Digital Subscription Mobile Shopping App

I need a customer-facing mobile app that lets people browse, purchase, and instantly access my digital products and recurring subscriptions. The flow is simple but must feel premium: account creation, catalog browsing, secure checkout (card, Apple Pay, Google Pay), immediate content unlock, plus a small area where users can view invoices, manage active plans, and cancel or renew without leaving the app. Push notifications for new releases and expiry reminders would be a plus. My product catalogue and licence system already sit behind a REST/JSON API with OAuth2, so your task is to build the iOS and Android front-end, connect to those endpoints, handle purchase validation, and prepare everything for App Store and Play Store submission. I’m flexible on tech—React Native, Flutter, or fully native—provided performance is solid and the codebase is easy for my in-house team to maintain. What you’ll hand over: • Source code (well-commented and version-controlled) • Build-ready binaries for TestFlight/Internal testing • A brief implementation document or walkthrough call covering setup, store submission steps, and future update procedures If you’ve shipped mobile apps with in-app purchases or subscription management before, especially for digital content, I’d love to see links or store listings when you reply.
