Web & mobile applications
When your business needs software that does something — bookings with your rules, accounts, payments, field work that survives a dead signal — a template stops being an option. We build bespoke applications for web, iOS, and Android from one codebase, engineered around your exact workflow.
One codebase, every screen
Building an app three times — web, iOS, Android — triples your cost and splits your team's attention. We build once: one codebase that ships to the browser as a fast web app and to both app stores as native packages, sharing the same business logic everywhere.
That's not a compromise stack; it's how this site's own platform runs, and it means every fix and feature lands on all your users at once.
Real business logic, not glued-on features
The value of a custom app is in the rules that make your business yours: how a booking is priced, who approves what, when a reminder fires, what a customer may see. We design the data model around those rules first, then build the screens on top.
Payments, one-time-code login, notifications, document handling, and offline behaviour are all standard scope — precisely the things templates and low-code tools do badly.
Shipped, published, supported
We carry the build through the unglamorous last mile: app-store publishing, crash monitoring, analytics, and updates. Launch includes a defined support window, and ongoing SLAs keep response times in writing.
As always: your brand and data are yours, and buying out your app's source code is an option in the agreement; VantyRex's backend logic and infrastructure stay ours and are never handed over.
What it costs and how long it takes
A custom app (a web app plus iOS and Android builds from one codebase) typically takes 8 to 12 weeks from signed contract to launch. Starting prices for your market are on the pricing page, and your quote confirms its own timeline.
It starts with a 15-minute call. Within 48 hours you get a fixed written quote, and we build under a signed contract with milestones, so you see progress at each one rather than at the end.
Typical starting prices
Web or mobile app: from $27,000 (excl. taxes)
Every project still gets its own fixed written quote within 48 hours of the 15-minute call.
FAQ
Native or cross-platform — what do you recommend?
For most business applications, one shared codebase wins: lower cost, faster iteration, one team. We'll tell you honestly when a requirement (heavy 3D, specialised hardware) genuinely justifies fully native — that honesty is cheaper than discovering it late.
Can the app and our website share one system?
Yes — and they usually should. One backend serving your site, your app, and your admin means one source of truth and no double data entry. That's the architecture we default to.
Do you publish to the App Store and Google Play?
We prepare the builds and guide you through app-store review. The Apple and Google developer accounts are opened in your name, and their fees are not included in our price.
