eBay and Alibaba among its users.
React Native vs Flutter: how do they compare for a business app?
For a normal business app, the two are close. The differences that matter to you are the language, how the screens are drawn, and which developers you can find to maintain the app later.
| Question | React Native | Flutter |
| Who backs it | Meta | |
| Language | JavaScript | Dart |
| One code for Android and iPhone | Yes | Yes |
| How screens are drawn | Uses the phone's own parts | Draws its own parts |
| Same look on both phones | Close, with small differences per phone | Same design on both |
| Website from the same code | Possible (React Native Web) | Possible (Flutter web) |
| Licence fee | None | None |
| Latest stable release (checked 1 Oct 2026) | 0.87, 11 August 2026 | 3.47.5, 18 September 2026 |
In the React Native vs Flutter debate, the last row matters more than it looks. Both tools had a new release within the last two months, so both are actively looked after. An app built on a tool that nobody updates becomes hard to fix when Apple or Google change their phones.
React Native vs Flutter: which one costs less to build?
Neither tool is cheaper by itself. Flutter app development cost and React Native app cost depend on the same things. These are the number of screens, what each screen does, and what the app must connect to.
A quote that changes a lot only because of the tool name is a warning sign.
What actually moves app development cost
These items make a quote go up or down, whichever tool is used.
Fixed costs you pay to Apple and Google
You pay the app stores directly, whatever tool your developer uses. As of October 2026, Apple's official enrolment page says the Apple Developer Program is US$99 per membership year. Google Play Console charges a one-time registration fee of US$25.

Flutter vs React Native: which is better for upkeep and hiring?
The better one is usually the one your developer has already shipped and maintained in real apps. An app is never finished at launch. You will need fixes, small changes and updates every year, so the tool must be one that someone can keep looking after.
Think about who will maintain it in three years
If your first developer leaves, you need another one who can read the code. Ask any new developer which of the two he knows, and how many live apps he has built in it. A clean, well-commented codebase in either tool is easier to hand over than a messy one in the "right" tool.
If you already have a website team
React Native uses JavaScript and React, which many web developers already use. If your website is built with React, your web team may find React Native easier to pick up than Dart. This is a reason to ask your current team first, not a rule.
When does each one make sense?
Both suit most business apps. These are the cases where one has a real edge.
React Native fits when
We built Kerbcop, a parking services app for a client in New Zealand, with React Native and Expo. Expo is a toolkit on top of React Native, and the official React Native site recommends it for new apps. It runs on iPhone, Android and the web from one codebase.
Flutter fits when
What should you ask a developer before choosing?
You don't need to judge the code. You need answers to a few plain questions, and the answers will tell you a lot.
- Which of the two have you used for live apps, and can I install one of them on my phone today?
- Why do you suggest this tool for my app, in one sentence that mentions my features, not the tool's fame?
- Will the source code be in a code account (such as GitHub) owned by my company from day one?
- Will the Apple and Google developer accounts be in my company's name, not yours?
- Who updates the app when Apple or Google release a new phone system, and what does that cost each year?
- Can I test both the Android and iPhone versions on my own phones before the final payment?
Ask for the store accounts in your company's name before work starts. Apple shows the account holder as the seller name on the App Store. For a company account, Apple asks for a D-U-N-S Number (a nine-digit business ID from Dun & Bradstreet), so ask for it early.
A short note before you decide
The Beyond Horizon has delivered 40+ projects, including the Kerbcop app in React Native. A good developer picks the tool after seeing your feature list, not before.
