A web app is an application that operates through a web browser rather than being installed on a device. Unlike static websites, web applications are interactive and allow users to perform tasks such as submitting forms, making payments, or managing data in real time.

The cost to build a web application ranges from £4,000 to £120,000 (pounds), depending on complexity, features, design requirements, and the development team's location. Basic web apps with limited functionality cost less, while enterprise-level applications with custom features, integrations, and advanced security charge high .

A web application takes 8 to 20 weeks to design, develop, test, and deploy, depending on its complexity and feature set. Projects with custom functionality, third-party integrations, and compliance requirements may take longer due to extended development and review cycles.

Web app development involves building interactive, functionality-driven platforms where users can perform actions, such as logging in, managing data, or completing transactions. Whereas, web development focuses on building both static websites and dynamic web apps that present content, such as blogs, portfolios, or company pages.

Our team will schedule a discovery call to understand your technical requirements, user needs, and business goals. Once the scope is defined, we will prepare a detailed proposal outlining the timeline, deliverable, and cost before moving towards the development process .
