UX audit costs in the UK typically range from £1,500 to £8,000 depending on the scope and complexity of the product. A focused audit covering a single user flow or key conversion path starts at the lower end. A comprehensive audit covering full user journey mapping, analytics review, heatmap analysis, stakeholder interviews, and a detailed recommendations report sits at the higher end. At Exline Labs, we scope every audit to your specific product and goals, so you only pay for what's actually useful. We give you a clear cost estimate in the first call.

A UX audit is a diagnostic. It identifies what's broken, where users drop off, and what's blocking conversions. You receive a detailed report with prioritised recommendations, but your existing product remains unchanged. A UX redesign takes those findings and acts on them - restructuring information architecture, redesigning flows, and delivering new UI ready for development. An audit is the right starting point if you want clarity before committing to a full redesign. Many of our clients begin with an audit and move into a redesign once they know exactly what needs fixing.

A UX audit evaluates your website or app's usability, clarity, and design effectiveness. We assess user journeys, accessibility, conversion paths, and make actionable recommendations.

Good UX design removes friction from the user journey, clarifies actions, and guides visitors toward key goals like signups or purchases — improving conversion rates significantly.

UX focuses on the overall user journey and experience, while UI is the visual layout and interaction. We combine both to create seamless and visually compelling digital products. Read our full UX vs UI breakdown if you want to go deeper.

Yes, our design system development services are ideal for startups preparing to scale. We create reusable components and documentation to support fast, consistent growth.

Absolutely. Our mobile UI design approach ensures your product is responsive, intuitive, and optimized for small screens as well as large displays.

We can share a detailed quote once you share some specifics about the product you have in mind.

It doesn't take that long. Usually, we can go from the discovery call to deployment in about 12 weeks.

We use open source tools and ecosystems, with local deployment to develop your project. Therefore, your data is not shared with third parties.

You. We do all our development projects on a work-for-hire basis. Clients own all rights for the work we do on their behalf.

Mobile app development in the UK typically ranges from £2,000 for a simple MVP to £50,000 or more for a full-featured custom app. The main cost drivers are the number of features, whether you need iOS, Android, or both, the complexity of your backend, and whether you choose cross-platform (Flutter or React Native) or native development. Cross-platform is generally more cost-effective for startups needing to reach both platforms quickly. For a full breakdown of what affects mobile app costs, read our UK mobile app development cost guide.

Yes. We build cross-platform mobile apps using both Flutter and React Native depending on what suits your project best. Flutter is ideal for apps that need a highly custom UI and fast launch timelines. React Native works well when you need a large plugin ecosystem and fast iteration. Both deliver a single codebase that runs on iOS and Android, keeping your build cost and timeline down. Not sure which is right for your app? See our 2026 comparison of Flutter, React Native, and other frameworks.

Yes - we develop native apps for iOS and Android as well as cross-platform apps using Flutter and React Native. We choose the best stack based on your project needs and budget.

Absolutely. Our team builds AI-integrated mobile apps with features like predictive search, smart analytics, recommendation engines, and chatbot support.

Yes, we assist with App Store and Google Play submissions, compliance requirements, security standards, and post-launch support.

We've worked with sports, healthcare, SaaS, logistics, and educational businesses across the UK, EU, and New Zealand - building mobile solutions that solve real-world problems.

Yes. Most of our mobile app developers are based in Sri Lanka, but we have experience working UK hours with multiple clients.

For a focused MVP mobile app, our process runs from 6 to 8 weeks. Week 1 for discovery and user research, Weeks 2 to 4 for UX design and flows, Weeks 5 to 7 for development, and Week 8 for testing and launch. More complex apps with advanced features, AI integration, or multi-platform requirements typically take 10 to 12 weeks. We work in structured sprints so you see real progress throughout the build, not just at the end.

We can start with a Zoom meeting to kick off and we'll keep in touch via email and WhatsApp during the project. Our past clients appreciate our prompt response times and clear communication. Just check our reviews.

We can give a detailed quote, with the timeline, once you share the specifics. Would you like to book a free consultation call?

A prototype is a clickable design used to test an idea, and it looks like a product but has no working code behind it. An MVP (minimum viable product) is real, functioning software that actual users can sign up for, interact with, and give you data from. A prototype answers "does this make sense?" An MVP answers "will people use this and pay for it?" Most of our clients start with a short prototype sprint to validate the UX concept, then move straight into the MVP build.

Most UK MVP projects fall between £10,000 and £80,000 depending on complexity, feature scope, and whether the product includes mobile, AI, or third-party integrations. A lean MVP with a single core workflow typically starts at £10,000–£30,000. A full investor-ready product with auth, dashboard, and integrations is usually £30,000–£60,000. Complex builds involving AI features or multi-platform delivery can exceed £60,000. We give a detailed cost estimate in our first scoping call and no obligation.

Most MVPs we build ship within 6 - 8 weeks from the start of the project. The first 1 - 2 weeks cover discovery and UX design, weeks 2 - 7 are the build, and the final week is testing, QA, and launch preparation. More complex products with AI features or multiple platforms can take 10 - 12 weeks. We work in focused sprints so you're seeing real progress, not waiting months to see anything. If speed is critical, we can discuss what's achievable in your specific timeline in the scoping call.

We can help you define the core problem your software needs to solve and prioritise features using the MoSCoW method (Must have, Should have, Could have, Won't have).

They like products that have a clear solution for a problem, proven market demand, and numbers and feedback to validate potential. An MVP is the easiest way to demonstrate these.

Yes - we specialize in building investor-ready MVPs that showcase traction, usability, and product potential. Our designs focus on clear user flows, measurable outcomes, and visual polish to help you impress early-stage investors.

Yes. AI-powered MVPs are one of our fastest-growing service areas. We build products that integrate large language models (LLMs), custom AI pipelines, intelligent automation, and AI-assisted features into working MVPs. We use the same 6-8 week sprint framework, scoped around the AI capabilities your product actually needs, not a bloated feature list. If you're building with OpenAI, Anthropic, or custom models, we can scope what's viable and deliverable within your timeline and budget.

Absolutely. Our MVP process includes early-stage market research, user interviews, and live feedback loops to ensure your product aligns with real customer needs. We prioritize features that deliver the most value from day one.

We've worked with startups and SMEs in SaaS, healthcare, fintech, HR tech, sports, logistics, and more across the UK, Germany, France, Ireland, and New Zealand.

We offer packages on a monthly, annual, or bi-annual retainer basis to suit your development needs.

We work with clients looking for a long-term development partner, but we do not lock you in with a minimum commitment.

No, but there is no lock-in either. If it doesn't work, either party can cancel the contract with a month's notice.

You! Our extended team works on a work-for-hire basis. You own the intellectual property of all the projects.

Yes. Though most of our team is based in Sri Lanka, they're experienced with working with UK clients in GMT/BST time.
