What we do
Flutter Mobile App Development (Android & iOS)
Flutter lets one codebase run on both Android and iOS, which keeps development and maintenance costs down. We build mobile apps that connect to your existing systems and give customers or staff what they need on the go.
Who it’s for
- Businesses that want an app for their customers
- Teams that need field or staff apps
- Existing web platforms that need a mobile companion
What you get: You end up with one app on both Android and iOS from a single codebase, with releases you can keep shipping.

Why VLEONS
Reasons clients stay with us
Full-stack experience
ASP.NET Core, C#, Angular, Flutter, WordPress and SQL Server, used on live business systems — not a single-stack shop learning on your project.
Custom development, not templates
Every build starts from your workflows. We write the theme, the modules and the integrations, so nothing is bent around a template you did not choose.
You talk to the people building it
No account manager relaying messages. You work directly with the team responsible for your project, with the scope and price agreed in writing first.
Built to grow, supported after launch
Architecture that takes new modules without a rewrite, and support once the project is live — the work we did for Zuriyat Foods and Sublime Care Cloud is still running.

A project like yours
Sublime Care Cloud
The problemBusinesses run operations across disconnected tools and spreadsheets, and every new area of the business usually means another custom screen to build and maintain.
What we builtAn ERP platform built around a metadata engine: JSON field definitions generate both the forms and the tables, so a new module can be added from configuration. The Angular admin client handles role-based access and module routing, a .NET API and SQL Server sit behind it, and a self-service report builder lets staff assemble their own reports.
The resultOperations, customers and reporting run on one platform, and new modules no longer require a rewrite of the screens around them.
How we work
Four stages, no surprises
Discovery
We map what you need, who uses it and what success looks like, then put the scope and a fixed price in writing.
Design
Structure and interface first, agreed with you before any production code is written.
Development
Built in stages you can see, with testing, performance and security handled as we go.
Launch
Deployment to your hosting, handover of everything you own, then support and improvements.
Questions
Before you enquire
What does Mobile App Development cost?
It depends on scope. We look at what the project needs, then send a written proposal with a fixed price before any work starts, so there are no surprises later. Payments are 50% to begin and 50% before deployment.
How long does it take?
Timelines follow scope, not a price list. Every proposal includes a schedule with the stages and what each one delivers, and we tell you up front if something in your list will stretch the timeline.
Who owns the work when it is finished?
You do. We deploy to your hosting and hand over the complete source, files and accounts. Hosting, domains and premium licences stay in your name and are paid separately.
What happens after launch?
We stay available for support, fixes and improvements. Projects we built are still live and maintained, and you can keep us on for ongoing work or take it in-house with the handover documentation.
Which technology do you use for this?
For this service: Flutter, Dart, REST APIs, ASP.NET Core. We choose per project instead of forcing every client onto the same stack.
Can you work with what we already have?
Yes. A lot of the work is modernising, integrating or extending systems and websites that are already running, rather than starting from zero.
