Mobile Apps with React Native: How to Reach iOS and Android with a Single Codebase

The Dilemma: iOS, Android, or Both Platforms

If you're a small business owner or entrepreneur with a mobile app idea, you've probably faced this question: should I develop for iOS, Android, or both? The traditional answer was expensive: hire two development teams, double your costs, double your timeline, maintain two separate codebases simultaneously. Many entrepreneurs ended up choosing just one platform and leaving money on the table.

At imSoft, we know entrepreneurs don't have unlimited budgets. That's why for years we've worked with technologies that let you reach both platforms without breaking the bank: React Native does exactly that.

What is React Native and Why Does It Work?

React Native is a framework developed by Meta (formerly Facebook) that lets you write code once and run it on both iOS and Android. Unlike a web app embedded in a container (which is slow and limited in device access), React Native generates actual native code for each platform.

What this means in practical terms:

• One development team, not two. You save 40-50% on development costs.
• Centralized maintenance. One fix is implemented once and reaches both platforms.
• Full access to phone hardware: camera, GPS, sensors, push notifications, everything without limitations.
• Performance similar to a native app. Users won't notice the difference.

At imSoft, we've delivered over 15 mobile applications with React Native to retail, logistics, and fintech companies across Mexico and Latin America. The result is always the same: fast, maintainable apps with realistic budgets.

When React Native Is Your Best Option

Not all applications fit React Native (though most do). Here are the cases where it definitely works:

• CRUD applications: apps that query databases, allow creating, reading, updating, and deleting information. This includes most enterprise applications for small businesses.
• Marketplaces and e-commerce: mobile stores, service apps, booking platforms. React Native is designed exactly for this.
• Social and messaging apps: React Native's performance handles hundreds of simultaneous users without breaking a sweat.
• Internal management tools: if you need an app for your team to manage tasks, inventory, routes, etc.

The cases where pure native code (Kotlin for Android, Swift for iOS) is justified are very specific: games with complex 3D graphics, medical applications with specialized sensors, or demanding HD video streaming. For 90% of Mexican small businesses, React Native is the right solution.

The Real Savings: Concrete Numbers

Let us put it in numbers. A typical mobile application developed in pure native code (separate iOS and Android) costs between $80,000 and $150,000 USD and takes 4 to 6 months.

The same application in React Native costs between $40,000 and $70,000 USD and is delivered in 2 to 3 months. We're not cutting quality; we're eliminating duplicate effort.

But there's more: monthly maintenance costs are cut in half. A bug that would need to be fixed in two codebases is now fixed once.

For an entrepreneur launching their MVP (minimum viable product), this means being able to invest more in marketing, add more features, or simply maintain your startup's financial health.

What You Need to Know Before Getting Started

React Native isn't a magic wand. It requires a team with real experience in the framework. We've seen startups hire "full stack" developers without React Native experience and end up with a slow, buggy project.

At imSoft, what we do is simple: we evaluate your idea, identify whether React Native is the right tool (sometimes the answer is no, and we'll tell you), and if it is, we build your app to professional quality standards.

Our team masters React Native from data architecture to performance optimization. We've learned to avoid common pitfalls, and that translates into clean, maintainable, and scalable code.

The bottom line is simple: if you want to reach iOS and Android users without spending double, React Native is your answer. It's not the only option, but for most cases, it's the smartest.
