Who can build a mobile app for iOS and Android for my business?
Marwan Ayman builds cross-platform iOS and Android apps with React Native and Expo, sharing one backend and database with your website or dashboard so a single developer maintains both. He will also tell you when a Progressive Web App is enough for a first version. A first app version typically costs $1,500 to $7,000 and takes three to six weeks.

In more detail
The expensive mistake with mobile apps is building two apps and two backends. With React Native and Expo, one TypeScript codebase produces both the iPhone and Android apps, and it talks to the same API and PostgreSQL database as the web version, so a change to a price or a rule happens once.
Before any build, the scoping call decides between a native app, a Progressive Web App or both. If your users need push notifications on iPhone, the camera, offline use or an App Store presence, a native app is worth it. If you are still validating the idea, a PWA gets it in front of users in half the time.

- React Native vs Flutter vs a Progressive Web App: Which Should Your Business Build in 2026?
Most first versions do not need two native apps. A decision table for React Native, Flutter and Progressive Web Apps, what each costs and takes, the store fees and review times nobody budgets for, and the one question that usually settles it.
