We build native and cross-platform mobile products — from MVP and UX/UI design to backend, integrations, launch, and ongoing support.
Promodex builds mobile apps for iOS and Android: native apps in Swift and Kotlin, cross-platform products in Flutter, React Native, and .NET MAUI, MVPs, ecommerce apps, enterprise services, and PWAs.
We cover the full cycle — discovery, UX/UI design, mobile development, backend, APIs, integrations, testing, release preparation, and ongoing product growth. We choose the technology based on features, budget, timeline, and scaling plans.
We bring market research, digital marketing, web development, CRM, analytics and technical support together into one seamless workflow.
Trusted by clients across the US, Europe and Ukraine
Mobile app development means building a digital product that helps a business work with customers, employees, or partners through smartphones and tablets. A mobile app can be a standalone sales channel, a booking or delivery service, a customer portal, a loyalty program, an internal company tool, or part of a larger digital ecosystem. At Promodex, we don't start by picking a technology — we start with the business logic, target audience, required integrations, and use cases. Only then do we decide whether the product calls for native iOS or Android development, a cross-platform approach, an MVP, or a PWA.
A native approach makes sense when a product has demanding performance requirements, relies heavily on device capabilities, or needs to feel fully at home on its platform. We build iOS apps in Swift and Android apps in Kotlin. This lets us fine-tune interface behavior, system features, push notifications, geolocation, the camera, biometrics, background processes, and other capabilities specific to each operating system. Native development usually means separate work for each platform, so it's the right choice where gains in performance, device integration, or platform-specific UX justify the extra development effort.
Cross-platform mobile app development fits projects that need to launch on iOS and Android at the same time and keep most of the logic in a single codebase. We work with Flutter, React Native, and .NET MAUI, choosing the tool based on the product architecture, your current tech stack, UI requirements, and long-term maintenance. Flutter is a strong fit for products with a custom UI system and a unified visual language. React Native makes sense for teams and products already invested in the React ecosystem. .NET MAUI can be a practical choice for projects tied to .NET and Microsoft enterprise infrastructure.
Going cross-platform doesn't eliminate platform-specific work. Certain integrations, system permissions, interface behavior, and publishing still need to be verified separately for iOS and Android. Our job is to identify where shared code genuinely cuts costs and where a native module or separate implementation is the better call.
A mobile app MVP lets you validate a business hypothesis without building the full planned feature set up front. We define the product's core value, the critical user flows, and the minimum set of features needed to launch. That might be sign-up, a user profile, a catalog, ordering, booking, payments, chat, push notifications, or another core process. After launch, we collect data and feedback so your next investments go into features that prove their value to users.
For ecommerce, a mobile app can become a dedicated channel for repeat sales and customer retention. We build catalogs, search, filters, wishlists, shopping carts, payments, shipping, order history, rewards programs, and push messaging. The app can run on the same CRM, ERP, catalog, and inventory system as your website. For service companies, we build mobile customer portals, booking, requests, documents, status tracking, subscriptions, and notifications. For internal operations, we create tools for employees, field teams, managers, and partners.
Mobile app design starts with user scenarios, not with styling individual screens. We design the information architecture, user flows, prototypes, and interface states, then build a UI system for iOS, Android, or a cross-platform product. We account for navigation patterns, screen sizes, native platform conventions, accessibility, and how users interact with the keyboard, gestures, and notifications. For larger products, we create a design system and component library so new features can be added without visual fragmentation.
A mobile app is often just the client side of a larger system. User data, orders, payments, subscriptions, content, and business rules are handled on the backend. Promodex designs APIs and implements authentication, user roles, push logic, data sync, and third-party service connections. We integrate mobile products with CRMs, ERPs, payment gateways, shipping providers, maps, analytics, telephony, and other APIs. If you already have a website or server-side system, we first assess whether the existing infrastructure can be reused to avoid duplicating business logic.
Launch isn't the finish line. Operating systems, SDKs, libraries, and app store requirements keep changing, and users develop new habits and expectations. Our mobile app support covers bug fixes, dependency updates, adapting the product to new platform versions, building out new features, and monitoring key integrations. We also analyze crash reports, events, and user behavior to plan technical and product improvements based on data.
A PWA can be an alternative to a standalone mobile app when a business needs a fast mobile experience without full native development. A Progressive Web App runs in the browser, can be installed on a device, and can use some app-like capabilities. This format works well for catalogs, customer portals, online services, and ecommerce projects where a quick launch and a single web codebase matter. That said, access to system features and PWA behavior can differ from native apps, so we evaluate this option against your specific requirements.
Promodex combines mobile development with backend, web, UI/UX, analytics, and digital marketing. That means we build your app not as an isolated product but as part of a unified digital system for your business. Our team can design the mobile interface, server logic, API, integrations, and analytics — and then support and grow the product after launch. We don't default to native or cross-platform: the technology is chosen after evaluating features, budget, timeline, performance requirements, and growth plans.
