Multizone is a small, founder-led company. We do four things in mobile, plus our long-standing product and service health-checks, Joomla, and legal technology work. We say no to the rest.
If you are here for the App Modernisation managed service specifically, the home page is the right starting point. This page is for directors, founders and agency partners working out which Multizone service fits.
Multizone is a UK software development practice with decades of combined expertise across mobile, collaboration, legal technology, enterprise software, and operating systems.
The four mobile services
Each one covers a distinct point in the life of a mobile app:
Day rate
MVP App
You have an idea for an app and you want to find out, cheaply, whether it works in the real world. We build the smallest version that proves it.
- Day-rate consulting
- iOS and Android, single codebase
- Typically four to ten weeks
Fixed price + Maintain
Advanced App
Modernise an existing app at a fixed price, in two weeks. Then keep it healthy under our Maintain subscription, the work that stops the inevitable decline of a working app.
- From £4,995 one-off
- Maintain from £495 / month
- Twelve-month minimum, longer terms discounted
Fixed price + Enhance
Sophisticated App
Modernisation plus deeper feature and design work, then ongoing forward motion under our Enhance subscription. For apps that are now central to how customers experience the business.
- From £7,995 one-off
- Three-week delivery
- Enhance from £995 / month
- Includes a monthly engineering allowance
Day rate or retainer
App Platform
Your app is now business-critical and you need senior product and engineering oversight, not just delivery. Fractional CTO, governance and risk management.
- Interim or fractional CTO
- Governance and risk audits
- Senior product management
Joomla extensions
We publish a directory of extensions for the Joomla content management system (CMS), covering shared subscriptions, platform integration and supporting tools. A separate product line from the mobile services above, actively maintained since long before mobile took the headline.

Joomla: open-source CMS
- In continuous release since 2005, current major version Joomla 6
- WCAG 2.1 AA accessibility and WebAuthn passkeys in the default templates
- Security advisories from a dedicated Strike Team (JSST), publicly tracked CVEs
How we engage
Most engagements start with a single twenty-minute call. From there:
- Advanced App and Sophisticated App: free 24-hour audit, then a fixed-price proposal. See the App Modernisation home page for the full process.
- MVP App: scoping workshop, then day-rate engagement to ship.
- App Platform: initial audit, then interim mandate or fractional retainer.
- Joomla extensions: off-the-shelf via the extensions directory.
Built with Flutter
- Open source, created and maintained by Google
- One codebase compiled ahead-of-time for iOS and Android
- The most-used cross-platform mobile framework worldwide — 46% of developers in 2022 (Statista)
Sectors we have worked in
We have built and shipped apps across device testing, office collaboration, law enforcement, healthcare, education, and clubs and societies. Our professional services consultancy and product-management engagements have been in senior roles at technology companies in legal technology, collaboration, mobile technology, and telecoms. We will be clear if your sector falls outside what we know well.
