Cross-Platform App Development in Florida

One app, one codebase, live on both iPhone and Android.

One Codebase for iPhone and Android

A cross-platform app is written once and runs on both iPhone and Android. Instead of paying for two separate apps, you pay for one codebase that ships to both stores. For most business apps and startup launches, that means a faster launch, a smaller budget, and one set of features to keep up to date.

Mobile App Development Company Florida builds cross-platform apps in Flutter and React Native, the two most popular tools for the job. We're powered by The App Bros, a Fort Lauderdale studio that has been building apps for more than a decade. Our team designs your app, builds it once, tests it on both platforms and launches it on the App Store and Google Play.

Cross-platform apps usually save you a big share of the time and money of building two native apps, and you reach both audiences on day one.

Flutter vs. React Native: Which Fits Your App?

Both are proven. Both power apps with millions of users. The better choice depends on your app and your plans.

Flutter is made by Google and uses the Dart language. It paints its own screens instead of using each phone's built-in controls, so your app looks the same everywhere and animations run smoothly. It's a strong pick for apps with a custom, branded look.

React Native is made by Meta and uses JavaScript or TypeScript. It uses each phone's own controls, so apps pick up the native look of each platform. It's a strong pick if you already have a web app built in React, or a team that knows JavaScript.

We build in both, so we have no reason to push one. We'll recommend the one that fits your app.

Cross-Platform vs. Native: The Trade-Offs

Cross-platform isn't right for every app. Here's the honest version:

  • Cost and speed: cross-platform wins. One codebase means less to build, test and update.
  • Performance: for most business apps, users can't tell the difference. For heavy games, video editing or heavy animation, native still has the edge.
  • Device features: most phone features work fine through plugins. Brand-new Apple or Google features can take time to reach Flutter and React Native.
  • Long-term updates: one codebase is cheaper to maintain, and new features ship to both platforms at once.

If your app depends on brand-new device features or top-end performance, we'll point you to native. Native iOS & Android development

Adding a Web App or Admin Dashboard

Many apps need more than a phone app. Your team may need a dashboard to manage users, orders or content. Your customers may want a web version. Flutter can also build for the web, and React Native pairs naturally with React web apps, so we can often reuse design and logic across all three.

What a Cross-Platform App Costs

Here are the starting ranges from App Cost Finder, our free app budget tool:

Budget tierStarting rangeBest for
Lean MVP$15k – $30kA focused first version with core features
Growth build$20k – $50kMore polish, dashboards, payments, messaging and integrations

Starting ranges, not final quotes. Cross-platform is often the most budget-friendly way to launch on both iPhone and Android.

Cross-Platform App FAQs

Is cross-platform cheaper than native?

Usually, yes. You build one app instead of two, so design, development and testing cost less. Updates cost less too, because one update ships to both platforms.

Will a cross-platform app feel native?

For most apps, yes. Flutter and React Native apps can be fast and smooth, and most users can't tell them apart from native apps. Very heavy apps, like games or video editors, may still run better native.

Should I choose Flutter or React Native?

Choose Flutter for a custom, branded design that looks identical everywhere. Choose React Native if you already use React on the web or have a JavaScript team. We build in both and will recommend one at your free consultation.

Can you convert my existing app to cross-platform?

Often, yes. We review your current app, its code and its features, then tell you whether a rebuild in Flutter or React Native makes sense, and what it would cost.
