How much does custom app development cost?

Cross-platform MVP: €15,000-€25,000. Native iOS + Android app: €30,000-€50,000. Complex app (marketplace, real-time, integrations): €50,000-€100,000+. Includes: UX/UI design, development, backend, QA, store publishing, 3 months support.

Is native or cross-platform better?

Cross-platform (React Native, Flutter) if budget is limited and you need iOS + Android quickly. Native (Swift, Kotlin) if you need maximum performance (gaming, AR, video) or specific iOS/Android features. For 80% of B2B/B2C cases, cross-platform works perfectly.

How long does it take to publish on the stores?

Average app development: 3-4 months. Testing and beta: 2-3 weeks. Store submission: Apple review 2-7 days, Google 1-3 days. Total timeline: 4-5 months from kickoff to public release.

Do you also manage backend and API integrations?

Yes, 100%. We develop the complete backend (Node.js, Python, NestJS), database (PostgreSQL, MongoDB), REST/GraphQL APIs, third-party integrations (CRM, payments, analytics, push notifications). Not just the frontend.

Who owns the source code?

You do. We provide the complete source code (app + backend), Git repository access, and technical documentation. No vendor lock-in. You can continue development internally or with other providers.

Do you provide maintenance and updates?

Yes. It includes 3 months of post-launch support (bug fixing, minor tweaks). Then monthly maintenance SLAs from €500/month: OS updates (new iOS/Android), bug fixes, minor evolutions, crash monitoring.

How do you handle privacy and security?

Secure JWT authentication, mandatory HTTPS, sensitive data encryption (AES-256), GDPR compliance (privacy policy, consents, data deletion), OS permissions (location, camera, notifications) only when necessary. Pre-launch security audit.

Can we start with an MVP?

Yes, recommended. MVP with core features (10-15 screens) in 2-3 months, budget €15,000-€25,000. Release, gather real user feedback, metrics. Then gradual evolutions based on concrete data. Minimizes investment risk.

App Development for Businesses

What Kind of Apps We Develop

We specialize in custom app development for B2B and B2C companies that need tailored solutions, not templates. Every project starts from scratch with dedicated UX/UI analysis.

B2B Internal Tool Apps

Apps for employees: order management, inventory tracking, field service, reporting. Integration with company ERP/CRM, SSO authentication, offline sync for areas without coverage.

Customer / Consumer Apps

Apps for your end customers: mobile e-commerce, loyalty programs, bookings, order tracking. Social login, personalized push notifications, in-app payments (Stripe, PayPal).

Mobile Marketplace

Multi-sided platforms: buyer + seller. Listing management, integrated chat, review system, payments with automatic fees, seller dashboard.

Booking & Delivery

Apps for bookings (restaurants, hotels, services) or delivery (food, grocery, courier). Real-time GPS tracking, order status notifications, driver/restaurant ratings.

Field Service & IoT

Apps for external technicians: job dispatch, checklists, digital customer signature, before/after photos. IoT device connection via Bluetooth/NFC.

Content & Community

Content-driven apps: mobile blog, video streaming, podcast, forum. Infinite feed, user-generated content, moderation, engagement analytics.

iOS, Android or Cross-Platform? When Each Makes Sense

The choice of technology stack impacts timelines, costs, and performance. Here is when we recommend each option.

Native iOS Apps (Swift/SwiftUI)

When to choose it: Your primary target is iPhone/iPad, you need maximum performance (gaming, AR, video editing), iOS-specific design (widgets, Face ID).

✓ Excellent performance • ✓ Full access to iOS APIs • ✗ iOS only • ✗ Double cost for Android

Native Android Apps (Kotlin/Jetpack Compose)

When to choose it: Your primary target is Android (e.g. B2B target with company Android devices), integration with specific Android hardware.

✓ Excellent performance • ✓ Full access to Android APIs • ✗ Android only • ✗ Double cost for iOS

Cross-Platform (React Native / Flutter)

When to choose it: Limited budget, you need both iOS and Android, content-based app (not gaming/AR), fast time-to-market. 90% of the code shared.

✓ One codebase = iOS + Android • ✓ Costs -40% vs native • ✓ Synchronized releases • ✗ Slightly lower performance in heavy tasks

Our recommendation: For startups/MVP → Cross-platform (React Native). For consumer apps with millions of users → Native. For standard B2B → Cross-platform works great.

iOS App Development for Businesses

iOS app development in Swift/SwiftUI is the right choice when your target audience is primarily iPhone and iPad, or when you need platform-specific Apple features: widgets, Face ID, Apple Pay, CarPlay, ARKit. Native iOS apps guarantee the best possible performance, full access to Apple APIs, and a user experience perfectly integrated with the operating system.

We develop iOS apps from the discovery and UX design phase all the way to App Store publishing, including managing the Apple review process and ASO optimization for store keywords.

Android App Development for Businesses

Android app development in Kotlin/Jetpack Compose is ideal for B2B targets with company Android devices, for apps with specific hardware integrations (NFC, barcode, peripherals), or when the target market is predominantly Android (e.g. Italy, where Android holds around 65% market share). Native Android apps offer optimal performance and full access to the Google ecosystem.

We handle the entire Android app development lifecycle: architecture, UX/UI, development, testing on real devices, and publishing on the Google Play Store with product listing optimization.

Typical Features (Tech Deliverables)

What does "turnkey" mobile app development concretely include?

✓
UX/UI Design: Wireframes, high-fidelity mockups, design system (colors, fonts, components). Interactive prototype (Figma) before starting development.
✓

Backend, Database and API Integrations

A mobile app without a robust backend is an empty shell. We develop the entire server-side infrastructure.

Typical Backend Stack

• API Server: Node.js (Express/NestJS), Python (Django/FastAPI), or Go
• Database: PostgreSQL (relational), MongoDB (NoSQL), Redis (cache)
• File Storage: AWS S3, Cloudinary for user images/videos
• Authentication: JWT tokens, OAuth2, session management
• Real-time: WebSocket (Socket.io) for chat, live notifications

Common Integrations

• CRM/ERP: Salesforce, HubSpot, SAP, Zoho, Odoo
• Payments: Stripe, PayPal, Braintree, Adyen
• Email/SMS: SendGrid, Mailgun, Twilio
• Analytics: Google Analytics, Mixpanel, Amplitude
• Push Notifications: Firebase, OneSignal, AWS SNS

Working Method: Discovery → Design → Build → QA → Store

Step 1: Discovery (Week 1)

Workshop on business goals, target users, core features, competitor analysis. Deliverable: functional document, user stories, app sitemap.

Step 2: UX/UI Design (Weeks 2-3)

Low-fidelity wireframes, high-fidelity mockups, design system, interactive Figma prototype. Approve the design before starting development.

Step 3: Build (Weeks 4-12, in sprints)

App frontend + backend API development in parallel. Bi-weekly sprints with a working demo on TestFlight/Beta. Continuous feedback, dynamic backlog.

Step 4: QA & Testing (Weeks 12-14)

Functional tests, regression, performance (loading 10,000 items), device testing (iPhone 12,13,14,15, various Android), critical bug fixes. Beta testing with 20-50 real users.

Step 5: Store Publishing (Weeks 15-16)

Store asset preparation (icon, screenshots, description, ASO keywords), App Store + Google Play submission, review process management, public release. Post-launch monitoring.

Timelines and Costs (Main Drivers)

The cost depends on UX complexity, number of screens, API integrations, custom backend, and target platforms.

Factors that affect the quote:

• Number of screens: MVP 10-15 screens vs complex app 50+ screens
• Integrations: How many external APIs? (payments, maps, CRM, analytics, push)
• Offline mode: Do you need local data synchronization? Increases complexity +30%
• Roles and permissions: Admin, standard user, moderator → complex authorization logic
• Real-time features: Chat, live GPS tracking, push notifications → WebSocket backend
• Admin panel: Need a web dashboard to manage the app? +20% costs

Indicative ranges:

• Simple MVP app (cross-platform): 15.000 - 25.000€
• Medium complexity app (native iOS + Android): 30.000 - 50.000€
• Complex app (marketplace, real-time, integrations): 50.000 - 100.000€+

Includes: UX/UI design, app development, backend, QA, store publishing, 3 months support.
