FAQ
Can you turn my idea into an iPhone app?
Yes. Share your idea, even if it's rough, and I'll help define the features, screens, and flow, then build the app step by step. Sketches, references, and similar apps help a lot.
Do you build iOS apps with SwiftUI?
Yes, I build modern iOS interfaces with SwiftUI and Swift. When you also need Android, I use React Native or Flutter so one codebase covers both.
Can you fix my existing iOS app?
Yes. I can fix crashes, bugs, layout problems, and slow performance, and add new features. Message me a short description of the issue before you order.
Can you publish my app to the App Store?
Yes, on the package that includes app submission. I'll prepare the release build and help you submit it under your own Apple Developer account, so you keep full ownership. That account is a paid membership from Apple.
Can you make both Android and iOS apps?
Yes. With Flutter or React Native, I can build one app for both platforms, which usually saves time and cost.
