Every platform, one product, nothing built twice
Your customers are on iPhones, Android phones, tablets, and the web, and they expect the same experience on all of them. We build cross-platform applications from shared code, choosing the framework that fits your product rather than the one we happen to prefer, and we launch on every platform with the marketing to match.
The right shared-code stack for your roadmap
Cross-platform isn't one technology. It's a set of choices, and the right one depends on what your app has to do in year three, not just year one.
Book a strategy session ($350)A good fit if you
- Need to reach iOS, Android, and possibly web and desktop on one budget
- Want a single team and release process instead of parallel builds
- Have a product that's mostly workflow, content, and data
- Plan to ship features often and want them to land everywhere at once
- Want an honest recommendation between the frameworks rather than a pitch for one
Cross-platform app development means writing most of your application once and deploying it to multiple platforms: iOS, Android, and often web and desktop. The modern frameworks render native-quality interfaces and let us drop into native code wherever a feature needs it. Done well, you get one codebase, consistent behavior everywhere, and a fraction of the maintenance cost of separate apps.
The two leading frameworks are React Native, from Meta, and Flutter, from Google. React Native fits teams with web React experience and apps built around standard UI and data. Flutter excels at highly custom, animation-rich interfaces and extends cleanly to web and desktop from the same code. There are other paths for specific situations, including progressive web apps where a store presence isn't needed. We choose after we understand your product, and we explain why.
We handle the complete lifecycle: platform strategy and framework selection, UI/UX that respects each platform's conventions, architecture, development, native integration where needed, AI features, testing across devices, submission to every store, and ongoing support through each platform's update cycle.
What we build across platforms
One product, deployed everywhere your customers are, with native depth where the experience depends on it.
Tools and stack we work in
- React Native
- Flutter
- Dart
- TypeScript
- Expo
- Progressive Web Apps
- Firebase
- Supabase
- Stripe
- Swift
- Kotlin
- Fastlane
- Codemagic
We're fluent in both major frameworks and recommend by fit, not habit. The decision document we give you explains the trade-offs in plain terms so you understand what you're choosing.
-
iOS and Android apps from shared code
Customer, field, and enterprise applications shipped to both stores from one codebase in React Native or Flutter.
-
Mobile plus web from one product
Applications that run as native mobile apps and as a web app from the same code, so the customer portal and the phone app never drift apart.
-
Desktop extensions
Where staff work at a desk, the same product on Windows and macOS through Flutter or web technologies.
-
Platform strategy and framework selection
A written recommendation, with reasoning, on React Native, Flutter, native, or a progressive web app for your specific product and roadmap.
-
Native integration
Swift and Kotlin modules for camera, payments hardware, Bluetooth, background tasks, and platform features the shared layer shouldn't carry.
-
AI-powered features
Search, recommendations, document capture, assistants, and personalization built once and deployed to every platform.
-
Multi-store launch and growth
Listing optimization for the App Store and Google Play, web deployment, analytics, and install campaigns across platforms.
Where cross-platform is the smart money
Products where reaching everyone matters more than platform-specific polish, and where the roadmap is long enough that maintenance cost decides the economics.
Multi-location service businesses
Customer booking on every phone, staff apps on whatever the team carries, and a manager web dashboard, all from one product and one release.
Insurance and financial services
Policyholder apps and portals that behave identically on iPhone, Android, and web, with shared business logic and compliance controls.
Healthcare and practices
Patient apps and clinician tools across phones, tablets, and desktop within privacy requirements, from a single codebase.
E-commerce and marketplaces
Shopping on mobile and web from one product, with consistent catalog, cart, checkout, and account behavior everywhere.
Education, content, and membership
Courses, media, and community delivered to every device with progress synced across all of them.
Startups and new products
The widest reach for the least capital, so real users on every platform shape the product before a larger investment.
Why the framework choice is a business decision
We've watched companies choose a mobile stack because a developer liked it, then pay for that preference for years in maintenance, hiring, and features that were hard to ship. The framework decision determines your costs, your speed, and who you can hire long after launch. We treat it with the seriousness that deserves, and we write the recommendation down so you can hold us to the reasoning.
The goal is always the same as everything else we do: the most customers reached, converted, and retained for the money spent. For most business apps, cross-platform gets you there faster and cheaper than separate native builds. When it doesn't, we say so. Then we launch on every platform with the campaigns and store optimization that turn a build into a user base.
How we work
-
Discovery and scope
What the app has to do for the business, who uses it, and what it replaces. We write the scope before we quote it, so the quote holds.
-
Design and architecture
UI/UX in your brand, an architecture chosen for your roadmap, and a data model that won't need rebuilding in year two.
-
Build and test
Sprint-based development, AI integration where it earns its place, and testing on real devices before submission.
-
Launch and grow
Store submission, analytics, crash monitoring, and the part most dev shops skip: the marketing plan that gets it downloaded.
The same standards as everything else we do
You own the code and the IP
Repositories, store accounts, certificates, and design files are registered to you from day one.
Scoped before it's quoted
We write down what the app does before we tell you what it costs, so the number doesn't drift.
Senior people, always
The architect in the first call is the one reviewing every pull request.
Built to be marketed
We're the agency that also runs your app install campaigns, ASO, and launch. Most dev shops hand over the build and leave. It's how we work.
Complete lifecycle
Planning, UI/UX, architecture, development, AI integration, testing, deployment, and ongoing support under one roof.
Three languages
English, Spanish, and Portuguese in the UI, the store listing, and the support flow, for the markets where we operate.

Questions we get asked
React Native fits teams with web React skills and apps built around standard UI and data flows. Flutter fits highly custom, animation-rich interfaces and extends more cleanly to web and desktop. We recommend after understanding your product, team, and roadmap, and we explain the trade-offs in writing.
Not for most business apps. Modern frameworks render native-quality interfaces and let us use native code where it matters. For graphics-heavy or deeply hardware-dependent apps, native still wins, and we'll tell you if yours is one.
Yes, with Flutter or with React Native paired with React for web. Shared business logic and design across mobile and web is one of the strongest reasons to choose cross-platform for products with a portal component.
Typically a large share of both initial build and ongoing maintenance compared with separate native apps, since most code is written once. We estimate both paths in the strategy session so the saving is specific to your app.
A web application that installs to the home screen and works offline without going through an app store. It fits when store presence isn't important and the app is mostly content and forms. It doesn't fit when you need deep device features or push notifications on iOS.
You do. Repositories, store accounts, signing credentials, and design files are registered to you from the start, whichever framework we use.
Every platform. One product. One honest recommendation.
