Real mobile app screens
Shipped product, not a mock-up
Appalanche designs and builds custom mobile apps for Australian businesses. One senior developer takes your product from scope and interface design through development, backend integrations and store submission, with a fixed quote in AUD before the work begins.
Below are production screens from Limbo, a group-trip planner Appalanche designed and built for iOS and Android. The work covered the mobile app, backend, integrations and store submission.






Limbo is live on iOS and Android. See how it was built.

What you get
A small senior studio, not an agency pipeline. Here's what that means for your project.
A quote in two business days
One fixed price, in AUD, with the scope written down. If the scope doesn't change, neither does the price.
Senior build, no juniors
Your project is built by the founder, the same developer behind Limbo and My Love Your Love. Nothing gets handed down the chain.
Weekly demos
See a working build every week, not a status report, on calls that fit your Australian business day.
You own the IP
The repository and project accounts can be under your control. Ownership of the custom code, designs and documentation transfers on full payment.

Questions, answered
How much does an app cost?
It depends on what you're building. A marketing website, a web platform, and a two-platform mobile app with its own backend are very different projects. Anyone who quotes a number before understanding the scope is guessing. That's why we scope first: tell us what you need and you'll get one fixed price in AUD within two business days, and it only changes if the scope does.
How long will my project take?
Timelines depend on scope and current availability, so your quote includes a proposed start date and written delivery timeline alongside the price. Once the build begins, you see a working demo every week, so there's never a long silence.
Who owns the code?
On full payment, ownership of the custom code, designs and documentation created specifically for your engagement transfers to you. The source repository and project accounts can be set up under your control during delivery. Pre-existing tools and open-source components remain under their existing ownership and licences.
Do you work with businesses outside NSW?
Yes, we work with clients across all of Australia, fully remote. We're based in New South Wales and collaborate in Australian time zones, so calls and demos happen during your business day.
