Mobile app development for businesses (also known as enterprise mobile application development, B2B mobile app development or enterprise mobile development) is a service in which an expert team designs, builds and operates business-grade iOS and Android applications in an enterprise environment. A mobile app can be native (Swift / Kotlin) or cross-platform (React Native / Flutter), and typically breaks down into 3 phases: MVP (6–12 weeks), production release (12–26 weeks), and continuous iteration (in monthly to quarterly cycles). Unlike classic software development, mobile app development requires specific platform compatibility, App Store / Google Play compliance and performance optimization.
AP4 Digital’s Budapest-based team builds B2B mobile apps for iOS and Android: MVP in 6–12 weeks at a fixed fee, using native (Swift, Kotlin) or cross-platform (React Native, Flutter) technology, with 50+ delivered mobile apps as references.

Native vs cross-platform decision matrixMVP feature scope: what to leave outRealistic budget ranges for 6 mobile app tiersAuthor: István Dienes · Managing Director, AP4 Digital · Technical review: the AP4 senior mobile development team
A well-designed mobile app pays off when it strengthens the customer relationship or speeds up daily work. With bookings, orders, payments, status tracking, field data capture or push notifications, it is no longer just a digital surface, it becomes a tool that delivers business advantage.
Bookings, loyalty programs, push, quick reordering, here an app drives retention and revenue.

If you only need a brochure site, returning customers are rare, there is no booking or login, and the budget is limited: a responsive website or PWA is the better choice.
We'll tell you honestly on the 30-minute call, if the app won't pay off, we won't recommend it.
30-minute consultationOne of the most important decisions in mobile app development is not the design, it is the platform. A premium customer app, a quickly validated MVP and an internal enterprise system each call for a different solution. Features (AI assistant, offline, push, payments) are not separate technologies: they layer onto any platform.
After the platform decision, we layer the features on according to the needs of the project.
We choose native development when a platform-specific experience, performance or device integration is the priority.
When the platform is the product experience
A cross-platform solution may be more economical when functionality is largely the same on both platforms and the long-term benefit of a shared codebase outweighs the platform compromises.
When the shared codebase is worth more
The project decides, not a technology preference: scope, device capabilities, performance requirements and long-term operation together determine which route is more economical.
AI can assist with preparing shared and platform-specific code, extending test cases, debugging, API integration and release documentation.
Acceleration does not replace verification on real devices, with integrations and actual user flows.
These decisions are made by a named professional, not by the model.
transport, hospitality, healthcare, logistics, B2B mobile products have been brought into live operation. Each case study identifies AP4's role and which outcomes are public.
Within 2 business days of a 30-minute call we send a preliminary scope with time and budget ranges: the detailed proposal follows after discovery.
We start the first conversation with the business context and recommend an app only when it is genuinely justified.

Enterprise mobile development has four typical routes, and each has its place - for different situations. The criteria below help you choose for your own project; the table describes category traits, it does not rate specific vendors.
From discovery to production iteration, one closed loop, six stations. Refined through 50+ delivered B2B mobile apps.
We rewrote an industrial client's native Kotlin Android application onto an agent-based React Native stack in 50 days: the original native codebase shrank by half, and test coverage grew from 12% to 78%.
The native Kotlin version was a codebase twice the size, the result of three years of iteration. With the agent-based rewrite, redundant layers fell away, the architecture was cleaned up, and the test pyramid was rebuilt. SonarCloud metrics are A-grade in both versions, but the nature of the issues differs substantially: duplicated business logic and hard-coded configuration were typical in the old code; in the new version these exist as centralized modules.
A 4–8 person senior-led boutique studio, since 2013 · 50+ delivered mobile apps · 13+ industries.
Your corporate data stays in your own tenant. Zero data retention, EU data residency, dedicated key pair. Self-hosted LLM is also an option.
Across 13+ industries: tourism, healthcare, transit, automotive, hospitality, education. We won't be learning on your project.
First working PoC in 2–6 weeks, production app in 12–26 weeks. Seniors + AI agents in parallel, one person ships as much per sprint as a classic 4-person team.
You don't need to understand the stack, we explain what each development type is for and in which business situation it pays off fastest.
When to use which? We decide during the 30-minute call: premium UX → native; fast MVP → React Native; AI features → alongside any stack with a native SDK.
TMRW Hotels - digital guest experience and mobile product. BKK Telebusz - an app supporting a travel and service process.
Every case study states the starting situation, the solution delivered, the type of result and - where publishable - how it was measured. If a result is not public, we say so.
