Mobile app development company for UK startups and growing businesses.
Who we build mobile apps for.
Validate your startup idea
A focused MVP app gets your idea in front of real customers before you invest in the full build.
Take your processes digital
An app your team and customers will actually use, because it's designed around them first.
Take your product cross-platform
Move a web product to mobile, or bring an app to iOS or Android, from one codebase.
SaaS, sport, ecommerce, education, logistics and more.
Mobile apps we've built.
Extending a Shopify store into a mobile app that lifted weekly orders by 60%
TheCanvasWorks.ie is an Irish custom photo printing business with its own Shopify store. The store worked well. What mobile customers wanted was a faster way to reorder, so we built them an app for it.
Hear what clients say about us.
Clients stay with us for the results, the communication and work that arrives on time.
Germany
Communication was always followed up and deliveries were on time. They were always available for additional help and support. This is not what I experienced with the agency I used before — with Exline I always knew exactly where the project stood.

App scaling and optimisation
Faster performance and new features for apps that are already live and ready to grow.
UX-first mobile app design and development.
Good UX is about more than how the app looks.
Research up front means less rework later, and keeps the people using the app in focus.
An app that's easy to use gets adopted, and that's what grows a product.
We test design decisions early and share them with you as we go.
Our mobile software development philosophy.
At Exline Labs, we do app development differently from most agencies.
Most mobile teams start with features. We start with the people who'll use the app.
We look at who they are, why they'd open the app and what your business needs from it. Design and development work side by side on every project, so what gets built is what was designed, and it works for the people using it.
Our mobile app development process.
01
DiscoverDiscovery and understanding users
Let's start with what the data says.
A discovery call, interviews with your users and team, and an audit or analytics review if you already have an app.
02
DesignUX design and flows
We build with your UX goals in mind.
We organise the content and map each task based on what the research showed.
03
BuildDevelopment
Design and development come together.
Our engineers build the app in close step with the designers.
04
LaunchTesting and launch
Ready for the App Store and Google Play.
We test with real users and set up tracking before launch.
05
ImproveIteration and improvement
After launch, we keep refining the app based on how people use it.
Technologies we use to build your mobile app.
We choose the stack for your app, not for what's fashionable.
Languages
Frameworks
Databases
Platforms
Cloud
Hosting
Advanced capabilities we build into your app.
Machine learning
Apps that learn from how people use them and personalise the experience.
Cloud
Cloud-native apps that scale securely as you grow.
Data analytics
Our mobile app development team builds in analytics, so you can see what users do and decide what to build next.
Artificial intelligence
Chatbots, image recognition and voice assistants, where they make the app better.
Let us know your need.
Before your discovery call, we research your idea and come prepared with findings, not just questions.
Mobile app development frequently asked questions.
Do you develop for both Android and iOS?
Yes. We build native iOS and Android apps, and cross-platform apps in Flutter or React Native. We're a Flutter app development company at heart, and for most startups we recommend one codebase, because it's faster to build and easier to maintain.
Can you build AI into a mobile app?
Yes. Predictive search, smart analytics, recommendations and chatbots are all things we've built.
Do you help with App Store and Google Play launch?
Yes. We handle the submissions, compliance and security checks, and support you after launch.
Which industries do you work with?
Sport, healthcare, SaaS, logistics and education, for clients in the UK, Germany, France, Ireland and New Zealand.
What makes Exline Labs different?
We combine UX research, design and engineering in one in-house team. The people who design your app are the people who build it.
How long will it take?
A focused MVP app takes 1 to 6 weeks. A fuller app with more features takes longer, and your proposal confirms the timeline before work starts.
Do you work UK hours?
Yes. Our team is in Sri Lanka and is online 8am to 5pm UK time, with daily updates in your channels.
How will we communicate?
We start with a video kickoff, then stay in touch by email, Slack or WhatsApp, whichever suits you.
How much will it cost?
A focused mobile MVP starts from £10,000. Larger apps are quoted after a free consultation, and you get a fixed, milestone-based proposal before any work starts. Our guide to mobile app development costs in the UK shows typical budgets.
Who owns the app and the IP?
You do. All work is done on a work-for-hire basis, and we make no claim on your app.
Do you offer maintenance?
Yes, on a monthly, annual or bi-annual retainer. That covers fixes, updates for new iOS and Android versions, and hosting for your app's back end on UK servers, with backups and monitoring. If you'd rather run it on your own AWS, Azure or other cloud account, we'll set it up and deploy it there.
