GBCORP · AI & IT
Custom App Development
iOS, Android and web apps built by GBCORP engineers: one Flutter codebase, a cloud backend, payments, wallet passes and an operator console. Scoped in a week, quoted at a fixed price, delivered in releases you can use from the first one.
What we build
Business apps that customers, staff and operators use every day, engineered by the team that runs GBCORP's own apps.
iOS and Android apps
One Flutter codebase for both stores and the web, with native sign-in, push notifications, wallet passes and offline-tolerant screens.
Web apps and portals
Customer portals, merchant dashboards and internal tools on the same backend as the mobile app, so nothing is built twice.
Marketplace, ordering and delivery
Listings, carts, cut-off times, delivery zones, promo codes, card and regional payments, and the console that operators run the business from.
AI-powered features
Assistants, content moderation, recommendations and automation built into the app with GBCORP's AI engineering team, not added as a chatbot on the side.
How a project runs
Four stages, each with a fixed outcome, so you always know what comes next and what it costs.
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, not a demo.
3 · Launch on the stores
App Store and Google Play listings, review handling, web deployment on your domain 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 of code and accounts.
Already built, ready to brand
If your idea matches a product GBCORP already runs for its clients, a white-label launch is faster and cheaper. We will tell you.
Why businesses choose GBCORP
What a client gets beyond the code.
Fixed price per release

Production-proven blocks
Payments, loyalty, wallet passes, multilingual layouts, e-mail and security are already in production across GBCORP products.
One team, 17 countries

Priced and ready to buy
Flat prices on the GBCORP e-shop for the first release. Customised or more complex functionality is quoted separately.
Questions about custom apps
The questions we hear first, answered plainly.
How much does it cost to build an app?
It depends on what the app must do. A branded app on a GBCORP white-label engine is a fixed plan and is live within days. A custom app starts with a one-week scoping exercise that ends in a fixed quotation for the first release, so you know the cost before any code is written.
Can GBCORP build an app like Uber, Airbnb or DoorDash?
Yes. Marketplace, booking, ordering and delivery apps share the same building blocks: accounts, listings, payments, notifications, maps and an operator console. GBCORP has these blocks in production and assembles your version around what makes your business different.
Which platforms do you build for?
iOS, Android and the web from one Flutter codebase, with a cloud backend, your payment gateway, and Apple and Google Wallet where the product needs it. Web-only products and internal tools are built the same way.
Who owns the code?
You do. Custom projects are delivered with the source code, the cloud project and the store accounts in your name. GBCORP can keep running and improving the app under a support plan, or hand it over entirely.
How long does a custom app take?
A first release of a focused business app typically takes six to twelve weeks after scoping. Larger platforms are delivered in releases, each one live and usable, so value arrives early rather than at the end.
Do you work with startups?
Yes. For a startup the usual path is an MVP on a fixed scope, launched on the stores, then iterated with real users. Where a white-label engine already covers the idea, we say so, because it is faster and cheaper.
