Custom Mobile and Web App Development

Modern businesses need more than just software they need smart, scalable digital tools tailored to their workflows, customers, and growth goals. Our service offers end-to-end design, development, and implementation of customised mobile and web-based apps for businesses that are ready to innovate.


Build Apps That Power Your Business, Not Just Your Processes

From internal platforms that automate manual tasks to customer-facing mobile apps that enhance engagement and experience, we specialise in designing, developing and implementing fully customised mobile and web-based applications for businesses of all sizes.

Unlike off-the-shelf tools, our apps are purpose-built around your strategy, operations, and customer journey. They scale with you. They integrate where you need. They solve your problems not someone else’s.


What We Deliver

Our design, development and implementation process delivers apps that are technically robust, user-centric, and commercially viable. You’ll get more than just a product you’ll get a strategic digital asset.

1. Discovery & Scoping

We start by understanding what your business needs not just technically, but strategically.

  • Identify bottlenecks, inefficiencies, or opportunities for digitisation
  • Clarify business goals, user roles, security, and integration needs
  • Explore whether a mobile app, a web-based app, or a hybrid solution fits best
  • Scope features, outcomes, and ROI potential

Our collaborative scoping process means the final product fits like a glove.

2. User-Centric Design

Great design is invisible, it just works. We blend UX/UI principles with your brand and workflow needs to ensure adoption and usability.

  • Wireframes and prototypes for rapid feedback
  • Mobile-responsive web app layouts or dedicated mobile UI/UX
  • Custom design systems that grow with your business

We focus on intuitive interfaces that drive real usage, whether it’s for internal teams or external customers.

3. Full-Stack Development

Using modern technologies and frameworks, we develop secure, scalable custom applications tailored to your use case.

  • Agile, iterative delivery with regular progress checkpoints
  • Front-end and back-end development for mobile or web-based apps
  • Seamless integration with CRMs, ERPs, databases, or third-party APIs
  • Security and compliance baked in from day one

We’re technology-agnostic and build using what’s right for your goals whether that’s React, Flutter, Node.js, Firebase, or other industry-leading stacks.

4. Implementation & Deployment

The launch of your custom app is only the beginning. We handle everything from infrastructure setup to post-deployment support.

  • Cloud deployment and hosting strategy
  • Beta testing with user feedback loops
  • Training for staff and admins
  • Ongoing performance monitoring and optimisation

Apps are implemented with minimal disruption and maximum long-term value.

What Makes Josty Different

Unlike pure development shops, we’re business-first. Our team brings strategy, operations, and user experience thinking into the heart of the build process. That means your app won’t just “work” it will work for your business.

  • Strategic grounding: Every feature maps to a clear business outcome.
  • Design + delivery: UX is baked in, not bolted on.
  • Scalable approach: We don’t just build - we plan for growth.
  • NZ-based, globally ready: Work with a local partner who understands regional market needs, compliance, and expectations.

We don’t just build custom apps. We help you create smart digital tools that move the needle.
