Mobile and web apps that feel intuitive, engaging and effortless to use

Not just another app interface. Not another cluttered user experience.

Your app should do more than function, it should guide users naturally, create confidence instantly and make every interaction feel seamless. We create bespoke app experiences built around real users, real behaviours and real business goals.

Whether you’re launching a startup product, redesigning an existing platform or building a new digital experience from the ground up, we design apps that people genuinely enjoy using.

The thinking behind every app we build

Discovery & Research

Every project starts with understanding your business, audience and goals - through workshops, planning and UX research.

Mapping the User Experience

Before visual design begins, we craft the user experience through wireframes to create intuitive journeys, clear navigation and conversion focused experiences.

Bespoke Visual Design

We create clean, modern design systems that elevate your brand while prioritising usability and accessibility.

Build

We work to ensure designs transition smoothly into production, creating scalable systems, reusable components and structured design patterns that support future product growth.

Optimising your Content

We’ll help populate your app with content that’s on-brand, SEO-friendly, and designed to improve your visibility in search.

Supporting your Growth

Launch is only the beginning. We'll be here to help your app evolve over time, and support future content, campaigns and digital expansion.

Sectors we serve

Accessibility compliance, GDPR and security built in from day one

Public sector websites need to make complex information and essential services simple to access. We create clear, accessible user journeys with intuitive navigation, powerful search and secure functionality, backed by flexible CMS tools that make content easy to manage and keep up to date.

Let’s build something impossible to ignore

Whether you’re building a startup product, redesigning an existing platform or creating something entirely new, we can help design an app experience people genuinely want to come back to.

What our clients say

Green17 have been a trusted partner throughout the development and launch of the Staffline Recruitment App and wider digital transformation projects. The team took the time to thoroughly understand our business, our users and the scale of our operation across Ireland. The final product reflects our brand brilliantly while delivering a seamless, user-friendly experience for job seekers, workers and clients. What really set Green17 apart was their collaborative approach, responsiveness and ability to turn ambitious ideas into practical, high-performing digital solutions. I would highly recommend Green17 to any organisation looking for an innovative team to support their digital transformation journey.
