Turn Your App Idea Into a Real-World Tool.
At iSonic Digital, we’re specialists—not generalists.
We design and develop custom mobile apps and web applications that are built to solve problems, improve performance, and scale with your business. Whether you need a customer-facing app, a streamlined staff portal, or an integrated digital tool, our Brisbane-based team works with you from concept to launch—creating tailored solutions that connect seamlessly with your systems and deliver measurable results. No one-size-fits-all. Just powerful, purposeful apps—built to work.
We build custom web and mobile apps tailored to your business needs from the ground up. Whether you need a customer portal, a staff dashboard, a booking system, or a mobile app that brings your service into your customer’s pocket—we’ve got you covered. We specialise in creating digital tools that aren’t just beautiful, but functional, scalable, and intuitive. Every app we build is designed with both front-end users and internal teams in mind, to make everyday processes faster, easier, and more enjoyable.
Great question—and the short answer is: both! We offer native mobile app development (iOS and Android) as well as responsive web app solutions. Native apps are perfect for functionality that relies on mobile device features (like push notifications or GPS), while web apps are fantastic for cross-platform accessibility—great for internal systems, customer portals, and management dashboards. We’ll help you decide what’s best based on your goals, budget, and user needs.
The timeline can vary depending on the complexity of the app. Our process includes discovery workshops, wireframing, UI/UX design, development, testing, and deployment. We also account for post-launch optimisation. If you have a tight deadline or need to break the project into phases, we’ll work with you to create a timeline that suits your priorities.
Absolutely! You don’t need to come to us with all the answers—we’re here to help define the solution. Many of our clients approach us with an idea or a challenge they want to solve, and we help them shape it into a user-focused app or platform. We start with a discovery session to unpack your goals, user needs, and any existing workflows. From there, we can map out a technical and creative direction that aligns with your vision and business objectives.
Yes, we do! Launching your app is only the beginning. We offer ongoing support, maintenance, and updates to keep your app secure, optimised, and evolving with your business. Whether it’s adding new features, improving speed, or refining UX based on real user feedback—we’re in it for the long haul. And because we built your app in-house, we know it inside-out, making us the perfect partner for ongoing growth and support.
Yes! Integration is a big part of what we do. Whether you’re using a CRM, ERP, eCommerce platform, or payment gateway—we can build apps that seamlessly talk to your existing systems. We’ve worked with everything from MYOB to Stripe, Salesforce, Xero, and even custom-built tools. Our goal is to connect the dots and make your tech ecosystem work better together.
Costs vary depending on scope, features, and whether you’re building a web app, native app, or hybrid of both. Some smaller web-based portals may start from $20k–$30k, while more complex app builds can range much higher. The best way to get a clear idea is to book a chat with our team—we’ll work through your goals, functionality requirements, and provide a detailed proposal with timelines and costs.
