FAQMobile app questions, answered
The questions Orange County businesses ask most before starting a mobile app project with our Irvine team.
How much does it cost to build a mobile app in Orange County?
Mobile app development cost depends on features, platforms, and complexity — a single-platform MVP costs far less than a feature-rich app across iOS and Android. OCImagine scopes every mobile project up front and provides a fixed quote before work begins, so Orange County businesses know the full investment with no surprises.
How long does mobile app development take?
Most mobile apps take roughly 8 to 16 weeks from discovery to launch, depending on features and whether you target one platform or both. OCImagine, based in Irvine, works in agile sprints so you review working builds throughout, and simpler apps ship toward the faster end of that range.
Should I build a native app or a cross-platform app?
Native apps (built in Swift for iOS or Kotlin for Android) deliver the best performance and full access to device features, while cross-platform React Native shares one codebase across both platforms to reduce cost and time. OCImagine helps Orange County businesses choose based on budget, audience, and performance needs.
Does OCImagine build both iOS and Android apps?
Yes. OCImagine builds native iOS apps, native Android apps, and cross-platform React Native apps from a single codebase. Our Irvine-based developers are fluent in Swift, Objective-C, Java, and Kotlin, so we recommend the approach that best fits your audience, timeline, and budget rather than a one-size-fits-all stack.
What is the mobile app development process?
OCImagine’s mobile app process runs through five stages: discovery and requirements, UI/UX design, development, testing and QA, and App Store or Play Store launch with ongoing support. We collaborate with Orange County clients at every phase and deliver in agile sprints so you see working features throughout.
Do I own the source code for my app?
Yes. When OCImagine builds your mobile app, you own the complete source code with no ongoing licensing fees or lock-in. Our Irvine team hands over everything at project completion, and we offer post-launch maintenance and updates on your terms if you want continued support.
