How much does a custom mobile app for a company cost?
A mobile app MVP usually starts from PLN 12,000 net. The price depends on the number of screens, offline mode, integrations with company systems, the admin panel, and security requirements.
Custom mobile apps for companies: iOS, Android, cross-platform
I build dedicated mobile apps for field employees, service teams, sales, and customers. With an admin panel, offline mode, and integrations with CRM, ERP, or inventory.
A mobile app MVP usually starts from PLN 12,000 net, with the first version in the stores in 3-8 weeks. Direct cooperation with a Krakow-based developer, remote across Poland and the EU.
Service definition
What this service covers
Custom mobile apps for companies are dedicated iOS and Android applications (native or cross-platform) that support field employees, customer service, sales, service operations, and bookings, with an admin panel and integrations with company systems.
Problems I solve
- - Field employees work on phone calls, notes, and photos sent via WhatsApp, and data reaches the system late.
- - Customers want to order, book, or check status from their phone, and the mobile website does not support it.
- - Off-the-shelf apps do not fit the company process or do not integrate with CRM, ERP, and inventory.
What you receive
- - Process analysis and screen mockups
- - iOS and Android app (React Native / native)
- - Backend, admin panel, and API integrations
- - App Store and Google Play publishing and maintenance
For whom
field service companies, logistics and transport, B2B sales, booking-based services, manufacturing.
Typical budget
A mobile app MVP usually starts from PLN 12,000 net; larger apps with panels and integrations are estimated in stages.
Timeline
Usually 3-8 weeks for the first version in the stores.
How I prove value
I design mobile apps around the real process: offline mode, photos, signatures, geolocation, push notifications, and sync with company systems.
FAQ
Native or cross-platform (React Native, Flutter)?
For most business apps, cross-platform (React Native) gives one codebase for iOS and Android at a lower cost. I choose native when very specific hardware features or maximum performance are required.
Can the app work offline and integrate with our system?
Yes. I design offline mode with synchronization and API integrations with CRM, ERP, inventory, calendars, and payments.
Do you handle App Store and Google Play publishing?
Yes. I prepare developer accounts, store assets, builds, review, and post-launch updates.
Who custom mobile apps are for
A business mobile app makes sense when people work away from a desk or customers want to handle things from their phone. The most common use cases:
Field employees
Jobs, checklists, photos, customer signatures, geolocation, and offline mode. Data reaches the system immediately, not after returning to the office.
Service and tickets
An app for technicians and customers: service requests, equipment history, parts, visit schedules, and status notifications.
B2B sales reps
Catalog, price lists, placing orders at the customer's site, stock visibility, and meeting notes synced with CRM.
Customer app
Bookings, orders, order status, payments, loyalty programs, and push notifications instead of calls to the office.
Logistics and transport
Routes, delivery confirmations, barcode scanning, transport documents, and driver-dispatcher communication in one place.
Manufacturing and warehouse
Operation logging, quality control with photos, scanner-based inventory, and reporting breakdowns from the shop floor.
Native, cross-platform, or PWA?
The technology choice drives cost, timeline, and maintenance. I recommend the option that fits the process and budget, not the other way around.
Cross-platform (React Native)
- - One codebase for iOS and Android
- - Lower cost and faster delivery
- - Sufficient for most business apps
- - Easier maintenance and growth
Native (Swift / Kotlin)
- - Maximum performance and hardware access
- - Best for unusual features (AR, BLE, sensors)
- - Two codebases = higher cost
- - Justified for consumer products
PWA / web app
- - No app store publishing
- - Lowest entry cost
- - Limited notifications and offline mode
- - Good as a stage before a full app
How mobile app development works
Process analysis
We define who uses the app and when, what data it collects, and what it must integrate with.
Mockups and prototype
Clickable screens to discuss with the team. After a clear brief, I prepare the first prototype for free.
MVP delivery
Backend, iOS/Android app, admin panel, and integrations. First version in 3-8 weeks.
Publishing and growth
Developer accounts, App Store and Google Play, monitoring, updates, and new features in stages.
Need a web app or admin panel too?
A mobile app rarely works alone. It usually comes with an admin panel, a web app for the office, or an integration with an existing system. See how I combine web and mobile applications into one coherent system.
Describe the process and get an app prototype
Tell me who will use the app, what it should do, and what it must connect to. After a clear brief, I come back within 2-5 days with a clickable prototype and an indicative estimate.
