Mobile app development for iOS and Android
We take your product to the App Store and Google Play with maintainable code, backend integrations, and UX designed for end users — not prototypes that don't scale.
Apps we've built at Genbia
Real interfaces from products we developed: from food orders and healthcare to logistics. Each project starts from your domain and brand; here you only see examples of polish and flow level.
Food orders and delivery
End-user app with location, cart, promotional banners, categories, and listings with ratings — ready to connect to your catalog and delivery rules.
Healthcare and doctor appointments
Clinical marketplace experience: specialist search, highlighted next appointment, specialties carousel, and doctor profiles with ratings and favorites.
Last-mile logistics (client)
Golleva ecosystem home screen: shipment summary, active orders, and access to create shipments — same stack as the delivery platform we document in Software delivery.
We work cross-platform as the case requires; we specialize in Expo when time-to-market and a single team for multiple mobile surfaces makes sense. Below you'll see screenshots of apps we developed: food delivery, healthcare with medical appointments, and a logistics client (Golleva reference).
Production-ready UX
Clear navigation, loading and error states, basic accessibility, and design consistent with your brand.
Real-time data
Orders, location, push notifications, and sync when the business requires it.
Publishing and CI
Builds with EAS or other pipelines, environment variables, and store review.
What's included
- React Native / Expo
- Push, deep links, and OAuth per integration
- Maps, camera, and foreground/background permissions
- In-app payments when applicable
- Complementary web panels in the same project when needed
Estimated investment — mobile apps
iOS and Android apps with Expo/React Native, backend, push, payments, and integrations are sized by functionality and operations. These ranges help you plan.
Plan A
$5,000 – $10,000 USD
MVP or focused module with core integrations
Plan B
$10,000 – $20,000 USD
Broader scope, multiple roles, and production operations
What affects cost
- Degree of customization and functional scope
- Technology stack (frontend, backend, infrastructure)
- App store publishing, push notifications, and in-app payments
- Offline sync, roles, analytics, and dedicated backend
Ranges are indicative. Final cost is defined after reviewing scope, timeline, and technical complexity.
Frequently asked questions
Native (Swift/Kotlin) or cross-platform?
We evaluate performance, budget, and team: many B2B and delivery products work very well with Expo/React Native; if a module requires pure native, we isolate it.
Are the portfolio screenshots templates?
They are screens from apps developed by Genbia or the Golleva ecosystem that we show as technical and design reference; your product carries your brand and rules.
