Mobile App Development
iOS and Android apps from one Flutter codebase, designed and built by GBCORP engineers: customer apps, business and enterprise apps, commerce and marketplace apps, on-demand services and the modernisation of apps you already run. Scoped in a week, quoted at a fixed price per release.
What we build
Mobile application development for the apps a business runs on, sells through or hands to its customers.
Customer mobile app
A branded app your customers open every week: accounts, loyalty, ordering, booking, notifications and support, on both stores.
Business mobile app and enterprise mobile app
Apps for staff, field teams and operators: tasks, scanning, approvals, offline-tolerant screens and role-based access.
Mobile commerce app
An ecommerce mobile app or marketplace mobile app with catalogue, cart, checkout through your gateway and a merchant dashboard.
On demand app development
Booking, ordering, delivery and service apps with customer, provider and operator roles, live status and payments.
Every mobile app development service
The full range, from one codebase and one team.
iOS app development and iPhone app development
Native iOS builds with sign in with Apple, Apple Wallet passes, push notifications and App Store publishing handled by GBCORP.
Android app development and Android application development
Native Android builds with Google Wallet passes, push notifications and Google Play publishing, released together with iOS.
Flutter app development and cross platform app development
One Flutter codebase compiled natively for both stores and the web. GBCORP is a Flutter development company by choice: one team, one release, half the cost of two native builds.
Custom iOS app and custom Android app
When a product needs platform-specific features, the same codebase carries native modules for each store without splitting the project.
Mobile app design and development
Screens designed for the way people hold a phone, tested on a live build before they are polished, with accessibility and multilingual layouts built in.
React Native app development
For clients already running on React Native, GBCORP maintains and extends the app rather than forcing a rewrite.
App modernization and legacy app modernization
Old apps moved to a current codebase in stages: same store listing, same users, same data, with every release live.
Marketplace and multi-role apps
Buyers, sellers, suppliers and drivers in one product, each with their own view of the same backend and an operator console behind it.
Whatever you call it
Buyers search for the same capability under many names.
Mobile application development, mobile app design and development, custom mobile app development or simply an app for the business: GBCORP delivers each from the same production-proven foundation. The blocks a mobile app needs, accounts, payments, loyalty, wallet passes, notifications, maps, multilingual layouts and an operator console, already run in GBCORP's own apps, which is why a customer mobile app, an enterprise mobile app or a marketplace mobile app ships in weeks rather than quarters.
How a project runs
Four stages, each with a fixed outcome.
1 · Scope in a week
Workshops, screens and a written scope for the first release, ending in a fixed quotation.
2 · Build in releases
Two-week sprints on a live test build you can open on your phone. Every release is usable.
3 · Launch on the stores
App Store and Google Play listings, review handling, web deployment and analytics from day one.
4 · Run and improve
Monitoring, security updates, store compliance and new features under a support plan, or a full hand-over.

Questions about mobile apps
The questions we hear first, answered plainly.
Do you build native iOS and Android apps or cross platform?
Cross platform app development from one Flutter codebase, compiled natively for iOS app development and Android app development at the same time. It behaves like a custom iOS app and a custom Android app, without two teams and two bills. React Native app development is available where a client already runs on it.
How much does mobile app development cost?
A branded app on a GBCORP white-label engine is a flat monthly plan and is live within days. Custom mobile app development starts with a one-week scoping exercise that ends in a fixed quotation for the first release; the priced starting point is on the GBCORP e-shop.
Can you modernise our existing app?
Yes. App modernization and legacy app modernization move an old app onto a current codebase in stages, keeping the store listing, the users and the data, with each release live and usable.
Which kinds of app do you build most?
Business mobile apps and enterprise mobile apps for staff and operations; customer mobile apps for brands; mobile commerce apps, ecommerce mobile apps and marketplace mobile apps for selling; and on demand app development for booking, ordering and delivery.
Do you handle the App Store and Google Play?
Yes. Store accounts in your name, listings, screenshots, review handling and updates are part of every project, with analytics from day one.
Who owns the app afterwards?
You do. Source code, cloud project and store accounts are in your name from the start; GBCORP can keep improving the app under a support plan or hand it over.
