Solutions · Product
A UK app development agency taking software products from first prototype to production — design, engineering and delivery in one London team. You own the code at the end.
Solutions we've built power teams at:
From first prototype to production software, designed to launch and built to last.
A snagging platform handling thousands of defects on live construction sites, a chat and calling app for frontline workforces, and a consumer running app with thousands of verified routes. Different sectors, same end-to-end team.
A large London-based construction company managing major residential sites — dozens of contractors, thousands of defects — came to CodeLeap for a digital snagging platform. Within 6 months, we delivered a fully functioning mobile app that reduced human errors and accelerated the snagging process for construction managers.
Read moreA secure chat and calling app for frontline workers, built for CoCentric's Connect platform — messaging, voice and video, and a white-label design system that adapts to every organisation.
Read moreA running app for a UK running company — a cross-platform app that helps runners discover thousands of verified routes across Britain, race them on demand and track every run.
Read moreOne team, one policy for this list: name what we've shipped with, name what we work with, and never blur the two.
Bonsai's wealth-planning app ships from one React Native codebase — our default for cross-platform mobile.
We've built production web apps with React — dashboards and consoles where the interface does real work.
NicheCom's iPad app went native to drive laser-measuring hardware — that's the bar for native, and we build to it in Swift and work in Kotlin.
We work with Flutter where a project or team leans that way — the cross-platform decision matters more than the framework brand.
Backends are Django and Python — Go Quest's platform and Baandy's home-swap app both run on Django we shipped.
Shipped products run on all three — chosen per product, and still operated by us after launch.
We've shipped subscription billing on Stripe and Stripe Connect — products that take money from day one.
Design and engineering share one Figma-to-code path — what's tested with users is what ships.
This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.
Real reviews from clients we have delivered for, on Clutch and elsewhere.
The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.
Their flexibility and focus on quality were outstanding.
Marcelo has been wonderful throughout the process and we are very happy.
Absolutely FANTASTIC. This is very much what I had in mind. We're very pleased with your team, thank you all very much.

Everything from first designs to a product live in users' hands: UX and UI design, prototypes, web, mobile and SaaS builds, and the integrations that connect them to the systems you already run. It stops where our other solutions start — working out whether to build at all sits under strategy & validation, and long-run hosting, DevOps and support sit under infrastructure & support. The same team carries a product across all three, so nothing is lost in handover.
If the idea is still unproven, start with the prototype: from £5,000 and two to four weeks, you get a clickable, testable first version with the core flows working — ready to put in front of users and investors, and yours to build on with any team. If the product is already validated, the app build tier — from £15,000, taking a design through to the app stores — is the straighter path. Either way, scope and price are fixed and agreed before work starts.
Included. UX and UI design is one of the services inside this solution, done by the same London team that writes the code — design and engineering share one Figma-to-code path, so what gets designed is what gets built, with no translation loss between a design agency and a dev shop. And the design files are yours to keep, so even if you later took the build elsewhere, none of the work would be wasted.
You don't have to pick. Describe what the product should do and who it's for, and we'll map that to the right services in the first conversation — MVP versus full build, web versus native mobile, off-the-shelf versus custom software are delivery decisions, not homework for you. The scoping ends in one fixed quote covering whatever combination the product actually needs, and we'll say plainly if part of it isn't worth building yet.
Your call, but we're built to stay. The products we ship run on AWS, Google Cloud and Firebase infrastructure we still operate for clients month to month, and ongoing maintenance and support typically starts from £400 per month. Because the code and IP are yours outright once delivered and paid for, you can equally take the product in-house or to another team — there's no lock-in holding you here.
Part of the build. AI features ship inside our products on models we've already shipped with in client work, and this solution includes intelligent document processing — invoices, contracts and forms read, checked and filed by AI — alongside quoting and onboarding automation. Where AI is the point of the project rather than a feature of the product — automating a whole workflow, or AI agents working inside the systems you already run — that's our AI & automation solution, delivered by the same team.
A small, experienced team of designers, engineers and problem-solvers working closely with you from first idea to final delivery.
