A native iOS and Android app designed to make EV charging feel simple, transparent and trustworthy — from charger discovery through to digital receipt.
Session flow and live charging screen — two of the three core journeys delivered at launch.
The end-to-end app — Find, Charge, Pay.
GRIDSERVE was growing rapidly — adding charging sites, customers and infrastructure — but drivers had no reliable way to navigate the network or trust that sessions would work. I led the end-to-end design of the native app as the sole designer, from brief to launch and beyond.
EV charging is a trust problem. Drivers — especially those new to electric vehicles — approach each session with low confidence. They're unsure whether the charger will work, what they'll pay, and what to do if something goes wrong. The real design problem wasn't the feature list. It was the anxiety.
Requirements workshop with the GRIDSERVE product team.
Charging confidence
Drivers could find a charger, start a session and pay without friction or uncertainty.
App adoption
50,000+ downloads and a 4.8★ App Store rating within the first year of launch.
Speed to market
Designed and shipped in under six months from brief to App Store.
Scalable foundation
Design patterns that supported the team's ongoing development long after launch.
Customers don't need more charging information. They need confidence that everything is working.
Early journey mapping used to define the core charging experience before expanding the wider product.
The physical charger provided only basic session feedback. The app extended that experience, giving drivers a clearer view of charging status wherever they were.
Field research at a live GRIDSERVE site — understanding what drivers actually needed from the physical charging experience.
This was the point where I realised customers weren't asking for more charging data. They were asking for reassurance. That insight has shaped how I approach complex products ever since.
Early concepts showing how the app could evolve beyond charging into a broader ownership experience.
The end-to-end charging journey, from charger discovery to digital receipt.
Drivers gained a clear way to charge, pay and monitor sessions from a single app. Early reviews consistently cited confidence and clarity as the reason they kept using it.
50,000+ downloads and a 4.8-star rating, delivered in under six months. The app created GRIDSERVE's first direct digital relationship with its customers.
The Figma conventions and design patterns I put in place gave the team a shared foundation that supported delivery long after the initial contract ended.
This project shaped how I think about trust as a design outcome. Trust isn't a feature — it's the cumulative result of every interaction telling a customer: this is working, you are in control.
The decision I'm proudest of wasn't a screen. It was insisting on field research before we designed anything. Seeing real customers — anxious, time-pressured, unsure — gave the team a shared picture of what we were actually building for. Every decision after that was more deliberate because of it.
Trust is designed long before something goes wrong.
