My service already runs on Base44, but the mobile experience still feels like a squeezed-down website. I need a true native build for both iOS and Android that keeps everything users love and presents it in a smooth, store-ready interface. Here’s what absolutely has to make the jump from web to mobile: • User login and authentication • Push notifications • In-app purchases The current codebase is clean enough to reuse most of the business logic, yet the UI needs a full redesign to follow Apple HIG and Material guidelines. I’m happy to supply existing APIs, artwork, and test credentials; you’ll focus on Swift/SwiftUI (or Objective-C if you insist) for iOS and Kotlin for Android, wiring each screen, refining the flows, and making sure both apps pass App Store and Play Store review. Deliverables include well-commented Xcode and Android Studio projects, signed release builds, and a brief hand-off session that walks me through publishing and future updates. If you’ve shipped native apps with secure logins, real-time notifications, and purchase flows before, I’d love to see your approach and timeline.

Your Base44 service deserves a mobile experience that feels native not a responsive web view dressed up as an app. You've identified the gap correctly, and the fix is a proper Swift/SwiftUI + Kotlin build, not another wrapper. You've made this straightforward: existing APIs ready, artwork supplied, business logic reusable. This is pure execution UI redesign and native implementation, no discovery phase needed. Swift/SwiftUI for iOS following Apple HIG throughout. Kotlin for Android built to Material guidelines. Both platforms wired to your existing APIs, auth flows implemented natively, push notifications integrated properly for each platform, and in-app purchases handled correctly App Store and Play Store each have distinct IAP review requirements that we know well. UI redesigned for each platform's conventions not a pixel copy between iOS and Android, but a cohesive experience that feels at home on both. Well commented Xcode and Android Studio projects, signed release builds, and a handoff session walking you through publishing and future update workflows included as standard. Plan D Studios 12+ years building native mobile apps, iOS and Android development, and store submission workflows. All in house. One question: does your Base44 service use REST APIs or does it have a custom SDK we need to integrate against? Let's get both stores covered. Message us. Regards, Haider

Hi there To turn your Base44 service into true mobile apps, the most critical part is redesigning the experience so it feels native—not just a “squeezed-down website.” I’ll approach this by rebuilding the UI in SwiftUI (iOS) and Kotlin (Android), while reusing your existing APIs to keep business logic consistent. This means I understand how to translate web flows into smooth mobile interactions, implement secure authentication, and integrate push notifications and in-app purchases in a store-compliant way. My process is simple: Redesign UX based on Apple HIG and Material guidelines Build native apps connected to your existing backend Implement push notifications, IAP, and finalize store readiness I’m ready to begin with UX mapping and a core screen prototype, then iterate into full production apps. If this aligns, we can discuss in detail in chat..

Hi, I will build native iOS (SwiftUI) and Android (Kotlin) apps from your Base44 service, redesigning the UI to follow Apple HIG and Material guidelines. Authentication, push notifications, and in-app purchases will all carry over into a smooth, store-ready experience on both platforms. I will structure the networking layer to share the same API contracts your Base44 site already uses, so both apps stay in sync with the web version without duplicating backend logic or requiring new endpoints. Questions: 1) Are your existing APIs documented, or will I need to map them from the Base44 codebase? 2) For in-app purchases, are these subscriptions, one-time unlocks, or consumables? 3) Do you have design assets (icons, brand guidelines) ready, or do you need UI/UX design as well? Looking forward to discussing further. Best regards, Kamran

Hello, I understand you want to turn your Base44 web service into true native mobile apps for iOS and Android, improving the user experience by redesigning the UI from scratch while keeping core features intact. I will focus on Swift/SwiftUI for iOS, following Apple’s design rules, and Kotlin for Android, following Material guidelines. I plan to reuse your current business logic wherever possible to speed up development. Key features, user login, push notifications, and in-app purchases, will be implemented securely and smoothly, ensuring your apps meet all App Store and Play Store requirements. I’ll deliver well-documented code, signed builds, and a clear walkthrough for publishing and updates. To get started, I’d like to clarify a few things:Are there any specific edge cases or special flows in user login, notifications, or purchases that I should be aware of? Do you want the apps to support offline usage or caching for better performance? What existing APIs do you already have for push notifications and in-app purchases? Have you planned any user analytics or crash reporting tools to be integrated? Is there a target timeframe or launch date for publishing both apps? Thanks,

I build native Android apps in Kotlin and have recently worked on iOS as well so I can cover both sides of this. For Android I will wire up auth, push notifications via FCM and in-app purchases through Play Billing, all following Material guidelines. For iOS the same flows in SwiftUI with APNs and StoreKit. Both apps will consume your existing APIs so the business logic stays intact, only the UI gets a proper native treatment. I will deliver commented Xcode and Android Studio projects, signed builds ready for both stores and walk you through publishing at handoff. A couple of things before I put together a timeline: What does your current auth look like, token based or session based? Are the in-app purchases one time or subscriptions? Looking forward to hearing back from you soon. Thanks!
