Questions

Common questions before starting an iOS project.

Native iOS is best when: your app uses heavy camera/AR/AI features, performance is critical (gaming, video processing), or you need deep Apple ecosystem integration (HealthKit, ARKit, WatchOS). React Native and Flutter are better choices when you need both iOS and Android from one codebase and your app doesn't need cutting-edge native APIs. We advise honestly based on your specific requirements.
Yes. We handle the complete App Store submission — provisioning profiles, certificates, App Store Connect setup, screenshots (all required device sizes), app description, privacy manifest, and Review Guidelines compliance review. Our first-submission approval rate is 100%.
Yes. We target the latest iOS (currently iOS 17/18) and support 2 prior major versions (typically iOS 15+). We use SwiftUI for new apps and handle backward compatibility for apps that need to support older devices. We also conduct compatibility testing on real devices — not just Simulator.
A focused iOS MVP takes 8–12 weeks. A full-featured production app takes 14–20 weeks. These timelines include discovery, UI/UX design, development, QA, and App Store submission. We share a week-by-week plan after the discovery session.
