iOS & Android App Development in Hong Kong
We build cross-platform iOS and Android apps with React Native (Expo) and Flutter, and WeChat mini programs for mainland audiences — including payments, push notifications, in-app ads and the admin tools behind them.
What’s included
- UX flows and UI design for iOS and Android
- Cross-platform app with native modules where needed
- Back end, admin dashboard and cloud functions
- Payments: Stripe, Alipay, WeChat Pay
- App Store and Google Play submission
- End-to-end tests on real flows
Scope, costs & handover
Your proposal lists the pages or workflows, content you need to supply, review milestones and acceptance checks. Additional features are quoted before work starts.
Domain renewals, hosting, payment processing, AI API usage and other third-party fees are itemised where applicable. Ongoing maintenance is separate from new feature development. Code, accounts and operating notes are included in the agreed handover.
Common questions
Do I need separate iOS and Android apps?
Usually not. One React Native or Flutter codebase serves both stores, which roughly halves the cost of building and maintaining two native apps.
