FAQ
Questions We Hear Every Week
iOS app development is building native apps for iPhone and iPad, usually in Swift and SwiftUI, and publishing them on Apple's App Store. It covers the interface, device features such as Face ID and Apple Pay, the backend the app talks to, and the yearly updates each new iOS release requires.
A focused iOS MVP with one core user flow costs $15,000 to $40,000. A full app with accounts, payments, an admin panel and integrations runs $40,000 to $100,000, and complex or regulated apps start around $100,000. Cost follows screen count, integrations and the depth of QA. You get a fixed-price quote after a free scoping call.
A focused MVP takes 8 to 12 weeks from kickoff to App Store submission. A full app with payments, an admin panel and integrations takes 3 to 6 months. Apple usually reviews a build within 24 to 48 hours, and you see a working TestFlight build every two weeks.
Yes. We build native iOS apps in Swift, using SwiftUI for modern interfaces and UIKit where it makes sense. You get a fast app that feels right at home on Apple devices.
Yes. We manage the full release: store listing, assets, review guidelines, submission and post-launch fixes, so your app goes live smoothly.
Yes. Every build ships with a support window, and we offer maintenance plans covering monitoring, OS updates, crash fixes and new features.
Absolutely. You own 100% of the source code, design files and intellectual property. We can also sign an NDA before any discovery conversation.
Start where your users are. iPhone leads in the US, UK, Australia and among higher-spending customers; Android leads in India, Africa and much of Asia. If you need both from day one, a Flutter or React Native build covers both stores from one codebase.
Apple reviews most submissions within 24 to 48 hours. A rejection adds a fix-and-resubmit cycle, usually for privacy labels, login requirements or in-app purchase rules, so we check every build against Apple's review guidelines before it is submitted.
Plan for roughly 15 to 20 percent of the original build cost per year. That covers the annual iOS release, new device sizes, SDK and privacy-policy changes, security patches, crash fixes and hosting. New features are scoped separately as fixed-price releases or under a retainer.
