When it comes to out-sourcing and partnering with a technology vendor, Rocket Lab is top of mind. 
Julien, Jen and the team are incredibly detailed and thorough whenever they’re engaged in a project. And, they do so at velocity. For Superloop, they have delivered some of the biggest, and highest profile projects that we have done in the last 12 months. I look forward to our continued relationship and what we can continue to achieve in the future.

We had the pleasure of working with Rocket Lab team for the development and launch of the Lasoo.com.au website and app. With a tight launch timeline to comply with, Julien assigned 4 talented front end engineers with the appropriate skillsets to help us get both the app and website across the finish line on time. The guys worked together very well with our internal resources and blended into our process seamlessly. We were very impressed with the level of skill from each of the engineers, while their teamwork, professionalism and dedication was exceptional.

Rocket Lab helped digitally transform our business by moving from our initial MVP website/platform built in India to a scalable website and architecture built on the latest JS tech stack. Our business has hundreds of suppliers and thousands of customers so we needed a highly robust structure and that’s exactly what was delivered by Julien, Jen and the RL development team. The bonus was that they were great to work with! We strongly recommend them for your web & app development needs.

FAQs

How much does mobile app development cost?
Green Triangle

The cost of mobile app development in Australia will vary based on your requirements.

The average cost to build a mobile app in Australia is anywhere from $200,000 to $400,000. The exact cost will vary based on the design, features, integrations and backend capabilities. The location of the team will also impact costs. The salaries of app developers in Australia are at an all time high. This explains why most local companies like ourselves will be more expensive than the competition. Make sure to check where the software development is located as it is not uncommon to see companies charging local rate when the team is actually overseas.

Before getting a quote to build a mobile app, we strongly recommend going through a discovery phase where the wireframes, user stories and overall UX & UI design are defined clearly.

How long does it take to build a mobile or web application?

Because every project is different in scope and complexity, there is not a clear answer to this question. If we were to assign a t-shirt size to projects, we can give you the following indication:

- Small = 2-3 months
- Medium = 4-6 months
- Large = 6+ months

If you're not sure whether your project is small, medium or large contact our team to discuss it and we'll be able to help you.
