"Working with Matt and the team at Growth For Purpose has been a game changer. Their strategic thinking, attention to detail, and deep understanding of the psychology behind product design helped us bring clarity and structure to a complex project.

They didn’t just deliver beautiful, thoughtful UX — they brought insight, energy, and a clear path to growth. Matt’s depth of knowledge and the team’s collaborative style made the whole process feel seamless.

Highly recommend for any product team serious about impact."

Background

VoltaRocks is a free app designed to help Aussie households take control of their energy. It shows where you're using power, helps you switch to better energy plans, unlocks rebates, and gives smart tips for going electric.

Key Goals

• Lower cognitive load and improve user engagement throughout the app
• Deliver generous value through quick-win responses in the onboarding process

Our Role

We apply habit-changing psychology to drive and boost performance across key metrics from acquisition to retention, while strengthening VoltaRocks’ ability to help Australians take control of their energy.

Note: Designs are published with the client's permission

VoltaRocks caters to a diverse user base, from those keen on saving money to eco-conscious individuals aiming to reduce their carbon footprint. By understanding and mapping these varied motivations, we've crafted an experience that resonates with all users, guiding them toward meaningful energy-saving actions.

Goal: To deliver an engaging and value-adding initial experience for all types of users

We designed and developed a quiz-based onboarding journey that encourages users to invest their time and attention through interactive questions and value-driven responses that demonstrate how Volta can help. As users progress, they receive personalised tips and insights based on their answers—sparking curiosity, building anticipation, and keeping them motivated to complete the experience.

Keeping Users Engaged Every Step of the Way

As users progress through the journey, the progress bar at the top of the screen reinforces their investment of time, making them less likely to abandon the experience. Engaging copy that uses conversational language—combined with a compliment, a quick tip, and a clear highlight of how Volta adds value—helps boost both acquisition and retention of new users.

Final Steps

As users near the end of the onboarding journey, they’re prompted to select a personal goal (tapping into intrinsic motivation), secure their account, and choose their preferred onboarding experience. If their energy provider appears in the dropdown list, they’re seamlessly directed to the final screen shown here.

Building Trust


VoltaRocks builds user trust by clearly communicating what data will be collected—accessible via an information icon—and by transparently highlighting the benefits of connecting their CDR. Importantly, users are given the option to connect their data later, which increases trust by offering flexibility and control.

DASHBOARD

Building Energy Habits with The New Home Base

Goal: To lower cognitive load and friction for all users providing an intuitive in-app experience without the learning curve

Users are subject to a value-adding experience from the start with their energy usage all the way down to displaying their plan details and a flashcards module. Through visual hierarchy, the most important information is displayed at the top where users can easily understand and track their process and energy usage. 

Micro-Rewards
Placing the upcoming bill at the top—and highlighting the 2% drop—shows users they've successfully reduced their energy use. This positive reinforcement motivates them to keep checking the app, creating a habit loop that builds long-term engagement.

Social Comparison
Users are able to compare their energy usage against other households in their area with similar backgrounds e.g. 2 people, living in an apartment. This creates friendly competition and motivation as to decrease their energy usage.

Micro-Learning
Through the use of flashcards, users are able to interact and receive tips, facts and actionable steps in reducing their energy usage and this lowering their bill. This also allows Volta to further personalise the user’s experience and keeping them engaged with the app.

Not every user can connect their data right away - when a user’s provider isn’t supported by CDR or they chose to skip if their provider is supported, their journey may feel disrupted. To combat this, we designed a new dashboard state (without CDR connected) to turn this moment into a clear, low-friction step - prompting users to upload their latest energy bill so they can continue their energy journey without disruption.

Designing for Every State

The VoltaRocks dashboard was built to support users at every stage of their energy journey—even when data is missing, delayed, or in transit. We designed distinct states to keep the experience transparent, consistent, and motivating.

PLAN HUSTLER

Helping Users Hustle for a Better Energy Plan

Goal: To remove friction, build trust, and empower users to take control of their energy costs in just a few taps. 

Finding the right energy plan is often confusing and time-consuming. With Volta’s Plan Hustler feature, we set out to simplify that process—helping users compare plans quickly, understand their savings, and switch with confidence. 

Making the Switch Seamless

Once users find a better plan, the experience doesn't stop there. We designed switching journey to feel simple, supportive, and stress-free  -eliminating common barriers like confusing jargon, unclear steps, and long wait times.

From start to finish, users are guided through exactly what to expect. Clear next steps, timely reminders, and upfront transparency make the process easy to follow and instill confidence at every stage.

Each touchpoint is thoughtfully designed to build trust and maintain momentum. With proactive nudges, instant access to key plan details, and real-time dashboard updates, users stay informed, empowered, and fully in control from switch to success.

Driving Growth Through Shareable Moments

SOCIAL SHARING

Goal: To drive user acquisition and growth through social sharing strategies

We applied three immediate quick win strategies to key screens during this first phase. This includes IAM (In-App Messages) share prompts, sharing content and inviting friends via a prominent CTA button.

GLOBAL STATES

Designing for Every Scenario

Like every digital experience, you never know what will happen from offline and loading errors to server and maintenance updates. This is why we’ve designed for three different global states: Offline, Plan Hustler is Down, Error. Each with their own different variants.

Mapping Out the Whole Journey

USER JOURNEY MAP

To wrap up the end of the phase, we mapped out a whole user journey from onboarding, switching plans to potential error states. By zooming out and considering all the possible flows that a user may take, we designed not just the screens but meaningful and seamless app experience.
