I have the complete source code for a mobile app and now need it published on both Google Play and the Apple App Store. The build, signing, and submission steps for APK/AAB and IPA are where I need you to jump in. Because I’m not certain which minimum Android SDK level or iOS deployment target is safest right now, I’ll rely on your recommendation there. Please suggest sensible, up-to-date version thresholds that will maximise device coverage without risking rejection. On the store-front side I’ll prepare most of the wording and graphics, but I do want partial help: a quick review of my descriptions, guidance on required screenshot sizes, and a check that the listing metadata meets each store’s rules. Deliverables • Compiled, signed, and successfully submitted builds on both stores (ready for review or already approved). • A brief hand-off note outlining the exact versions, certificates, and steps you used so I can reproduce the process on future updates. If you’ve recently navigated the latest Play Console and App Store Connect changes, this should be straightforward. Let me know your timeline and the toolchain you prefer (Xcode, Android Studio, Fastlane, etc.), and we can get started right away.
