Cross-platform app development
One codebase. Both app stores.
Flutter or React Native, compiled to native performance — not a web page wrapped in an app shell. One codebase reaches iPhone and Android together, typically for 30–40% less than building each one natively, with one team to maintain it afterwards.
- Cross-platform MVP from $12,500
- Built in 10–14 weeks
- One codebase, both stores
Three reasons people come to us for a cross-platform build.
You need both stores, and you need them now.
Waiting for two separate native builds to both finish isn't an option — you need iPhone and Android users covered from the same launch day.
The budget has to cover both platforms.
Two native teams building the same app twice was never going to fit the number you were given to work with.
Your team already lives in JavaScript.
React and web skills you already have translate directly into React Native, instead of starting two new native stacks from zero.
Starting prices, so you can plan.
- One codebase, both stores
- Flutter or React Native
- Typically 10–14 weeks
Typically, once the MVP has proven itself.
- More screens and integrations
- Both store listings optimised
- Typically 14–22 weeks
React Native or Flutter code shared with a web app.
- One codebase, multiple surfaces
- Faster to keep everything in sync
- Dedicated team available
Everything a cross-platform app needs, on either framework.
Always included
- A written scope and a fixed price before we start
- UX/UI design, consistent across both platforms
- Flutter or React Native development, senior engineers only
- QA on real iOS and Android devices
- App Store and Play Store submission — both listings prepared, both reviews handled
- Analytics and crash reporting
- 30 days of post-launch support
- Full ownership of the code and both store accounts
Add when you need it
- Maintenance and OS-update support from $490/mo
- Backend and API development
- A native module for one platform-specific feature
- A web version sharing the same codebase
Flutter or React Native — the honest way to choose.
Both compile to real, native-performance apps. Which one fits is less about which is "better" and more about what you're starting from and what you value in the interface.
| Choose | When |
|---|---|
| Flutter | You want design-heavy, highly custom UI and pixel-consistent behaviour across iOS and Android. |
| React Native | Your team already lives in JavaScript and React, or you want to share code with an existing web app. |
We’ll recommend one in the proposal, with the reasoning attached — not just the name of a framework.
A compiled app, not a website wearing an app icon.
A genuine cross-platform app compiles down to native components and runs at native speed — it's not a browser window pretending to be an app. That distinction matters, because a "hybrid" built as a WebView wrapped around a website can look similar in a screenshot and feel completely different the moment you touch it.
- Ask what compiles to native components versus what renders in an embedded browser
- Test scroll and gesture responsiveness in person, not from a demo video
- Check whether it works properly with no internet connection at all
- Ask which store review guidelines it's actually built to satisfy — Apple rejects thin WebView wrappers
One codebase, both stores, roughly 30–40% less.
Building native iOS and native Android separately means two codebases, two sets of bugs, and two teams' worth of ongoing maintenance. A cross-platform build shares the logic, the fixes and most of the interface across both — which is where the 30–40% saving against two native builds actually comes from, not from cutting corners. One team keeps it running afterwards, too, instead of two.
And when we'd tell you to go native instead.
Cross-platform isn't the right answer for everything, and we'll say so rather than force it. It shows its limits on deep platform APIs that framework bridges haven't caught up to yet, and on day-one access to brand-new OS features Apple or Google ship before the cross-platform tooling supports them.
- Deep, platform-specific hardware or OS integration a bridge can't fully reach
- Needing a brand-new OS feature on day one, before framework support catches up
- Heavy AR, background-precision or watch-app work, best done natively
- When any of that applies, we'll recommend native — even though it's a smaller number for us
From scope to both stores.
Scope
A scoping call and workshop: the core flow, Flutter or React Native, and what "done" means on both platforms. You get a written scope and a fixed price.
Design
One set of UI screens, designed to feel native on both iOS and Android, reviewed as real screens before any code is final.
Build in sprints
Development on a build you can install on either platform as it grows, with a working version to react to every couple of weeks.
Launch
Submission to both stores, review handled on each, then we watch the first week of real usage across both.
Typical timeline: cross-platform MVP 10–14 weeks; full product 14–22 weeks. What moves it: how much of the interface needs custom platform-specific polish.
Cross-platform apps we've built.
Camera, GPS, push, biometrics — all still there.
Going cross-platform doesn't mean giving up device capabilities. Flutter and React Native both reach the hardware and platform APIs that matter for the vast majority of business apps, through the same plugins used across thousands of production apps.
- Camera, photo library and file access
- GPS and location services
- Push notifications on both platforms
- Face ID, Touch ID and Android biometric authentication
- A native module written just for one platform, when one specific feature needs it
When one platform needs to go fully native.
