Mobile App Development
How Much Does a Mobile App Cost to Build?
A mobile app costs $15,000–$60,000 (single platform) or $25,000–$120,000+ (cross-platform) in 2026. Project Cost Estimator's calculator factors in platform choice (React Native vs native), backend infrastructure, and app store requirements based on 600+ real projects.
Mobile app development is one of the most expensive software projects you can undertake. The gap between a $10,000 app and a $150,000 app comes down to platform choice, feature complexity, and backend requirements. Here is a clear breakdown for 2026.

A mobile app costs $10,000–$50,000 with a freelancer or $25,000–$150,000+ with an agency in 2026. Scopebit’s engine pegs the median freelancer mobile app at $30,000 and median agency mobile app at $87,500— apps fall into the custom-stack 2.5× multiplier band with +20 complexity, where geography swings the freelancer median from $16,500 (Eastern Europe 0.55×) to $43,500 (US 1.45×). Simple apps $10K–$25K; complex real-time/AI $60K–$150K+. Cross-platform (React Native, Flutter) saves 30–40% vs dual native. Based on Scopebit’s analysis of 600+ real projects across 6 markets.

Native vs Cross-Platform — The Defining Cost Decision
This is the single biggest cost decision for any mobile app project. Building native means two codebases (Swift for iOS, Kotlin for Android). Cross-platform means one codebase for both:
For 90% of mobile apps in 2026, React Native or Flutter is the right choice. The 30–40% cost savings over native development are significant, and the performance gap has narrowed to near zero for most use cases. Reserve native development for games, AR experiences, or apps that need deep hardware integration.
Backend Costs — The 40% You Forget to Budget
Every mobile app needs a backend — APIs, databases, user management, push notifications, and file storage. Backend development typically costs 30–50% of the total project budget. Here is what different backend architectures cost:
Hosting: $0–$200/mo · Great for MVPs. Auth, database, storage, push notifications included. Limits appear at scale.
Hosting: $50–$500/mo · Full control, custom business logic. Required for complex apps or specific compliance needs.
Hosting: $200–$2,000/mo · Separate services for auth, payments, messaging. Scales independently. Complex to build and maintain.
App Store Fees and Submission
Getting your app on the stores has both upfront and ongoing costs. Apple charges a $99/year developer fee. Google charges a one-time $25 fee. Both take a 15–30% commission on in-app purchases and subscriptions.
Apple's review process takes 1–3 days for initial submissions and can result in rejections. Budget 2–4 weeks for the full submission process, especially for first-time submissions. Common rejection reasons include incomplete metadata, privacy policy issues, and guideline violations. An experienced developer will know how to avoid these, but expect at least one round of revisions.
For subscription-based apps, the store commissions are a significant ongoing cost. At $10/month per user with 1,000 subscribers, Apple takes $1,500–$3,000/month in commissions. Factor this into your pricing model from day one.
Native vs Cross-Platform: Real Cost Tradeoffs
The native-vs-cross-platform debate has shifted in 2026. Performance parity is closer than ever, hiring pools have flipped, and the economics favor one codebase for most teams. Here is the unvarnished tradeoff analysis most calculators skip.
Cost comparison at a glance
| Approach | Single platform | iOS + Android | Time to launch | Performance | Maintenance |
|---|---|---|---|---|---|
| Native (Swift + Kotlin) | $25K–$60K | $50K–$120K (2 codebases) | 4–6 months | Best | 2x cost (2 teams) |
| React Native | $20K–$45K (both platforms) | $20K–$45K | 2.5–4 months | Good | Single team |
| Flutter | $22K–$50K (both platforms) | $22K–$50K | 2.5–4 months | Very Good | Single team |
| Capacitor / Ionic | $15K–$35K (both platforms) | $15K–$35K | 2–3 months | OK for content apps | Single team |
When native makes sense
- ●Apps requiring deep platform integration (ARKit, advanced camera pipelines, BLE peripherals)
- ●High-performance gaming or AR/VR where every frame counts
- ●Apps competing on UX polish (banking, social, premium consumer products)
- ●Long-term apps with a 5+ year roadmap — native compounds value over time
When cross-platform makes sense
- ●MVPs and proof-of-concepts where time to market dominates
- ●Content-heavy apps (news, social feeds, e-commerce browsing)
- ●B2B tools where UX polish matters less than shipping speed
- ●Limited budgets — one team, one codebase, half the hiring effort
Real cost drivers most calculators ignore
Required to publish on the App Store — non-negotiable.
One lifetime fee, no annual renewal.
Plan release cadence around review windows; rejections add weeks.
Mobile apps are thin clients — the backend is where the real work lives. Similar to a typical web app backend.
Firebase Cloud Messaging is free up to scale; OneSignal and Airship charge by MAU.
Sentry, Firebase Crashlytics, Mixpanel. Mandatory, not optional.
Most teams forget this. Screenshots, keywords, localized metadata — your app will not be found without it.
My recommendation
For 80% of apps in 2026, React Native or Flutter is the right choice. You ship 2–3x faster, hire from a bigger talent pool, and maintain one codebase. Choose native only when platform-specific performance or features genuinely matter to your users — not because "native feels more professional."

Frequently Asked Questions
How much does it cost to develop a mobile app?
A mobile app costs $10,000–$50,000 with a freelancer or $25,000–$150,000 with an agency in 2026. Simple apps (5–10 screens, basic features) cost $10,000–$25,000. Medium-complexity apps with user accounts, payments, and push notifications cost $25,000–$60,000. Complex apps with real-time features, AI, or marketplace functionality cost $60,000–$150,000+.
Should I build native or cross-platform?
Cross-platform (React Native or Flutter) costs 30–40% less than building separate iOS and Android apps. Native development costs $40,000–$150,000 (building twice) vs $25,000–$90,000 for cross-platform. Choose native only if you need maximum performance, complex animations, or deep OS-specific integrations.
What are the ongoing costs of maintaining a mobile app?
Annual app maintenance costs $5,000–$20,000, covering OS updates, bug fixes, security patches, and minor features. Apple Developer Program costs $99/year, Google Play costs $25 one-time. Backend hosting adds $50–$500/month. Budget 15–20% of the initial build cost per year for maintenance.
How long does it take to build a mobile app?
A simple app takes 8–12 weeks. A medium-complexity app takes 12–20 weeks. A complex app takes 20–40 weeks. Add 2–4 weeks for app store review and approval. Cross-platform development is typically 20–30% faster than building two native apps.
How much do app store fees cost?
Apple charges a $99/year developer fee plus 15–30% commission on in-app purchases and subscriptions (15% for developers earning under $1M/year). Google charges a $25 one-time fee plus 15–30% commission. For subscription apps, these commissions are a significant ongoing cost — budget accordingly.
