Mobile App Development for iOS & Android
We design and build native and cross-platform apps — from prototype to App Store and Google Play with real business results.
About mobile app development
A mobile app is not a stripped-down website. It is a standalone product with native UX, offline capability, and a direct channel to users through push notifications.
- iOS + Android
- React Native / Flutter / Native
- Full App Store & Play Store submission
When a mobile app is the right move
A mobile app gives direct access to users via push notifications, works offline, and delivers native UX unavailable in a browser. If your audience relies on smartphones for core tasks, a mobile app pays off quickly.
What your business gets

What you get at launch
Not just an app in the store — a complete kit for launch and growth.
Figma design files
All screens, design system, components and icons — handed over with full rights.
Source code in Git
Clean code with README, API documentation and a local-setup guide.
Analytics and crash reports
Firebase / Amplitude wired up with a dashboard for key product metrics.
Push notifications
A configured messaging service with audience segmentation and campaign templates.
Warranty and support
1 month of free post-launch fixes plus an optional SLA for ongoing development.
How we work
Transparent process from idea to App Store and Google Play.
-
Brief and research
We analyze goals, audience, competitors, and success metrics. We define the stack and MVP scope.
-
UX design
User flows, wireframes, and a clickable prototype — all done before development starts.
-
UI design
All screens designed in Figma following Human Interface Guidelines and Material Design.
-
Development
2-week sprints with a demo at the end of each. Code ships with tests, docs, and CI/CD.
-
QA and testing
Manual and automated testing on real devices. Crash-free rate > 99.5%.
-
Launch and growth
We submit to App Store and Google Play. We configure analytics, pushes, and A/B tests.
App case studies
Real projects across different industries — from e-commerce to service businesses.

Technologies and stacks
We pick the stack for the task, not for the trend.
Cross-platform
- React Native
- Flutter
- Expo
Native
- Swift / SwiftUI
- Kotlin / Jetpack Compose
Backend & API
- Node.js
- PHP / Laravel
- PostgreSQL
- Firebase
Infrastructure
- AWS / GCP
- CI/CD
- TestFlight
- Google Play Console
Native vs cross-platform
React Native / Flutter — one codebase for iOS and Android. Faster to build, more cost-efficient, ideal for most products.
Native (Swift, Kotlin) — maximum performance and full platform API access. We choose this for demanding tasks: AR, background processes, and heavy graphics.
What is included in development
- Discovery and brief — goals, audience, competitors, metrics;
- UX / prototype — flows, wireframes, user journey;
- UI design — all screens in Figma with a design system;
- Sprint-based development — demo every 2 weeks;
- QA on real devices — iOS and Android across generations;
- App Store and Google Play submission — metadata and screenshots ready;
- Analytics and pushes — Firebase, Amplitude, or MixPanel.
Frequently asked questions
How much does a mobile app cost? A single-platform MVP starts from 180,000 UAH. Final cost depends on platforms, UX complexity, integrations, and backend.
How long does development take? An MVP typically takes 2–4 months from kickoff to store publication. A full product with two platforms and a custom backend — longer.
Do you help with App Store submission? Yes. We manage the entire submission process and prepare screenshots and metadata for both stores.

Frequently asked questions about mobile apps
Platforms, budget, timelines, store submission, and ongoing support — what you need to know before kicking off.
01. Native or cross-platform (React Native / Flutter)?
For most products, cross-platform wins on cost: one team, one codebase, faster time to market, cheaper to maintain. Native (Swift, Kotlin) is the right choice when you need maximum performance, AR/VR, heavy graphics, or deep platform API access.
02. How much does mobile app development cost and what drives the price?
A single-platform MVP starts from 180,000 UAH. A full product across two platforms with backend, account area, and integrations — from 350,000–800,000 UAH. The price depends on UX complexity, screen count, server side, integrations (payments, maps, push, analytics), and the number of design iterations.
03. How long does an MVP take?
An MVP with core functionality — 2–4 months from kickoff to store publication. This includes discovery, prototype, UI design, development, QA on real devices, and submission prep.
04. Do you help with App Store and Google Play submission?
Yes. We register developer accounts (or use yours), prepare screenshots, descriptions, icons, privacy policy, go through Apple and Google review, and address any feedback. Accounts stay with you.
05. Can the app integrate with an existing website or CRM?
Yes. We set up unified authentication and a shared backend, sync orders and users with your CRM (Bitrix24, AmoCRM, custom). If your website doesn't have an API yet, we build one.
06. What about post-launch support and updates?
At minimum — updates for new iOS and Android versions so the app isn't pulled from the stores. With a support package — crash monitoring (Firebase Crashlytics/Sentry), bug fixes, feature development, and regular releases.
07. Who owns the code and developer accounts?
All rights to the code, design source files, and content are transferred to you per contract. Apple Developer and Google Play accounts are registered to your company or sole proprietorship — you remain the full owner of the app.
08. Do you handle UX/UI design or only development?
Full cycle: user research, prototypes, UI design with a Figma design system, development, QA, store submission, and ongoing growth. We can also join at any stage — for example, build the app from designs you already have.
