Mobile App Design Service

As a premier app design agency, we’re totally passionate about transforming ideas into engaging mobile experiences. Based in the heart of London, our team combines their creativity, technical expertise, and a deep understanding of user behaviour to deliver outstanding mobile app designs.

We pride ourselves as being a leading app design agency in London, and of our ability to craft custom solutions that meet the unique needs of each client. We achieve this due to our client-centric approach, where we prioritise your vision and feedback throughout the design process to ensure that the final product aligns perfectly with your goals.

We’re also an expert team of designers with years of experience who have a finger on the pulse of the latest design trends and technologies. Our comprehensive services begin from initial research to the final delivery, and our full-service approach covers every aspect of the design process, ensuring a seamless and efficient experience.

So why not choose us for an innovative, user-focused design that will set your mobile app apart from the competition?

Our Comprehensive Mobile App Design Process

The mobile app design process we have set in place is meticulously crafted to ensure that every app we create is not only visually stunning but also user-friendly and functional. Our approach is designed to focus on both aesthetics and user experience to deliver an app that, at a base level, meets business goals and delights your users.

Discovery Phase

The discovery phase is where we lay the foundation for your mobile app design. We start by conducting in-depth consultations to understand your business objectives, target audience, and specific requirements. Our team performs market research and user analysis to gather insights that inform the design process. By understanding your needs and goals, we ensure that our mobile app design services are perfectly aligned with your vision.

Design Phase

The design phase is where we bring your concept to life, through user interface design that blends creativity and intuition, developing interactive prototypes, and the conducting of rigorous user testing that will refine the initial design for the best user experience the app can offer.

The focus is always on how we can create a seamless and engaging user experience, something that truly gets the job done while looking spectacular.

Delivery Phase

After providing you with all the final design files and necessary assets all ready for development, our team will then provide detailed documentation and support so you have the smoothest transition possible. The work doesn’t when the design has been handed over, we remain available for any post-design support you might need, so your app continues to work at its best; we’re here to support you every step of the way.

Why Our App Design Agency Stands Out

We know we stand out because of the way we centre our clients in our projects. For business owners, or anyone seeking an app design agency, choosing the right one is the most crucial step you can take to influence its user experience, functionality and overall market reaction.

We stand out because of our approach to app design. It is highly collaborative and client-centric, with a commitment to deeply understand your vision, target audience and market objectives. Together, with your insights and our expertise, we ensure that each and every design decision is made with your brand identity in mind, and that it meets the goal of resonating with your users.

For us, a project is only well-done and completed if the client is completely satisfied. We’re transparent. We communicate. We provide regular updates and post-launch support so deployment day runs smoothly and optimally. Our goal as an app design agency is not just about meeting your expectations, but about becoming your trusted partner in achieving long-term app success.

What else do we bring to the app design table?

The client-centric approach is the best way to meet the specific requirements of each of our projects, from initial consultation, to final design delivery, we work closely with you to understand your vision and incorporate any feedback at every stage. Our mobile app design services are designed to provide a personalised experience that prioritises your goals and preferences, putting the “U” back in “UX”.

Tom and Bruce at Nautilus were a fantastic help to our team as we navigated the first stages of setting up out podcast. They kept us up to date and were very generous with their time, providing many opportunities to comment on the design of our cover art and logo to ensure we achieved our vision.

I couldn’t be happier with my experience with Nautilus Marketing, especially working with Tom. I needed some support with my website and he was incredible from the very beginning. He took the time to properly understand what I was trying to achieve, then worked tirelessly to get everything in place and make sure I was confident about what needed to be done.

What really impressed me was how much Tom supported me in understanding things from a marketing perspective not just fixing the website, but helping me see how all the pieces fit together to get results. He explained everything so clearly and made sure that, when the project was handed back to me, I felt in control and knew exactly what to do next.

The communication was excellent throughout I always felt listened to and supported, and nothing was ever too much trouble. What really stood out was Tom’s energy and enthusiasm for my success; it’s infectious and made the whole process enjoyable as well as productive.

I was super pleased with the result and the improvements to my site have already made a big difference. This is a company that genuinely cares about getting the best outcome for you. I’ll definitely be using them again and recommending them to others without hesitation. An all-round fantastic business!

Working with Nautilus Marketing has been an incredible experience from start to finish.

From the very beginning, Tom, Jake, and Bruce made me feel fully supported. Not just as a client, but as someone whose vision truly mattered. Their communication is always clear, timely, and human, and the attention to detail at every step is second to none.

Bruce in particular has been outstanding in managing the day-to-day process: super organized, responsive, and genuinely invested in bringing the best version of the project to life.

One of the biggest advantages of working with Nautilus is that they’re a full-service agency. That means you're covered from the very start: brand identity, logo, website, SEO and all the way to scaling with ads, link building, and beyond. It’s rare to find an agency that can stay with you through all these phases and keep the same high level of care and consistency.

If you're looking for a team that listens, executes flawlessly, and actually cares about making you happy! I couldn’t recommend Nautilus more.

We used Nautilus for our SEO, and started with the Setup Package. They were really easy to work with, professional and everything was done to a timely manner. It was all explained and easy to understand, so I highly recommend the Nerds at Nautilus! Looking forward to using them again in the future. 🙌🏼 - Taking The Pixels

After a meeting with Nautilus Marketing our Accounting firm very much realised we were scratching the surface with marketing and needed to be brought into the 21st century. Tom and Jake were extremely knowledgeable and very helpful explaining in layman's terms how the Nautilus team can help us grow and what strategies would work for us. What you have done so far has been amazing and very much given us the confidence to agree a long term marketing plan with you. Very much look forward to working with you in 2024 and beyond.

We tasked Nautilus with a new logo and website design for our company, which they excelled with. Bruce was in touch with every step to ensure we were up to date with progress and happy with the results. The new logo looks amazing and with the new website going online this week we are happy we chose the right company to look after this for us.
Both logo and website came in on time and on budget. We would recommend Nautilus to anyone who needs any form of digital marketing. With both Tom and Bruce, you will be in safe hands.

I had a fantastic experience with Nautilus Marketing. Bruce and the team did a fantastic job.

No request was to big either, and Bruce and the team were excellent at keeping me updated throughout the entire process.

Towards the end of the project we experienced some minor technical challenges. However, the way Bruce kept me updated during this situation and how quickly the team were able to resolve made the experience reassuring.

I would definitely recommend Nautilus.
