Extend your product cross-platform

We have experience in building apps for multiple industries, including SaaS, sports, education, 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 Ireland-based custom photo printing and wall art business, selling canvas prints, framed artwork, photo collages, wood blocks, and travel posters, all produced in house. Online sales are the primary revenue channel, running on a bespoke Shopify site that already handled customisation, checkout, payments, and order management competently. As repeat custom and mobile traffic grew, the gap was not capability. It was that mobile customers wanted a faster way to reorder.
Hear what clients say about us.
Our mobile app clients trust us for results, reliable communication, and on-time delivery. Here's what they say.
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.

UX-First mobile software design & development.
UX is not about having an app look good.
Our UX-centered app development approach results in less work down the road, as the app is made backed with research and with end-users in mind.
User-friendliness in an app is the most important factor for adoption. An app made with UX at the forefront in every stage of development will give you a quick market penetration and a fast-growing user base.
Our design decisions are validated early in the process (and are shared with you). This ensures we're on the same page and on the right track to make a great app.
Our mobile software development philosophy.
At Exline Labs, we do app development differently from most agencies.
Our approach is centred around user experience. We put the users of your app, the reasons they use it, and the needs of your business into focus.
UX is a way of thinking for us, not a phase. We take UX learnings and principles into every part of our mobile app making.
Our design and development teams work in tandem on all development projects, leading to a cohesive, seamless process and apps.
Our Mobile App Development Process.
01
WEEK 1Discovery & understanding users
Let's start with what the data says
Once we're do a discovery call, pencilling the project you need, we start with interviews with actual users in your target group and team members. We also conduct audits and reviews of analytics if you have an existing app or a platform.
02
WEEK 2-4UX design & flows
We build with your UX goals in mind
We organise the content and the mapping of tasks. This is done based on the information we found during the research phase.
03
WEEK 5-7Development
Design and dev come together
We hand-code the backend of the app with the UX team's inputs from previous stages. Our mobile app developers closely collaborate with the UX team at all times.
04
WEEK 8Testing & launch
Ready to go!!!
We test the prototype with handpicked target users and track how the app performs before launch.
05
Iteration & improvement
Continuous refinement and better versions
We keep supporting you with optimisations and reiterations once the mobile app is released.
Technologies we use to build your mobile app.
We choose our tech stack based on what works best for your mobile app, rather than what's trendy and hot.
Languages
Frameworks
Database
Platforms
Advanced capabilities we build into your app.
Machine Learning
AI apps made by us will learn from user behaviour, providing improved user experiences and better personalisation each passing day.

Work with Exline Labs to develop cloud-native mobile apps to scale fast and securely. Our mobile app development company can partner with you take your startup to the next stage.

Before your discovery call, we research your idea and come prepared with findings, not just questions.
