Native vs Cross-Platform

We help you choose the right approach based on your budget, timeline, and performance needs.

Native Development

Platform-specific code for maximum performance and access to all device features.

iOS — Swift / SwiftUI
Android — Kotlin / Jetpack Compose
  • Best possible performance
  • Full access to device APIs
  • Platform-native UX patterns
  • Best for GPU-heavy or real-time apps

Cross-Platform

Single codebase for both platforms with near-native performance.

React Native — JavaScript / TypeScript
Flutter — Dart
  • One codebase, two platforms
  • Faster time to market
  • Lower development cost
  • Best for most app types
iOS Development

Crafted for Apple

We build iOS apps that follow Apple's Human Interface Guidelines, leveraging the full power of the Apple ecosystem including HealthKit, CoreML, ARKit, and Apple Pay.

  • Swift & SwiftUI
  • Core Data & CloudKit

FAQ

Frequently Asked Questions

How long does it take to build a mobile app?

A simple MVP takes 6-10 weeks. A full-featured app typically takes 3-5 months. We provide a detailed timeline during the strategy phase.

Should I choose native or cross-platform?

For most apps, cross-platform (React Native or Flutter) is the best choice — faster to build, lower cost, near-native performance. Choose native only if you need heavy GPU processing, AR/VR, or platform-specific features.

Do you handle App Store submission?

Yes. We handle the entire submission process for both Apple App Store and Google Play Store, including screenshots, descriptions, and compliance requirements.

What about ongoing maintenance?

We offer monthly maintenance plans that include OS updates, bug fixes, performance monitoring, and feature additions. Most clients choose our retainer for continuous support.

Can you work with our existing backend?

Absolutely. We integrate with any REST API, GraphQL, or custom backend. We can also help modernize or extend your existing backend if needed.

How do you test across different devices?

We use a combination of physical devices, cloud device farms (BrowserStack, AWS Device Farm), and automated testing to ensure your app works across screen sizes, OS versions, and hardware configurations.
