What we build

Mobile app development — every platform

From native performance to fast cross-platform builds. We pick the approach that fits your project's business goals.

iOS app development
Native iOS in Swift / SwiftUI. App Store-ready builds, TestFlight beta, push notifications, In-App Purchase, Apple Sign In, ARKit when needed.
Android app development
Native Android in Kotlin / Jetpack Compose. Google Play Console, Material You, Firebase, biometric auth, foreground services.
Cross-platform (React Native, Flutter)
One codebase — iOS and Android together. 30–50% faster delivery with near-native performance. We pick the right one with you.
PWA — installable web app
No app store: Progressive Web App, installable icon, offline mode, push notifications. Faster and cheaper than native.
Backend and API
Full backend behind the app: Node.js / Bun / Hono, PostgreSQL, Redis, Cloudflare Workers or AWS. Auth, payments, push, analytics — all from one team.
App Store & Play Store release
Apple Developer setup, Play Console, app review, store listing optimization (ASO), screenshots — we walk you through the release.
Native vs cross-platform

Which one fits your project?

For most B2B and consumer apps we recommend cross-platform — current tooling delivers a 95% native feel. There are still cases where native is the right call.

Native (Swift / Kotlin)

When performance or platform integration is critical

  • · 3D, AR, on-device camera image processing
  • · HealthKit, ARKit, custom widgets, lock screen
  • · Apple Watch / Wear OS companion apps
  • · Maximum native feel and OS-specific patterns
Cross-platform (RN / Flutter)

When you want faster time-to-market and one codebase

  • · iOS + Android together, 30–50% shorter build time
  • · Business apps, MVPs, consumer B2C apps
  • · One team to maintain, not two parallel codebases
  • · Extensible with native modules where needed
Process

How a mobile app project actually runs

MVP in 2–3 months for a single platform, 3–4 months for cross-platform. Live build every sprint, you watch progress unfold.

1. Discovery — feature list, platform, technology

We align on the ICP, the main user flows, the monetization model (subscription, in-app purchase, freemium), and decide: iOS-only, Android-only, or cross-platform. By the end you have a one-page brief and a fixed-price MVP package.

2. UX/UI design — Figma + interactive prototype

User flows, wireframes, visual design in iOS and Android variants. An interactive Figma prototype that you can test with stakeholders before a single line of code is written.

3. Build — sprints + TestFlight / Play beta

Two-week sprints with TestFlight (iOS) and Play Console internal track (Android) builds. Continuous beta testing with stakeholders. Backend API and frontend run in parallel.

4. App Store + Play Store release

App Store review, Play Console release. ASO (store listing optimization), screenshots, descriptions, categories. If something gets rejected, we handle the appeal.
