How much does it cost to build a mobile app? 7 factors that shape pricing

How much does it cost to build a mobile app? This question has a much wider range of answers than website pricing. A mobile app is an end-to-end investment that includes UI design, backend API, notification infrastructure, App Store and Google Play approval processes, and post-launch updates. In this article, we cover the factors that determine mobile app cost, platform options, hidden expenses, and practical ways to keep your budget under control.

Why is mobile app cost so variable?

Although a simple informational app and a payment-enabled marketplace app are both labeled “mobile apps,” development effort can differ by a factor of ten. Agencies usually calculate pricing based on feature list (user stories), number of platforms, and backend complexity. Clarifying scope before asking for a single number directly improves quote quality.

7 factors that determine mobile app price

1. Platform choice: iOS, Android, or both

Building for iOS only, Android only, or both has different cost implications. Cross-platform approaches such as React Native and Flutter can publish to both stores from one codebase and reduce budget. However, projects requiring intensive camera usage, BLE, AR, or low-latency audio/video may be better served by native (Swift/Kotlin) development.

Approach	Advantage	Disadvantage	Best for
Native (Swift + Kotlin)	Highest performance, full platform API access	Two separate codebases, higher cost	AR, gaming, graphics-heavy projects
React Native / Flutter	Single team, fast iteration, shared business logic	Some native module bridges may be needed	MVPs, B2C apps, standard corporate apps
Hybrid (WebView-based)	Lowest initial cost	Performance and store rejection risk	Simple content apps (limited)

2. Feature scope: MVP or full product?

Each additional module increases design, development, and testing time. Common modules and cost impact:

• Sign-up / login: Email, phone OTP, social login (Google, Apple Sign-In)
• Profile management: Avatar, preferences, address book
• Payments: iyzico, Stripe, App Store / Play Store in-app purchase
• Map & location: Google Maps, live location tracking, geofencing
• Push notifications: Firebase Cloud Messaging, segment-based campaigns
• Offline mode: Local database, sync conflict management
• Admin panel: Web-based management interface, reporting
• Chat / messaging: Real-time WebSocket, media sharing

Using an MVP (Minimum Viable Product) approach—launching a single core user flow first and planning the rest based on data—is the most effective way to control mobile app cost.

3. Backend and API architecture

A mobile app does not run alone. User data, content, business rules, and payment flows live on the server side. Backend options:

• Ready BaaS (Firebase, Supabase): Fast start, low initial cost; scaling and customization limits exist.
• Custom API (Node.js, Python, Go): Full control, ERP/CRM integration possible; higher development and maintenance cost.
• Existing system integration: Connecting to corporate ERP or legacy APIs requires additional testing and documentation.

4. UI/UX design depth

From wireframes to a high-fidelity UI kit, design effort directly affects mobile app pricing. In App Store and Google Play environments, users are highly sensitive to visual quality; low design quality increases uninstall rates after download.

5. Third-party service integrations

Each integration introduces its own development, testing, and licensing cost:

• Payment: iyzico, PayTR, Stripe
• Maps: Google Maps Platform (API usage fee)
• SMS verification: Netgsm, Twilio
• Analytics: Firebase Analytics, Mixpanel, Amplitude
• Crash reporting: Sentry, Crashlytics

6. Testing, QA, and device compatibility

Different screen sizes (from iPhone SE to iPad Pro), Android OEM fragmentation, and OS version compatibility require comprehensive testing. Allocate budget for store rejection scenarios as well (App Store Review Guidelines, Google Play Policy).

7. Post-launch maintenance and updates

iOS and Android release a major version yearly; SDK updates, security patches, and changing store policies create recurring maintenance cost. A common planning rule is to budget annual maintenance at 15–25% of initial development cost.

Common mobile app project profiles in 2026

Simple informational / showcase app

Static content, about page, contact form, basic notifications. Shortest delivery timeline, typically 4–8 weeks.

Reservation or appointment app

Calendar integration, payments, push notifications, admin panel. Mid-segment project; both user and business interfaces are designed together.

Marketplace app

Two-sided users (buyer + seller), payments, commission, ratings, messaging. Upper segment; liquidity and trust mechanisms are critical.

Corporate B2B mobile product

Role-based access, offline sync, ERP/CRM integration, reporting. Operates at software project scale; discovery tends to be longer.

App Store and Google Play costs

Besides development, account for store registration and commission expenses:

• Apple Developer Program: 99 USD per year
• Google Play Console: 25 USD one-time
• In-app purchase commission: Apple and Google 15–30% (revenue-based)
• Payment infrastructure commission: iyzico/Stripe percentage + fixed fee per transaction

Mobile app development process and timeline

1. Discovery & scope (1–2 weeks): User stories, wireframes, MVP boundary
2. UI/UX design (2–4 weeks): Screen design, prototype, user testing
3. Development (4–12 weeks): Frontend, backend, integrations
4. Testing & QA (1–2 weeks): Device testing, beta, store rejection fixes
5. Launch (1 week): Store listing, screenshots, metadata, approval

Beware the “cheap mobile app” trap

Very low-priced quotes often exclude:

• Backend and security infrastructure
• KVKK compliance and privacy policy
• Store release support and revision after rejection
• Source code transfer
• Post-launch maintenance and SDK updates

Gaps discovered after store release often cost more than building the right scope from the start.

5 ways to keep cost under control

1. Start with MVP: Launch one primary flow first; plan the rest based on cohort data.
2. Create a priority matrix: Clearly document “must-have” vs. “phase 2” items in writing.
3. Test prototypes: Collect feedback from 5–10 users with a Figma prototype before coding.
4. Define metrics: Downloads, sign-ups, DAU, payment conversion—do not invest in features you cannot measure.
5. Evaluate cross-platform: If native is not required, React Native or Flutter can cut budget significantly.

Frequently asked questions

How much does it cost to build a mobile app?

The exact figure depends on scope. There is a large gap between a simple showcase app and a marketplace app. Prepare your feature list and request scope-based quotes from at least two vendors.

Should iOS or Android launch first?

Check your target audience device distribution. Android share is high in Turkey; iOS can be priority in global B2B. A common MVP strategy is single-platform first with a cross-platform roadmap.

Is a mobile app better than a website?

If you need push notifications, offline access, camera/sensor usage, or app store discoverability, yes. For information-only use cases, a responsive website or PWA may be enough.

How much is mobile app maintenance?

Plan roughly 15–25% of initial development cost per year. This includes SDK updates, OS compatibility, security patches, and small feature enhancements.

Freelancer or agency?

A freelancer can be suitable for a low-budget MVP. For projects requiring enterprise security, SLA, team continuity, and complex integrations, an agency is preferable.

Conclusion

Mobile app cost is the sum of platform, scope, backend, design, and maintenance components. By asking the right questions, starting with MVP, and comparing quotes based on scope, you can avoid budget surprises.
