Cross-platform mobile app development in Kyiv and across Ukraine

We create cross-platform mobile products for businesses — from shaping the idea and product strategy to full release in the App Store and Google Play. We work with companies in Kyiv and other cities of Ukraine, developing stable and secure solutions with a single codebase that ensure faster time to market, reduced development and maintenance costs, and a consistent, high-quality user experience on both iOS and Android.

Cross-platform mobile apps portfolio

One app — double customer reach

One product for iOS and Android
The cross-platform approach allows you to create a single mobile product that works simultaneously on iOS and Android. This simplifies development, maintenance, and updates, as logic, business processes, and functionality are centralized in one codebase.
Faster launch without compromising quality
Thanks to a unified architecture and modern frameworks, development takes less time than building two separate native apps. At the same time, users get stable performance, smooth interfaces, and well-designed UX on each platform.
Flexible integrations and APIs
A cross-platform app easily integrates with CRM, ERP, payment services, analytics, marketing tools, and third-party APIs. This enables building a unified digital ecosystem for the business without platform limitations.
Optimization of development and maintenance costs
One development team, unified logic, and shared updates significantly reduce overall costs for creating and maintaining the product. The business invests in functional growth rather than duplicating identical solutions.
Consistent user experience
The app provides a clear and comfortable experience for users regardless of their device. This increases trust in the product, simplifies onboarding, and positively impacts user retention.
Scalability without technical barriers
The cross-platform architecture is designed with future updates in mind: new roles, features, regions, and increased load. The product evolves easily without complete rebuilding or downtime.

Stages of cross-platform app development

Cross-platform mobile app development follows a clear model: from analytics and design to implementation, testing, and publication in the App Store and Google Play. We consider the specifics of both platforms, performance, UX differences, and marketplace requirements.

01

Product analytics and strategy

We start with an in-depth analysis of the business model, target audience, and competitive environment. We define the key product value, usage scenarios, user roles, and scalability requirements. At this stage, a clear vision of the future app and its technical foundation is formed.

Why cross-platform development is a cost-effective solution for companies

A unified mobile channel for customer interaction
A cross-platform mobile app becomes a постоянная touchpoint between the business and users. Customers gain access to services, information, and features at any time, increasing loyalty and simplifying communication.
Consolidation of digital services in one solution
The mobile app consolidates all key company services — from personal accounts and orders to support and analytics. This reduces fragmentation of digital channels and makes the product more convenient for users.
Support for sales and business operations
A cross-platform app automates sales processes, order processing, and customer communication. This shortens the user journey to the target action and increases the efficiency of business processes.
Comfortable user experience
Thoughtful logic, fast performance, and adaptation to different devices ensure ease of use. Users do not need to spend time searching for functions — everything works intuitively and predictably.
Integration into existing IT infrastructure
The app easily connects to internal company systems, external services, APIs, and databases. This allows using the mobile product as a full-fledged element of the business’s digital infrastructure.
Platform for long-term growth
The cross-platform app is designed with future updates, new features, and increased load in mind. The product is not limited to the initial version but becomes the foundation for further scaling.

Cross-platform mobile apps in 2026 have become the standard for businesses that want to enter the market quickly while maintaining control over development and maintenance costs. A single app for iOS and Android, unified logic, and a shared codebase make it possible to launch full-fledged mobile products without duplicate development.

If you plan to order cross-platform mobile app development in Kyiv, Lviv, Kharkiv, Odesa, Dnipro, Zaporizhzhia, Vinnytsia, Poltava, Chernihiv, Cherkasy, Zhytomyr, Sumy, Rivne, Khmelnytskyi, Ternopil, Ivano-Frankivsk, Uzhhorod, Lutsk, Kropyvnytskyi, Mykolaiv, Kherson, or Chernivtsi, it is important to understand what determines the cost, which stages the development includes, and which solutions are optimal in 2026.

What is a cross-platform mobile app

A cross-platform app is a mobile product that runs on both iOS and Android but is developed as a single system. Business logic, integrations, user scenarios, and most of the interface are shared across both platforms.

Unlike two separate native apps, cross-platform development allows you to:

  • launch products faster;
  • reduce initial development costs;
  • simplify maintenance and updates;
  • scale functionality without duplicating work.

In 2026, this approach is chosen not only by startups but also by medium and large businesses.

When cross-platform development is the right choice

The cross-platform format is optimal if:

  • a fast MVP launch is required;
  • you need to reach both iOS and Android users simultaneously;
  • the project is planned for long-term growth rather than a one-time release;
  • integrations with CRM, payment systems, APIs, and analytics are required;
  • business scaling with new roles and scenarios is planned.

In 2026, most services, marketplaces, client portals, logistics, and B2B solutions are launched in a cross-platform format.

What turnkey cross-platform app development includes

Turnkey cross-platform mobile app development is not just programming. It is a full-cycle process where each stage affects quality and final cost.

Analytics and concept development

At the start, business goals, target audience, user roles, and key scenarios are defined. Product logic is formed with scalability in mind, not just the first release.

UX design

UX architecture defines how users move through the app, what actions they take, and where decisions are made. In cross-platform projects, it is crucial to balance unified logic with familiar iOS and Android patterns.

UI design

The interface is created with brand identity, usability, and adaptation to different screen sizes in mind. In 2026, the focus is not on “visual appeal” alone, but on clarity, speed, and predictability for users.

Development and integrations

The client side, server logic, APIs, payment services, push notifications, analytics, authentication systems, and security are implemented. This stage forms the main portion of development cost.

Testing and optimization

The app is tested across devices, bugs are fixed, and performance and stability are optimized. For businesses, this is critical, as post-release issues are more expensive to fix.

Publishing and support

The release is prepared for the App Store and Google Play, moderation is completed, and analytics are configured. After launch, the product is maintained and updated according to business needs.

What affects the cost of a cross-platform app in 2026

Development cost is calculated individually, but key factors remain consistent:

  • number of screens and usage scenarios;
  • roles and access permissions;
  • complexity of business logic;
  • integrations with external services and APIs;
  • payment systems and subscription features;
  • UX/UI level and customization;
  • security and performance requirements.

In 2026, the cost of turnkey cross-platform mobile app development in Kyiv typically starts from several thousand dollars for MVPs and increases with product complexity. The final price is determined after analyzing business goals and requirements.

Why choose turnkey cross-platform development

The turnkey approach means you receive not just a set of screens, but a complete business tool. The team takes responsibility for architecture, stability, scalability, and compliance with platform requirements.

For businesses, this means:

  • a transparent development process;
  • a predictable budget;
  • reduced launch risks;
  • the ability to grow the product for years instead of rebuilding from scratch.
