Cross-Platform iOS & Android App Development
One project, both stores — iOS and Android built together from a single codebase, starting at $6,500.
Why "build iOS first, Android later" rarely works
- Building for iOS and Android separately means two timelines, two budgets, and two codebases to maintain going forward.
- Most small businesses can't choose one platform — your customers are on both, and the 30% on the platform you didn't pick still matter.
- Cross-platform frameworks have gotten mature, but only if someone knows how to use them correctly — otherwise you get lowest-common-denominator UX.
What cross-platform development includes
- Native UX on both platforms from a single React Native codebase. <a href="/react-native-vs-flutter/" class="link-accent">Why React Native? See how React Native compares with Flutter →</a>
- App Store (iOS) and Google Play (Android) submission handled together.
- One project, one invoice, one timeline — not two sequential builds.
- 60-day post-launch support included on both platforms.
- Full source code delivery — you own everything.
- App Store and Play Store listing management included.
How it works
1
Discovery
App spec, data model, API requirements, store account setup.
2
Design
UI mockups for iOS + Android — same design language, platform-appropriate patterns.
3
Build
Iterative with staging builds you can run on your own device.
4
Launch
Both store submissions simultaneously, approval support.
Frequently asked questions
Why React Native instead of Flutter?
React Native uses JavaScript and leans on native platform components — apps feel native because they use the real iOS and Android UI elements. It also integrates naturally with PHP back-ends and the rest of the ArdinGate stack. For a full breakdown of the tradeoffs, see the <a href="/react-native-vs-flutter/" class="link-accent">React Native vs Flutter comparison →</a>
Does a cross-platform app feel as good as a fully native app?
For 95% of app categories — yes. The scenarios where native is meaningfully better are high-performance games, AR/VR applications, and apps that need deep OS integration (like a system-level keyboard or camera app). Companion apps, booking tools, client portals, and business utility apps are all well-served by cross-platform.
What does the entry price include?
Native apps start at $6,500 for a Business Utility app (5–8 screens, both stores). If you already have a website, a companion app ($7,500–$10,000) mirrors it instead: up to 4 screens that mirror your existing website, REST API integration with your site, App Store and Play Store submission, and 60 days of post-launch support. Push notifications ($300–$700), offline mode ($800–$2,000), login (from $600), and in-app payments ($700–$1,200) are add-ons; ongoing maintenance is billed monthly ($150–$300/mo).
How long does it take?
A focused 5-screen companion app typically takes 6–8 weeks from a signed spec to store submission. Add 1–2 weeks for Apple's review process and 1–3 days for Google Play. More complex apps take 10–16 weeks.
