FAQ
My app was rejected by Apple. Can you help me resolve the rejection?
Yes! I will review the rejection notice from App Store Connect, inspect your codebase, modify the app's metadata or logic to comply with Apple's Guidelines (such as Guideline 4.0 or 2.1), and resubmit it for approval.
Do I need to share my Apple and Google developer account credentials?
To upload the app directly, you can either add my email address as a developer/manager in your App Store Connect and Google Play Console, or I can provide you with the compiled release files (AAB/IPA) along with step-by-step guidance.
Can you implement Stripe payment gateway in Flutter or React Native?
Absolutely! I will integrate the official Stripe SDK, set up payment sheet modules, configure secure webhooks, and ensure full PCI compliance.
what happens if a bug reappears after delivery?
I offer 30 days of free post-launch support to resolve any bugs directly relating to my work, ensuring your app runs smoothly and remains live in the stores.
