Mobile App Development for iOS & Android

Both. We build native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose) apps for performance-critical use cases. For most business apps, we use React Native or Flutter, which deliver near-native performance at significantly lower cost and development time.

Mobile app projects at Zenkoders typically range from $30,000 for a focused MVP to $150,000+ for a complex app with custom AI features, complex backend, and both iOS/Android. We provide fixed-price quotes after a detailed scoping session.

Yes. We handle the full submission process including App Store Connect and Google Play Console setup, screenshots, descriptions, review submission, and responding to reviewer feedback. First-time apps typically take 1–3 days for approval.

Absolutely. AI is now standard in our mobile app stack. We integrate on-device AI (Apple Core ML, Google ML Kit) for offline features, and cloud AI (OpenAI, Claude) for more complex capabilities like conversational interfaces, image analysis, and personalization.

Yes. We offer monthly maintenance retainers covering OS update compatibility, bug fixes, performance monitoring, and minor feature additions. Most clients use a retainer of $1,500–$5,000/month depending on app complexity.

A focused mobile MVP takes 8–12 weeks. A full-featured consumer or B2B app takes 16–24 weeks. Apps with complex real-time features (video, maps, IoT) take longer. Timeline depends heavily on backend complexity.
