Mobile Development Services Powered by AI

Build an App from Scratch

Develop native iOS, Android, or cross-platform applications with AI supporting requirements analysis, implementation planning, UI development, and testing. Our engineers define the technical approach and review the implementation throughout development.

Extend Your Existing App

Add screens, user flows, and integrations to your application. We use AI to explore the codebase and follow existing patterns, while engineers check business logic, platform behavior, and compatibility with surrounding features.

Migrate Your Mobile App

Move functionality into a new mobile architecture with AI supporting code analysis, migration planning, and implementation. Our experience includes native-to-Compose Multiplatform and KMP-to-CMP migrations, including platform-specific code and dependency challenges.

Debug and Refine Your Code

Investigate bugs, build failures, and integration issues with AI-assisted analysis of code, logs, and configurations. Engineers review proposed fixes, remove unnecessary complexity, and test whether changes address the original problem.

Develop Tests and Documentation

Expand unit and ViewModel tests, document functionality, and prepare implementation or handover notes. AI supports initial drafts, while engineers check test assertions, error scenarios, and technical accuracy against project requirements.

We'll Recommend the Best Migration Technology

Kotlin Multiplatform (KMP)

Ideal when you need to stay within budget while keeping native UI flexibility.

KMP allows you to share business logic across iOS and Android while still using native UI components,speeding up development without sacrificing performance.

Compose Multiplatform (CMP)

Perfect for teams that want a modern, shared UI and business logic in one codebase.

CMP enables you to build beautiful, responsive interfaces for both iOS and Android, reducing maintenance and accelerating releases.

If not knowing what to choose, here you can get more info about KMP vs CMP.

Flutter

Best for apps requiring a fully shared UI across iOS and Android, ensuring fast cross-platform development with near-native performance and a rich widget library.

React Native

A solid choice for projects that need quick time-to-market and strong community support,offering
a balanced mix of speed, performance, and reusable components.
