WHY WORK WITH US.
Bring your app idea to life with the App UI/UX Design specialists.
We're at the forefront of UX
Development teams aren't designers. They excel at coding but lack expertise in app strategy and cutting-edge UI/UX. Our 15+ years of expertise ensures we design what your app actually needs, no cookie cutter templates, overlooked functionality or UX shortcuts.
We save you dev time & cost.
Avoid delays, rework and overspend during development. We make sure your project is accurately scoped and designed before development starts. An accurate design = accurate development costs & timelines. No surprises later on!
We'll launch your app faster.
Get your app idea to market quicker by preparing properly. The right design preparation speeds development, validates your idea quickly, and ensures a smooth, high-impact launch so you can seize opportunities and stay ahead of competitors.
We'll reduce your risk.
Our rigorous upfront planning and validation removes common pitfalls and lowers your project's risk; giving you confidence and a clear roadmap to success.
We deliver clear processes & deliverables.
Our proven process delivers results with clear timelines, transparent billing, and a structured approach that keeps you in control at every step.
We actually give a s**t
Unlike other agencies or inexperienced in-house staff, we care about what is actually required to maximise your chances of success and growth.

TESTIMONIALS.
Real feedback from teams and founders who've worked with us.
"We came to 44degrees with an app that wasn't ready for launch. While we had a solid understanding of marketing, apps were a completely different world for us.
They helped us optimise our signup flow, onboarding, and paywall, and guided us through the app-specific strategy we were missing, particularly ASO and paid acquisition for apps. Their support helped us understand how growth actually works in the app ecosystem, not just what to do.
When we launched, a combination of our organic momentum and their ASO and ad support took us to #3 in Sports on Google Play and #21 on the App Store in Australia in the first month. We reached profitability (return on ad spend) within 20 days, which was a huge milestone for us.
What made the biggest difference wasn't just the results; it was the guidance. At every stage, we knew what to focus on, what actually mattered, and how to move forward without constantly second-guessing ourselves. Their approach has been thoughtful, thorough, and genuinely supportive. We are so grateful to have found them!"

HOW IT WORKS.
App Design FAQs
App design in Australia typically costs $25,000 to $100,000+ depending on scope and complexity, and mostly based on assumptions.
Here's what we see across our projects:
- MVP design with real-user validation: $5000–$25,000 AUD — Real market testing & validation, Core MPV features defined, custom components, high-fidelity UI and complete UX prototyping
- Complex/enterprise-level App design: $25,000–$50,000+ — data-driven UX, design systems, multiple user types, extensive user testing, analytics, and refinement
Why our costs are lower: We don't design anything until we've validated the idea first. Our clients typically save 70–90% on total project costs because we only design what's proven — not a 47-screen wishlist that gets cut in half after launch.
We've seen founders spend $30K+ on beautiful designs for features their users never touched. Validation isn't a delay — it's insurance, heavily reduces your long term costs, and speeds up your path to success.
Our app design service includes comprehensive market & user research, competitive analysis, real market demand testing, user flow mapping, wireframing, high-fidelity UI design, interactive prototyping, design system creation, and developer handoff documentation. We deliver everything required to build your app and maximise your chances of success.
We work with both. We help startups (Seed to Series A) validate ideas and design MVPs, and we help established app companies ($2-200M ARR) optimise their UX and scale their user base. Our process adapts to your stage and needs.
Specialist app design agencies bring deep expertise in SaaS and mobile app business strategy, UX patterns, platform guidelines, and user behavior. We understand what's required to make an app successful and bake everything we do in to your design from day one, whether it be business model strategy, growth marketing, or user retention expertise, we deliver super high quality apps and nuance that generic design agencies miss, ensuring your app has a high probability of success.
After design completion, we can help you with development partnerships, launch strategy, user testing, and ongoing optimization. We provide a complete roadmap from design to market success, ensuring your app reaches its full potential.
While we specialize in app strategy, design and marketing, we work with trusted development partners and can manage the entire development process for you. We ensure seamless handoff from design to development and maintain quality control throughout the build process.
