TESTIMONIALS.
Real feedback from app founders and teams.
"44Degrees didn't just optimise our app; they helped transform our entire business. Going from just a handful of subscribers to over 74,450+ recurring active subscriptions, their holistic expertise, growth marketing and ongoing advice over the years has been second to none. They are true partners in our growth."
Heatley Gilmore
CEO, Camps Australia Wide Pty Ltd
"After years of testing different marketing approaches to cost-effectively grow Vampr's paying subscriber base, we knew our conversion performance could be materially better. 44Degrees challenged every assumption, rebuilt our subscription strategy, and delivered results beyond expectations. Their experience and evidence-based approach provided exactly the support the business needed"
Josh Simons
CEO at Vampr and Vinyl Group Pty Ltd
"What you did for us was truly amazing! Thank you so much for making the time and effort for us, we really appreciate it."
Dr Nikhil Povia
Founder and CEO, CancerAid
"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!"
Em & Josh
Founders, Hooked Up Pty Ltd
"Jarrah & Zinnia's strategy for Parpera was impressive. They met our targets in a competitive business finance category and achieved a 480% increase in our recurring subscription revenue during our first 3-month campaign - a testament to their comprehensive product strategy, ASO and acquisition expertise."
Daniel Cannizzaro
CEO, Parpera
"Above and beyond. I just checked on iTunes and our app has hit Number 1 in Education and Number 7 in the Top 100 apps in iTunes!!! Awesome result and extremely happy."
Adam Bridle
Director, Platinum Driving Tuition
"44Degrees was instrumental in bringing SmartTasker from concept to a thriving platform in just a few months from launch. Their end-to-end expertise in app design, onboarding optimisation, targeted user acquisition campaigns and overall go-to-market strategy has been excellent."
Ahmad Dabboussi
Founder & CEO, SmartTasker
"44Degrees's work on Old Macdonald Sing & Play was incredible. We saw a 366% increase in organic downloads and an incredible 709% boost in in-app purchase conversions, achieving a Top 10 'Kids under 5' ranking in Australia and the UK, plus a No.3 'Highest grossing apps' rank for Kids apps under 5yrs, and No.5 Highest grossing 'Entertainment' app. Thank you!"
Paul Kuske
Founder, ChocChipApps
"Jarrah and the 44Degrees team have been a valuable partner for Kmart's app growth across Australia and New Zealand. Their ASO work delivered measurable keyword ranking improvements across the board - we had a 35% improvement in keyword ranking volume within the first 59 days, with gains on high-competition shopping keywords, and over time achieved strong rankings across more than 590 relevant keywords. The Apple Ads campaigns were set up and managed with real attention to detail too, ensuring we were acquiring genuinely new users within our target CPI - not just reinstallers or assisted installs. Jarrah is proactive, transparent with data, and always thoughtful about what to optimise and when. We highly recommend."
Karlien McLeod
Digital & Growth Leader, Kmart Australia Limited
"We brought 44Degrees in to help grow PainChek Infant's consumer user base, but what we got went well beyond campaign management. Jarrah and the team quickly identified critical gaps in our app's onboarding and subscription flow, and their UI/UX recommendations led to an 11x improvement in our install-to-trial conversion rate.
On the paid acquisition side, their Meta and Apple Search Ads campaigns delivered the strongest in-app subscription conversion activity we'd seen to date - significantly outperforming previous agency efforts.
But more importantly, they brought genuine strategic thinking to every conversation. From product positioning to messaging to understanding the nuances of marketing a sensitive health-tech app to parents, they challenged our assumptions constructively and backed everything with data.
I'd recommend 44Degrees to any app company looking for a partner that goes deeper than just running ads."

LOCALLY BASED, GLOBALLY EXPERIENCED.
Serving Perth founders from Wanaka, New Zealand.
While we're based in Wanaka, we work closely with Perth founders across the city's growing tech ecosystem - from the West Perth fintech cluster to the CBD startup community and the mining-tech focus serving Rio Tinto, Fortescue and BHP. Perth's timezone advantage with Asia, combined with the rise of resources-tech and remote-friendly SaaS founders, creates a different but equally ambitious opportunity set.
Perth has a unique founder base - shaped by Western Australia's resources economy, its proximity to Asian markets, and its remote-first culture. 44Degrees has worked with founders building everything from local-market apps to globally-scaled subscription products - we understand both paths.

App Development in Perth - FAQs
App development costs in Perth follow Australia-wide market rates: typically AUD $25,000 to $500,000+ depending on scope and complexity. Industry MVP-level apps usually land between AUD $100,000-$150,000+.
At 44Degrees, we front-load validation and design before development begins. Perth clients who complete our validation process typically launch a pre-validated MVP for AUD $45,000-$85,000 total - that's how our clients typically save 70-90% vs traditional Perth-based agencies. We only build what's proven to work.
Our 4-phase, validation-first process typically takes 3-5 months from idea to successful MVP launch - and protects your investment with GO/PIVOT/NO-GO decision gates at every stage:
- Phase 1 - Market Intelligence & Validation: 2 weeks
- Phase 2 - Landing Page Validation Campaign: 2-4 weeks
- Phase 3 - End-to-end MVP Design: 2 weeks
- Phase 4 - Rapid MVP Development: 6-8 weeks
Traditional "build first" agencies typically take 6-12+ months of blind development. Because we validate first, you're not wasting months building something that's doomed to fail.
No. Anyone can type a prompt into ChatGPT and get a surface-level opinion on an app idea - but that's not validation. Our process uses proprietary tools we've built over 15+ years that scrape real market data, analyse competitor ecosystems, and model unit economics based on actual campaign performance from thousands of campaigns we've personally run. We then stress-test your acquisition assumptions with real ad spend and layer expert human analysis on top. The output isn't an opinion - it's a definitive GO, PIVOT or NO-GO backed by real numbers.
We work across the full spectrum: B2B, consumer apps (iOS & Android), SaaS platforms, marketplace apps, subscription-based products, and enterprise mobile solutions. Our sweet spot is apps with a business model - whether that's subscriptions, transactions, or user growth. We've helped apps across fitness, education, social networking, travel, healthcare, and more.
