Cross-Platform App
Development Services

Stateside Digitals provides cross platform app development services, building apps that run on iOS and Android from one codebase.

Why Choose Stateside Digitals for
Cross-Platform App Development

Our Cross-Platform App
Development Services

As a full-service provider of cross platform app development services, we handle every stage of building your app, not just the parts that are easy to quote.
01.

Cross-Platform App Development with React Native

We build cross-platform apps using React Native, backed by a large, active developer community. One codebase runs natively on both iOS and Android, so you launch faster and spend less than building two separate apps.

02.

Cross-Platform App Development with Flutter

We also build with Flutter when it’s the better fit for your project. Flutter apps compile to native code on both platforms, giving you a consistent look and fast performance from a single codebase.

03.

Cross-Platform UI/UX Design

Our designers build interfaces that feel native on both iOS and Android, respecting each platform’s design conventions instead of forcing one look onto both.

04.

Cross-Platform App Modernization

If your app was built on an older hybrid framework, we can migrate it to React Native or Flutter, without pausing your releases or forcing a full rebuild from scratch.

05.

Wearable and Cross-Platform Companion Apps

We build companion apps that extend your cross-platform app to Apple Watch and Android wearables, designed for quick, glanceable interactions rather than a shrunk-down phone screen.

06.

Backend and Cloud Integration

Every cross-platform app needs a reliable backend behind it. We build and connect your app to cloud infrastructure on platforms like AWS, Google Cloud, and Firebase, handling authentication, data storage, and real-time syncing.

07.

Cross-Platform QA and Device Testing

A single codebase still has to work correctly on two different platforms with different devices and OS versions. We test across real iOS and Android devices, so your app doesn’t just work on the two you happened to test on.

08.

Cross-Platform Maintenance and App Store Optimization

After launch, we monitor performance, patch bugs, and keep your app updated as new iOS and Android versions roll out. We also offer app store optimization consulting to help your app get found on both stores.

How Much Does Cross-Platform
App Development Cost?

Cross-platform app development cost depends mainly on features, design complexity, and how many integrations your app needs. As a general guide:
01

Simple MVP apps

Core features and a basic design. These typically fall in the lower five-figure range.

02

Standard business apps

Custom UI, backend, user accounts, and integrations. These usually cost more and take longer to build.

03

Enterprise cross-platform apps

Security requirements, legacy integrations, and larger user bases. These sit at the higher end, often into six figures.

These are general market ranges, not a fixed Stateside quote. Your exact cost depends on your specific app, and we’ll give you a clear, itemized number after a short discovery call.

Cross-Platform vs. Native:
Which Should You Choose?

This is one of the first decisions most clients ask us about, and the honest answer depends on your goals.

Choose Cross-Platform When

You need to launch on both iOS and Android quickly, on a tighter budget, with one shared codebase. We build with React Native and Flutter for clients who need both platforms without doubling the development cost.

  • One shared codebase
  • Faster to both stores
  • Lower build cost

Choose Native When

You need deep hardware access, top performance, or platform-specific features that push past what a shared codebase handles well. Native development is also the better long-term choice if you’re only targeting one platform for now.

  • Deep hardware access
  • Best raw performance
  • Platform-specific features
If you’re not sure which fits your project, we’ll walk you through the tradeoffs on a call instead of just pushing whichever option we prefer to build.

How We Work

01Discovery

We learn your business, your users, and what success looks like for this app before writing a line of code.

02Design

Our designers map out the user experience and a UI that feels native on both iOS and Android, so you can see and test the app before development starts.

03Development

Our developers build your app using React Native or Flutter, with regular check-ins so you always know where the project stands.

04Testing

Every app goes through QA testing on real iOS and Android devices before it ships, so bugs get caught before your users find them.

05Launch and Support

We handle submission to both the App Store and Google Play, and stay on for maintenance, updates, and monitoring after launch.

Industries We Build Cross-Platform Apps For

We’ve built cross-platform apps for healthcare, fintech, retail, logistics, real estate, and other industries, each with its own compliance needs and user expectations.
A healthcare app has to handle patient data carefully on both platforms. A logistics app has to track vehicles and deliveries in real time, whichever phone the driver carries. We take the time to understand your industry’s rules before we start building.

What to Look for in a Cross-Platform
App Development Company

Not every cross platform app development company operates the same way, and picking the wrong one can cost you months and a rebuild. Here’s what’s worth checking before you sign anything:
01

Do they use a modern tech stack?

If a company is still building purely in older hybrid frameworks like Cordova or Ionic in 2026, they’re building on outdated foundations that show up as sluggish performance.

02

Do they test on real devices for both platforms?

A shared codebase can still behave differently on iOS and Android. A company that only tests on one platform, or only on emulators, is likely to miss bugs that show up on real phones.

03

Is pricing clear before you start?

A vague quote that “depends on scope” without real numbers is a red flag. Ask for an itemized estimate.

04

Do you keep ownership of your code?

Make sure your contract states clearly that you own the source code and both your App Store Connect and Google Play Console accounts, not the agency.

05

Is support included after launch?

An app that works on launch day can break months later when either Apple or Google releases a new OS update. Ask what happens after the contract ends.

Frequently Asked Questions

Do you build with React Native or Flutter?

We work with both React Native and Flutter and will recommend whichever fits your project best. React Native tends to be a strong fit if you want a large developer community and easy integration with existing JavaScript tools, while Flutter often edges ahead on raw UI performance and design consistency.
