Mobile app development for UK businesses
We plan, build and launch apps for customers, staff and field teams, connected to the systems your business already uses.
What does EsquireTec’s mobile app service include?
EsquireTec builds iPhone and Android apps, usually from one cross-platform codebase (Flutter or React Native), which is quicker to build and easier to maintain than two separate apps. Apps connect to your website, ERP, CRM and payment provider through secure APIs, and we handle the App Store and Google Play submissions and the updates after launch.
Why your business needs professional mobile app development
A mobile app puts your business on your customer’s home screen. It lets them order, book, pay, track and get notifications in a couple of taps, and it gives your staff the same power in the field. A good app feels simple, but behind it sits careful design, secure data and a reliable connection to your systems.
We plan the app with you screen by screen, build it for iPhone and Android, connect it to your website, ERP or CRM, and publish it on the App Store and Google Play under your own accounts. After launch we keep it updated as phones and operating systems change.

What affects the cost and timeline?
Every job gets a clear, itemised quote after a free call, so you know the cost before any work starts. These are the main things that shape the quote:
Screens & user roles
More screens and roles (customer, staff, admin) mean more design and testing.
Integrations
Payments, maps, ERP, CRM and third-party APIs each add work.
Admin panel
Most apps need a web dashboard to manage users, content and orders.
MVP or full product
Starting with a focused first version controls budget and time to market.

Mobile app development FAQs
How much does it cost to build a mobile app?
Cost depends on the number of screens, user roles and integrations, and whether you need an admin panel. Many projects start with a smaller first version. Every job gets a clear, itemised quote after a free call, so you know the cost before any work starts.
Do you build for both iPhone and Android?
Yes. We usually use a cross-platform framework so one codebase runs on both. A fully native build is available when an app needs it.
Can the app connect to my existing system or website?
Yes. We build secure APIs so the app shares customers, orders, stock and bookings with your ERP, CRM or website.
Who owns the app?
You do. We publish under your own App Store and Google Play developer accounts and hand over the source code.
