About

We work at the intersection of strategy, development and delivery

We make cross-platform applications when a business needs a quick launch on iOS and Android

Cross-platform development is suitable when it is important to quickly bring a product to two platforms, maintain a single logic, simplify support, and not have two separate development teams. We design UX, design, backend, API, analytics, push notifications and integrations so that the product works equally confidently on iOS and Android.

First, we determine whether React Native or Flutter is suitable for the task, then we collect architecture, design, development, testing and publishing into a single, understandable plan.

Tasks

A cross-platform application is suitable when you need to launch a product on iOS and Android simultaneously and maintain a single development team.

For what tasks do you need a cross-platform application?

  • Quick launch of MVP on iOS and Android
  • Creating a client service for two platforms
  • Reducing the cost of mobile product support
  • Unified interface and business process logic
  • Integration with CRM, ERP, 1C and internal APIs
  • Connecting payments, push notifications, maps and analytics
  • Replacing legacy native apps
  • Mobile product development without two separate code bases
Let’s discuss your task

On a call or in chat, we’ll unpack the task, answer questions and suggest a solution. If you are only exploring options, write to us too β€” we’ll help you find your bearings.

Leave your contacts β€” we’ll explain the best way to approach the project, how long it may take and what it may cost. No pressure or obligations.

Approach

First, we check whether the cross-platform stack is suitable for the product and business limitations

The approach on which cross-platform development is based

  • Selecting a stack for the task

    We compare React Native, Flutter and native development so as not to use the wrong solution at the start.

  • Designing a unified logic

    We collect scenarios, roles, screen states and backend so that the product develops without discrepancies between platforms.

  • Taking into account the differences between iOS and Android

    We put platform features, permissions, publishing, navigation and UX details where it really matters.

  • We are preparing releases for two platforms

    We configure builds, testing, analytics, crash reports and publication in the App Store, Google Play or RuStore.

Process

Each stage has a clear result and an agreed amount of work

We use a 6-step system,

For each stage we record tasks, deadlines and costs. This way, the application development process remains transparent for you and predictable for the team.

Stage 1

Analysis

Study of the problem and requirements

We analyze the product, audience, business processes, user roles and platform limitations.

Stage 2

Prototype

Structure, logic and product prototype

We design general product logic, roles, navigation, screen states and data exchange with the backend.

Stage 3

Design

Visual concept development

We create an interface for iOS and Android, take into account platform differences and assemble a UI kit for development.

Stage 4

Development

Implementation of project functionality

We write an application in React Native or Flutter, connect the backend, authorization, push notifications and integrations.

Stage 5

Testing

Checking and fixing errors

We test the product on iOS and Android, different devices, OS versions and critical scenarios.

Stage 6

Launch

Publication and commissioning

We are preparing builds, publication in stores, release materials and support for the first users.

Technologies

We select a stack based on launch speed, support and product requirements

We use technologies that are suitable for a single mobile database

  • Mobile: React Native or Flutter, common code base, platform modules and adaptation for iOS and Android.

  • Integrations: CRM, 1C, payments, cards, push notifications, analytics, chats and external services.

    Integrations

    CRM, 1C, payments, cards, push notifications, analytics, chats and external services.

  • Infrastructure: CI/CD, builds for two platforms, test environments, crash reports, monitoring and releases.

Guarantees

We guarantee transparent work and support after launch

  • We pass on instructions, explain how to work with the admin panel, analytics, push notifications, releases and basic support scenarios.

    Team training

  • We record stages, milestones and priorities so that the team understands the development status and the next release date.

    Meeting deadlines

  • We check the interface, API, integrations, stability of assemblies, authorization, payment and data sending scenarios.

    Quality of work

  • We divide the work into understandable stages and show in advance which features are included in the price and which are best included in the next release.

Advantages

We plug into not only development, but the business logic of the project

What will you get by ordering a cross-platform application from us?

  • One product for iOS and Android

    You launch a mobile service on two platforms without two separate teams and disparate logic.

  • Faster first release

    A single code base helps you quickly assemble an MVP, test hypotheses, and reach users.

  • Backend and integrations

    We connect the application with CRM, payment, analytics, internal services, personal accounts and admin panel.

  • Easier development

    New features, analytics, fixes and updates are released simultaneously for iOS and Android.

Cost of a cross-platform application

Guidelines for development formats on a single code base. We calculate the exact price after the brief - we take into account platforms, backend, integrations and deadlines.

How much does it cost to develop a cross-platform application?

  • Cross-platform MVP

    First version for iOS and Android with key scripts and backend

    from 900,000 β‚½from 3 monthsDetails

  • Client application

    Personal account, applications, payment, push notifications, integrations and publishing in stores

    from 1,200,000 β‚½from 3 monthsDetails

  • Mobile platform

    Roles, payments, chats, cards, analytics, complex backend and admin panel

    from 1,600,000 β‚½from 4 monthsDetails

  • Application development

    Audit, improvement, transfer to a new architecture, optimization and new functions

    from 250,000 β‚½from 2 weeksDetails
What determines the final cost?

The price of a cross-platform application depends on platforms, functions, backend and integrations

The cost of a cross-platform application depends on the number of screens, roles, platform features, backend logic, integrations, payments, push notifications, analytics, publishing and support requirements. An MVP on two platforms and a full-fledged mobile platform with a personal account, payment, chats and cards are different amounts of work.

To choose the right stack and name a fair price, we first analyze the problem: we fix scenarios, platform restrictions, integrations, requirements for releases and development. After this, we prepare a commercial proposal with stages, deadlines and clear costs. Brief and calculation - free.

FAQ

We answer the most important questions

When is it better to choose cross-platform development?

When you need to launch a product on iOS and Android simultaneously, it’s faster to test a hypothesis, maintain uniform logic and reduce support costs.

What to choose: React Native or Flutter?

The choice depends on the product, interface, integrations, team and development requirements. We evaluate the task and propose a stack before development starts.

Will the app look good on iOS and Android?

Yes. We account for platform differences in navigation, permissions, states, publishing, and UX details where it matters to users.

Is it possible to connect payments, push notifications, cards and CRM?

Yes. We connect payments, notifications, maps, analytics, CRM, 1C, ERP and other services for specific product scenarios.

Is it possible to switch to native development later?

Yes, if the product grows and there are reasons for native development. At the start, we lay out the architecture so that development is predictable.

What happens after launch?

We monitor metrics, feedback and bugs on both platforms, release updates and help plan the next stage of the product.
