It sounds like the app is already past the heavy development phase and the main challenge now is getting everything Apple-facing finalized without running into subscription or review issues. I’d start by auditing the current Base44 mobile wrapper, App Store Connect configuration, RevenueCat setup, and existing IAP products to identify anything that could cause submission delays. From there, I’d validate the full subscription lifecycle—purchase, renewal, cancellation, restoration, and entitlement handling—using Apple’s sandbox environment and TestFlight builds. Once that’s stable, I’d review privacy disclosures, account management flows, permissions, and onboarding against App Review requirements to catch rejection risks before submission. I recently worked on subscription-based mobile workflows where the biggest issues weren’t bugs themselves, but edge cases around entitlement syncing and restore purchases, so I pay close attention there. One thing I’d also verify is that users can clearly manage subscriptions from within the app, which helps avoid common review feedback. Do you already have the App Store Connect products and RevenueCat entitlements created, or does that still need to be configured? I’m ready to jump in and help get it across the finish line.

Hi, I’m Osama from Virginia. I understand that you need Core Level finalized for iOS launch, and the main priority is to get the app stable, compliant, and approved in the App Store with subscriptions working correctly. I can help clean up the current mobile setup, resolve remaining issues, and move the release forward without unnecessary rebuilding. I have experience with mobile app development, App Store Connect, TestFlight, RevenueCat, and subscription-based app workflows. For this project, I would first review the current Base44 wrap, iOS configuration, and submission status, then focus on IAP setup, entitlement validation, bug fixing, and App Store compliance checks so the app is ready for review. My approach would be: • Review the current requirements and confirm the main acceptance points. • Check the existing structure and prepare the best setup for launch. • Implement and validate subscription and purchase flows step by step. • Test the key user paths, fix issues, and reduce rejection risks. • Provide clear updates during development and deliver a proper handover. One question: do you already have the Apple Developer account, App Store Connect access, and RevenueCat project configured? I’m available to start anytime and can work full-time. I look forward to discussing the project with you. Regards, Osama

@codeandcommand

The RevenueCat integration is where things usually break when using Natively. Webhook handling and subscription state sync on app resume need to be solid, or users get locked out after purchase. I can start today and have the App Store build ready in about 5 days. Treat the bid as an initial estimate. Final numbers come after we walk through what is already done in Base44. Want to jump on a quick call?
