Software prototyping services by Square Root Solutions UK help reduce project risks and speed up delivery. We offer app and web prototype creation in the UK with digital product design, low and high-fidelity prototypes, ready for stakeholder and investor presentations.
As a top software development company, we are recognised as software prototyping experts and UK product design specialists. We work as agile prototyping partners delivering both low and high-fidelity prototypes. With a proven track record with UK clients, we offer end-to-end product design services and flexible engagement and pricing models.
Our experienced UX/UI designers in the UK, supported by work delivered from UK-based design teams, have completed 100+ prototypes delivered for UK industries. Using an agile methodology for faster turnaround, we provide a dedicated UK-based project manager and follow transparent pricing and delivery milestones to ensure efficiency and clarity.
Our best-in-class software prototyping services cover web, mobile, and SaaS prototypes, using Figma, Adobe XD, and Sketch to design for real-user testing before development. From concept sketches to interactive models, we align with agile development handover to test product ideas before coding.
We use wireframing tools for low-fidelity prototype design that define information architecture and create early-stage app sketches. Delivered using Figma and Balsamiq, these focus on core navigation and layout flow with iteration cycles within 48–72 hours for rapid improvements.
Our high-fidelity designs and interactive mockups deliver pixel-perfect UI prototypes. Built in Figma, Adobe XD, or Sketch, they simulate the final product UI/UX, include animations and transitions, and offer screen-level precision for user testing.
We create proof of concept builds for feasibility testing and technology validation. Delivered in 2–4 weeks, these validate business ideas, test technical assumptions, and cover core functionality with minimal resources for maximum validation and technical risk assessment.
Our MVP prototyping focuses on lean product builds for early-stage market launch. Built in 6–8 weeks, these launch with essential features, reduce time-to-market, use scalable architecture, integrate analytics, and stay aligned with agile development principles.
We run usability testing for UI/UX validation with the target audience. Using UK-based panels, we collect insights through heatmaps and click-path analytics, record sessions, and apply iterative refinements post-testing to enhance design before development.
Software prototyping is the process of creating an early working model to test features, design, and usability before full development. It delivers early-stage design benefits, enables business product validation, and helps validate product–market fit in the UK. Prototyping minimizes costly rework during development, supports faster stakeholder decision-making, and encourages innovation with visual proof.
It reduces risk before development, helps secure funding with visual concepts, and accelerates go-to-market strategies. By following a structured software prototyping process, UK businesses can streamline approvals, ensure market alignment, and confidently invest in solutions that meet both user needs and commercial goals.
We provide business-oriented industry-specific prototyping solutions with domain-focused UX/UI testing to deliver tailored prototypes for regulated sectors. Our business-driven design strategies ensure industry-compliant designs for UK regulations. Services include sector-specific feature mapping, support for integration with domain tools, and prototypes ready for multi-platform launches.
Our prototype development lifecycle follows an agile design workflow with user feedback integration and step-by-step milestone tracking. It includes user testing at each stage, is designed for faster iteration cycles, and is optimized for development-ready deliverables through an iterative design and testing process, collaborative design reviews, and rapid prototyping with feedback loops. We ensure clear handover to development teams for smooth implementation.
We define goals through detailed requirement gathering and user research. This phase identifies target users, captures business needs, and sets the direction for the prototype.
We create wireframes that outline navigation, layout, and structure. This step validates core flows before moving to interactive design stages.
We design interactive prototypes with realistic UI/UX. Each build undergoes user testing to confirm usability and identify improvement areas.
We integrate feedback into the final prototype and ensure all deliverables are ready for a clear development handover.
