A mobile app costs $60,000 to $120,000 for a single-platform MVP, $90,000 to $180,000 for a cross-platform app with a backend and payments, and $200,000 to $400,000+ for feature-rich or regulated applications. Cross-platform development with Flutter or React Native typically reduces cost by 30–40% versus building twice natively. Below is the feature-by-feature breakdown, the regional rate picture, and the ongoing costs that most first-time budgets omit.
Key Takeaways
- MVP: $60,000–120,000. Production cross-platform app: $90,000–180,000. Complex or regulated: $200,000–400,000+.
- Cross-platform saves 30–40% on build cost, not because rates are lower but because you write the app once.
- Roughly 40–50% of total cost is the backend, not the app itself. Budgets that only count screens are wrong by half.
- Timeline: 3–5 months for an MVP, 5–8 months for a production app, plus store review.
- Ongoing costs run 15–25% of build cost per year, and start the day you launch — not a year later.
- The feature that most reliably blows a budget is offline synchronisation, followed by real-time messaging and payment compliance.
Cost by App Type
| App type | Cost range | Timeline | Typical scope |
|---|---|---|---|
| Simple / informational | $30,000–60,000 | 2–3 months | Content display, forms, basic auth, no custom backend |
| MVP (single platform) | $60,000–120,000 | 3–5 months | Core flow, auth, simple backend, analytics |
| Cross-platform production app | $90,000–180,000 | 4–7 months | iOS + Android, custom backend, payments, admin panel |
| Marketplace / two-sided | $180,000–350,000 | 7–12 months | Dual user types, matching, payments, ratings, messaging |
| On-demand / logistics | $200,000–400,000 | 8–14 months | Real-time tracking, dispatch, maps, driver and customer apps |
| Fintech / healthcare | $250,000–500,000+ | 10–18 months | Above plus PCI DSS, HIPAA or PSD2 compliance work |
| Enterprise internal app | $80,000–250,000 | 4–10 months | SSO, legacy integration, offline support, MDM distribution |
Cost by Feature
This is the more useful table. Hours assume a competent mid-to-senior team and include design, implementation and testing for a cross-platform build.
| Feature | Hours | Cost at $70/hr | Cost at $130/hr |
|---|---|---|---|
| User registration + login (email) | 40–60 | $2,800–4,200 | $5,200–7,800 |
| Social / SSO login | 20–40 | $1,400–2,800 | $2,600–5,200 |
| User profiles + settings | 40–70 | $2,800–4,900 | $5,200–9,100 |
| Onboarding flow | 30–50 | $2,100–3,500 | $3,900–6,500 |
| Search + filtering | 60–120 | $4,200–8,400 | $7,800–15,600 |
| Push notifications | 30–50 | $2,100–3,500 | $3,900–6,500 |
| In-app payments (Stripe) | 60–110 | $4,200–7,700 | $7,800–14,300 |
| Subscriptions + store billing | 80–140 | $5,600–9,800 | $10,400–18,200 |
| Real-time chat | 120–220 | $8,400–15,400 | $15,600–28,600 |
| Maps + live location tracking | 100–200 | $7,000–14,000 | $13,000–26,000 |
| Offline mode + sync | 160–320 | $11,200–22,400 | $20,800–41,600 |
| Media upload + processing | 70–130 | $4,900–9,100 | $9,100–16,900 |
| Video / audio calling | 140–260 | $9,800–18,200 | $18,200–33,800 |
| Admin dashboard | 120–250 | $8,400–17,500 | $15,600–32,500 |
| Analytics + event tracking | 30–60 | $2,100–4,200 | $3,900–7,800 |
| AI feature (LLM integration) | 80–200 | $5,600–14,000 | $10,400–26,000 |
| Localisation (per language) | 20–40 | $1,400–2,800 | $2,600–5,200 |
Offline sync is bolded deliberately. It is the single most underestimated feature in mobile development. Users expect the app to work on a train; delivering that means conflict resolution, queued mutations, local persistence and a reconciliation strategy. Teams routinely scope it at 40 hours and spend 250. If your app genuinely needs offline capability, scope it as a first-class architectural decision, not a feature.
Where the Money Actually Goes
A common and expensive misconception is that an app’s cost is the cost of building screens. On a typical project the split is:
| Component | Share of budget |
|---|---|
| Backend / API development | 30–40% |
| Mobile client (iOS + Android) | 30–40% |
| UI/UX design | 10–15% |
| QA and testing | 10–15% |
| DevOps, CI/CD, release infrastructure | 5–10% |
| Project management | 8–12% |
If a vendor’s quote is dramatically lower than others, the usual explanation is that it covers the middle row and nothing else. The backend, testing and release work still has to happen — it has just been moved onto you or deferred into a change order.
Native vs Cross-Platform
| Native (Swift + Kotlin) | Flutter | React Native | |
|---|---|---|---|
| Relative build cost | Baseline (100%) | 60–70% | 60–70% |
| Codebases to maintain | 2 | 1 | 1 |
| Performance ceiling | Highest | Very good | Very good |
| Access to new OS features | Immediate | Slight lag | Slight lag |
| Best for | Graphics-heavy, deep OS integration, AR | Consistent custom UI across platforms | Teams with existing React expertise |
| Talent availability | Good | Good | Excellent |
Choose cross-platform — which is the right answer for most business apps — when your app is fundamentally about data, forms, lists, media and transactions. Flutter delivers a genuinely production-grade result for this class of application at meaningfully lower cost, and React Native is the natural fit if your web team already writes React.
Choose native when you need sustained high-frame-rate graphics, heavy background processing, deep integration with platform-specific hardware, ARKit or Core ML work, or when you are building for one platform only and expect to stay there. Our iOS and Android teams still build native where the requirements justify it.
The nuance people miss: cross-platform does not mean zero platform-specific work. Expect 10–20% of effort to remain platform-specific for store compliance, permissions, notifications and native module integration.
Regional Rate Comparison
| Region | Mid-level mobile dev | Senior mobile dev | Relative MVP cost |
|---|---|---|---|
| United States | $110–150/hr | $145–195/hr | 100% |
| Canada | $80–110/hr | $105–140/hr | 70–78% |
| United Kingdom | £70–95/hr | £90–125/hr | 75–85% |
| Western Europe | €70–100/hr | €95–130/hr | 75–88% |
| Eastern Europe | €38–55/hr | €55–80/hr | 40–50% |
| Latin America | $42–60/hr | $60–85/hr | 40–52% |
| South / Southeast Asia | $28–42/hr | $42–62/hr | 28–38% |
A US buyer choosing an Asian team saves roughly 65% on rate. Whether that translates to 65% off the project depends entirely on timezone overlap, communication quality and rework rate. A fuller regional picture across all roles is in our 2026 software development rate guide.
The Costs After Launch
Launch is the beginning of the spending, not the end of it.
Fixed platform costs
- Apple Developer Program: $99/year
- Google Play Developer: $25 one-time
- Code signing, provisioning: included above
Infrastructure, monthly
- Backend hosting: $100–500 early, $500–5,000+ at scale
- Database: $50–500
- File/media storage and CDN: $20–400
- Push notifications: free to $200
- Crash reporting and monitoring: $0–300
- Analytics: $0–500
Ongoing engineering
- Maintenance and updates: 15–25% of build cost annually
That last figure is not padding. iOS and Android each ship a major release annually with deprecations and permission changes; ignoring two cycles typically means an app that fails review or crashes on new devices. Dependencies reach end of life. Security advisories accumulate. Our application support and maintenance engagements exist almost entirely because teams discovered this in year two rather than budgeting for it in year one.
Also budget for: app store optimisation, user acquisition (frequently larger than the build cost), customer support tooling, and payment processing fees — including Apple and Google’s 15–30% commission on in-app digital purchases, which can dwarf every other line item in a subscription business.
Five Ways to Genuinely Reduce Cost
- Cut features, not quality. Ship six features that work rather than fifteen that mostly do. Every deferred feature is money you keep and a decision you get to make with real user data.
- Invest in discovery. Two to four weeks of structured discovery costs $8,000–20,000 and routinely removes more than that from the build by preventing rework.
- Choose cross-platform unless you have a specific reason not to. This is the largest single lever available.
- Use proven services rather than building infrastructure. Auth, payments, push, search and analytics are solved problems. Building your own auth system is a five-figure decision with no upside.
- Design a real MVP. Not a broken version of the full product — the smallest complete thing that delivers value to one clearly defined user.
What does not reduce cost: skipping QA, skipping design, or choosing a vendor purely on rate. Each of those reliably increases total spend.
How NSDBytes Approaches Mobile Estimation
We scope mobile projects feature by feature, using ranges with stated assumptions rather than a single number designed to win the deal. In practice:
- We separate the backend estimate from the app estimate, because conflating them is how budgets go wrong.
- We flag the expensive features early — offline sync, real-time, video, compliance — so you can make an informed call before they are baked into the plan.
- We phase delivery, targeting a working store-ready build early and expanding from there.
- We quote maintenance up front, as a line item, not a surprise.
If you want a scoped estimate for a specific app rather than a range from a table, our mobile app development team will work through it with you.
Final Thoughts
The gap between a $60,000 app and a $300,000 app is rarely ambition — it is the backend, the compliance surface, and whether the hard features (offline, real-time, payments) are genuinely required. Scope those three deliberately and the budget becomes predictable.
