I built my application with Base44, but that platform can’t give me the native hooks needed for Apple’s in-app subscriptions. I now need a clean iOS wrapper that will pass App Store review and let users purchase and manage subscriptions without leaving the app. You’ll take my existing Base44 codebase (already fully tested on the web) and: • Create a native iOS container that meets all App Store requirements. • Add Apple in-app purchases and the full subscription management flow (purchase, restore, cancel, renew). • Handle receipt validation and any server callbacks my backend needs. • Return a signed .ipa ready for TestFlight plus clear setup notes so I can resubmit future builds myself. Everything must comply with Apple’s latest StoreKit guidelines; If anything in my web interface conflicts with Apple’s rules, flag it early so we can adjust before submission. Once the wrapper is approved in TestFlight and subscriptions run end-to-end on real devices, the job is done.

I've worked on several Base44-to-native wrapper projects and know exactly where the platform falls short—specifically its inability to hook into StoreKit for native subscription flows. My approach: I'll build a lightweight Swift/UIKit container using WKWebView to load your existing web app, then integrate StoreKit 2 for the full subscription lifecycle—purchase, restore, renewal, and cancellation—communicating between the native layer and your web interface via a JavaScript bridge. I'll handle server-side receipt validation against Apple's App Store Server API and flag any web UI elements (like external payment links) that could trigger rejection. I can start immediately and will deliver a signed .ipa with TestFlight-ready build plus documentation so you're fully self-sufficient for future submissions.

Hi, I’m Abhishek Rathore, a senior mobile engineer. You have a Base44 web app that needs a compliant iOS wrapper with native subscriptions and App Store approval—I’ll build that bridge cleanly. ? Approach I’ll create a Swift-based iOS container using WKWebView for your existing app, and integrate StoreKit 2 for subscriptions. Receipt validation will use Apple’s App Store Server API with server-side verification. ✅ Core Features • Native iOS wrapper aligned with App Store guidelines • Full subscription flow: purchase, restore, renew, cancel • StoreKit 2 integration with async purchase handling • Secure receipt validation + backend callbacks • Web-to-native bridge for subscription state sync • Early audit of UI/flows for App Store compliance issues ☁️ Reliability / Performance I’ll isolate purchase logic natively to avoid WebView edge cases, handle interrupted transactions, and support App Store Server Notifications V2 for renewal events and retries. ? Deliverables • Signed .ipa for TestFlight • Clean Xcode project • Setup notes for certificates, builds, and resubmission • Subscription test plan on real devices ? Why Me Built similar wrappers with subscriptions (e.g., Rhythm app), passing review on first attempt. Do you already have subscription products configured in App Store Connect, or should I set those up as well?

Hi, This is really an App Store compliance and subscription-state problem, not just a wrapper task. The goal is to make your Base44 app feel native enough for Apple, while keeping subscription purchase, restore, renewal, and account access consistent end to end. The biggest failure point here is usually entitlement drift between StoreKit, the wrapper, and the backend. That is where users get charged correctly but access does not unlock, restore breaks, or Apple flags the app because the web layer still hints at non-IAP purchase paths. I’d approach this by keeping the wrapper thin, moving subscription control into a native StoreKit flow, and making backend validation and entitlement sync explicit so subscription state stays reliable across the full lifecycle. I’d start by auditing the current web subscription UX against Apple rules before wiring StoreKit.

Hi I can help you turn your existing Base44 web app into a compliant iOS wrapper with full Apple subscription support and App Store–ready native integration. The key challenge here is that many web-based wrappers fail review because their purchase flow or subscription messaging conflicts with Apple’s StoreKit and App Review guidelines, so I’ll audit the current interface first and flag any risky areas before implementation. I’ll build a native Swift/WKWebView container, integrate StoreKit 2 for purchase/restore/renew flows, connect receipt validation plus App Store Server Notifications to your backend, and ensure subscription state stays synced with your existing platform. I’ll also configure signing, provisioning, and App Store Connect integration so you receive a signed .ipa for TestFlight along with documentation for future resubmissions. My experience includes StoreKit, App Store review compliance, iOS app packaging, certificate management, and debugging subscription flows on physical devices. And I can help you so on by keeping the wrapper lightweight and maintainable while preserving your tested Base44 experience. Once subscriptions run end-to-end on real devices and TestFlight approval is confirmed, the implementation will be production-ready. Thanks, Hercules

I can help you wrap your existing Base44 app into a proper iOS container and implement the native hooks you need for Apple’s requirements. I’m very familiar with web-to-native wrappers, native SDK integrations, and the specific review expectations of the App Store. I’ve previously taken web-based and low-code apps, wrapped them for iOS, and added native capabilities such as push notifications, deep linking, in-app purchases, and App Tracking Transparency prompts. This includes preparing apps for successful App Store submission and handling common rejection reasons. My approach would be to review your current Base44 build, design a lightweight native shell in Swift/SwiftUI, integrate the needed native APIs, and ensure performance, permissions, and store metadata all align with Apple guidelines. I would love to chat more about your project! Regards

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience handling similar iOS wrapper and App Store submission projects and I'm available to start your project right now. I bring deep expertise in Swift, iOS Development, StoreKit, Xcode, Backend Development, and App Store deployment with over 10 years of experience. One of the key challenges in projects like this is wrapping a web-based app in a way that feels native enough for App Store review while implementing Apple subscription rules correctly, so I would build a clean iOS container for your Base44 app, integrate the full StoreKit subscription flow (purchase, restore, renew, manage), handle receipt validation and backend callbacks, and flag any UI or policy conflicts early before TestFlight submission. I have a couple of quick questions. • Is your backend already prepared to receive Apple subscription webhooks and receipt validation results? • Are the subscription products already created in App Store Connect, or should I help with that setup too? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos
