Interactive tests
Question-based applications with navigation, scoring, feedback and results, such as practice and assessment tools.
Web application development and PWA UK
Build a useful digital tool, then make it easy to return to.
Practical browser-based applications and Progressive Web Apps for businesses, learning and testing — from focused interactive tools to custom web solutions.
From idea to useful tool
Make a process easier for the people using it.
A web application can turn a repetitive process, learning activity, calculation or test into a clearer digital experience.
I can help define the purpose, structure the user journey and build a practical browser-based tool that works across desktop and mobile.
Discuss Your ApplicationWhat can be built?
Focused applications for real use cases.
Calculators and estimators
Tools that accept user inputs, apply defined logic and return useful calculations or recommendations.
Learning tools
Structured browser-based experiences for teaching, revision, practice and accessible digital learning.
Business tools
Focused tools that simplify an internal process, customer interaction or repetitive task.
Data-driven interfaces
Applications that organise content, choices, results or structured information for users.
Custom front-end experiences
Purpose-built interfaces designed around a clear user journey rather than a generic page template.
Progressive Web Apps
Turn a web application into an installable experience.
Suitable applications can be enhanced with PWA features such as a web app manifest, custom icons, installation support and a practical offline experience where the project allows it.
Ask About a PWA Version
01
Installable
Users may be able to add the application to a phone home screen, desktop or app launcher on compatible devices.
02
App identity
Manifest, name, theme colour, icons and launch behaviour create a more app-like experience.
03
Offline-ready options
A simple offline fallback or more advanced offline functionality can be scoped according to the application.
04
Optional enhancement
PWA features are priced separately because offline data, synchronisation and notifications add technical complexity.
Starting prices
A sensible starting point for different project sizes.
Final pricing depends on features, content, data, authentication, integrations, testing and ongoing support.

How it works
Build the right amount of technology.
The goal is a useful application with a clear scope, not unnecessary complexity.
01
Define
Clarify the users, problem, inputs, outputs and essential features.
02
Structure
Plan the user journey, screens, logic, content and technical approach.
03
Build
Develop the agreed application and test its behaviour across relevant devices.
04
Launch
Provide launch guidance, handover notes and options for future maintenance or PWA enhancements.
Important scope notes
The starting price depends on the brief.
Included in the quote
Features, screens, content, data sources, testing requirements and launch arrangements are defined before development begins.
Quoted separately where needed
Accounts, payments, large databases, APIs, complex integrations, push notifications and advanced offline synchronisation may require a larger scope.
Frequently asked questions
Before you build an application.
Can you build a PWA for an existing application?
Yes, if the application structure is suitable. The work may include a manifest, icons, service worker, installation support and appropriate offline behaviour.
Will the application work fully offline?
Not automatically. Full offline operation requires appropriate caching, local data handling and possibly synchronisation. It is scoped separately.
Can users install it on their phones?
On compatible browsers and devices, users may be able to add the application to their home screen or install it as an app-like experience.
Are push notifications included?
No. Push notifications require additional permissions, service-worker work and often server-side handling.
Can you build a mock test or quiz?
Yes. Interactive tests can include questions, navigation, scoring, feedback, results and optional PWA features.
Have an idea?
Discuss your web application or PWA.
Tell me what the application should help users do and whether installability or offline use would be valuable.
