Building Successful Apps for Millions of Users
Whether you are an enterprise, startup, or a global organisation, building something new or improving an existing app, we help you design and build mobile solutions that are simple, reliable, and easy to use.
Apps That Are Easy to Use and Built to Last
Our mobile development teams combine technical know-how with thoughtful design to make sure your app works well – for your users and your business. With years of experience in mobile development, our in-house teams make sure your time and investment are optimized at every step of the app’s development – from planning and architecture to testing and long-term support.
Our services
Consultation before development
We begin by understanding what you need for your business and app – gathering insights, identifying challenges, and defining goals that matter most to you. This gives us a solid foundation to design the right solution from day one.
Scalable mobile app architecture & ERP/CRM integration
We design mobile app architecture that’s built to grow with you – scalable, maintainable, and ready for whatever comes next. Whether it’s backend systems, cloud infrastructure, or third-party APIs, we make sure your app integrates smoothly with the rest of your ecosystem.
User-centered design
We focus on real users and real use cases – desining intuitive interfaces that are easy to navigate, aligned with global UX best practices, and built to support meaningful interactions.
Full-cycle development
From your first idea to launch (and beyond), our team is with you at every step of the process, making sure everything stays on track. We work in agile iterations to build, test, and refine – so your app is always moving forward with clarity and speed.
Quality & security assurance
We provide mobile app QA and security testing across devices, platforms, edge cases and compliance scenarios – ensuring your app is stable, secure, and ready for real-world use. Our QA practices cover everything from functionality and performance to usability, accessibility, and built-in security measures that protect your users and data.
Long-term mobile app support & maintenance services
Our work doesn’t stop at launch. We offer long-term support, updates, and maintenance to keep your app secure, compatible with the latest platforms, and always in line with your growing needs.
Mobile app audit
We review your existing mobile app to uncover hidden issues, outdated code, and performance bottlenecks that could limit its value. Our mobile app audit service gives you a clear picture of your app’s current state, highlighting opportunities to improve speed, stability, security, and scalability – so you can move forward with confidence.
Tools & frameworks we use
We work with a broad range of proven technologies to build mobile apps that are reliable, scalable, and tailored to your environment. From native and cross-platform development to backend integration and API design, we select the right stack for your goals – with a focus on maintainability, security, and long-term value.
It’s not just what we do – it’s how we work
We focus on getting things done in a way that’s efficient, reliable, and makes sense for your team. At Helmes, we’ve built teams that have worked together for years – people who know the tools, the process, and each other. Because of that, we’re able to deliver real productivity. And that means time and cost savings for you.

We call it The Helmes Way. For decades, we’ve worked to perfect it.
