Custom App design and development
App design & development for small businesses.
Our app design and development services are built specifically for small to medium-sized businesses with big ideas, whether you are launching a new product, building a digital tool, or turning a fresh business concept into reality. We specialise in creating lightweight, scalable apps that bring your vision to life, without the custom agency price tag.
Many of our clients come to us with new ideas or business inventions that need the right technical foundation to succeed. They have often outgrown DIY tools or struggled to find developers who understand both the creative and practical sides of building a product. Off the shelf platforms rarely offer the flexibility, user experience, or performance required to build something truly original.
That is where our approach comes in. We work closely with you to design and build custom apps that do exactly what your idea needs, no more, no less. With a focus on intuitive design, smart functionality, and long term maintainability, our apps are built to support your business now and evolve as your idea grows.

mohunky have built my website and my app: Biorhythms.Exercise.Nutrition Ltd. Completely new territory for me, they have been brilliantly supportive and patient while guiding me through the process from concept to delivery. I cannot recommend them highly enough, and I look forward to a great ongoing business relationship with them.
The stress free process.
Getting your app designed and built with mohunky is simple and stress free.
We know that starting an app project can feel overwhelming, especially if it’s your first time or if you have had a bad experience before. That’s why we guide you through the process step by step, handling the technical side so you can focus on what matters most: bringing your idea to life.
Whether you have a clear vision or just the beginnings of an idea, we work closely with you to shape it into something that feels right, and functions beautifully from day one.
Here is how we work:
We kick things off with a relaxed conversation to understand your idea, your goals, your audience, and how the app will fit into your business. Whether it is a product, tool, or internal system, we help you think through what it really needs to do.
We create a clear proposal that outlines exactly what we will deliver, features, tech stack, timelines, costs, and what we need from you. No jargon. No hidden extras. Just clarity from the start.
Next, we sketch out how your app will work, screen by screen, before moving into design. We focus on intuitive layouts, a friendly user experience, and a look that fits your brand.
Once the designs are approved, we build your app with performance, security, and scalability in mind. We test on different devices and make sure everything behaves as it should so there are no nasty surprises.
Before launch, we prepare a private beta version of the app and share it with a selected group of users via our internal testing platforms. This allows for real world feedback, early bug detection, and the opportunity to refine the experience based on how people actually use it.
We handle the full submission process for the Apple App Store (and Google Play, if needed), including preparing all the required assets, meeting store guidelines, and navigating the approval process. Once it is approved, your app goes live and is ready to use!
We show you how to manage your app content (if relevant), and we are always here for updates, improvements, and long term support as your app grows and evolves.

I personally just wanted to say a massive thank you for all the support and work you've done over the years, it's been a pleasure working with you!
Choosing mohunky for your App design & development.
What makes us different? We help bring your ideas to life without the stress.
Many of our clients come to us feeling stuck. They have an exciting idea but no clear path to make it real. Others have tried working with developers who overcomplicate things, overcharge, or simply do not deliver what was promised.
One of our clients came to us with a thoughtful and ambitious idea, to create a tool to help young teenagers track their mood and wellbeing in a way that felt safe, supportive, and engaging. Working closely with the team behind B.E.N-App, we designed and built a lightweight mobile app that makes it easy for young users to check in with themselves, reflect on their day, and build healthy emotional awareness over time. The project involved careful planning, sensitive design, and clear communication throughout. The final app is now being used in schools and support settings across the UK, and was recently nominated for a Wellbeing and mental health initiative award.
At mohunky, we do things differently. We keep things simple, honest, and built around you.
