Native Swift & SwiftUI
Modern iOS development with Swift and SwiftUI. Clean architecture, async/await concurrency, and Human Interface Guidelines — apps that feel at home on Apple hardware.
Apple Ecosystem Integration
ARKit, Core ML, HealthKit, Sign in with Apple, Apple Pay, Face ID — we integrate the full Apple platform API surface, not just the basics.
iPhone, iPad & Beyond
Universal apps with adaptive layouts for every screen size, plus watchOS, tvOS, and Mac Catalyst. One codebase built to scale across the Apple ecosystem.

iOS Development FAQ
How long does iOS app development take?
A native iOS MVP covering core features typically takes 8–12 weeks from design kickoff to App Store submission. A more complex iPhone or iPad app with custom integrations, real-time data, and payment flows takes 14–20 weeks. We work in two-week sprints so you see a working build throughout development, not just at the end.
Do you build for iPhone only or iPad too?
We build for iPhone, iPad (universal apps with adaptive layouts), and the full Apple ecosystem including Apple Watch (watchOS), Apple TV (tvOS), and Mac (macOS via Mac Catalyst or native SwiftUI). Most of our clients start with iPhone and we expand to iPad and other platforms in later phases.
What iOS technologies does Ortem use?
We build with Swift as the primary language and SwiftUI for modern declarative UI, with UIKit for components that require it. Architecture-wise we follow MVVM or TCA depending on project complexity. For networking we use URLSession/Combine or Swift Concurrency, for persistence SwiftData/Core Data, and for backend connectivity REST APIs, GraphQL, WebSockets, and Firebase.
Should I build native iOS or use Flutter/React Native?
Native iOS (Swift/SwiftUI) gives you the best performance on Apple hardware, full access to the latest iOS APIs (ARKit, Core ML, HealthKit, Vision), and the tightest integration with the Apple ecosystem. If you need iOS and Android simultaneously on a tighter budget, Flutter or React Native are strong alternatives. We build all three and help you choose based on your product requirements.
Need Android Too?
If you need iOS and Android simultaneously, Flutter lets us share 90%+ of the codebase without sacrificing quality. We also build native Android separately. We'll help you choose the right approach for your timeline and budget.
