- Cross-platform frameworks promise big savings over native development — but how big, really?
- Here is a realistic total-cost comparison including the maintenance years nobody budgets for.
Every app project faces the same early fork: build separately for iOS and Android in their native languages, or build once with a cross-platform framework. The choice shapes the budget not just at launch but for every year the app lives. Here is what the numbers really look like in 2026.
Build Cost: The Headline Difference
Two native apps do not cost exactly double one cross-platform app, because design, backend, project management and QA are shared either way. In practice, cross-platform saves 30–45% on the initial build. For a mid-complexity product quoted at $80,000 native-both-platforms at Western rates, expect roughly $45,000–$55,000 in Flutter or React Native.
The Three-Year View Matters More
Apps typically cost 15–25% of their build price per year in maintenance: OS updates, store policy compliance, library upgrades, bug fixes and small features. Native doubles much of that work — two codebases mean two sets of updates, two test passes, and often two specialist developers on retainer.
| Cost item (illustrative, mid-complexity) | Native iOS + Android | Cross-platform |
|---|---|---|
| Initial build | $80,000 | $50,000 |
| Maintenance × 3 years | $48,000 | $27,000 |
| Three-year total | $128,000 | $77,000 |
Outsourcing shifts every number down by half or more, but the ratio between the columns holds.
Where Native Still Earns Its Premium
- Apps pushing hardware limits: pro camera tools, AR, Bluetooth medical devices, high-end games.
- Products where each platform needs a genuinely different experience.
- Teams with existing native codebases and specialists already on staff.
Hidden Costs People Forget on Both Paths
- Backend and API development — often a third of the total budget.
- App store accounts, signing certificates and release management.
- Analytics, crash reporting and push notification services.
- Design updates when iOS and Android ship visual refreshes.
Frequently Asked Questions
Is cross-platform quality good enough for serious products?
Yes — banking apps, airline apps and top e-commerce apps ship on Flutter and React Native today. For standard business functionality, users cannot tell the difference.
Can I start on one platform native and add the other later?
You can, but you will pay the full second build later. If both platforms are on the roadmap, going cross-platform from day one is nearly always cheaper.
