Delivery apps were winning the speed war. We rebuilt the app around one tap to checkout — mobile sales doubled.
01
The starting point
Charli Charging helps EV drivers find and pay for charging stations. It gives users a simple, minimalist way to create an account and get charging, with real-time updates on station availability and pricing so drivers know where they can charge and what it will cost before they arrive.
For a driver who needs a charge, every extra step is friction at exactly the wrong moment.

Where the work was actually breaking down?
For a driver who needs a charge, every extra step is friction at exactly the wrong moment. Account creation and login had to be effortless — a driver standing at a station shouldn't be fighting a sign-up flow before they can plug in.
Friction at the worst moment
A driver standing at a station shouldn't be fighting a sign-up flow before they can plug in.
Slow account creation
First-time sign-up needed to be effortless, not a drawn-out setup.
Payment had to disappear
The charging moment itself couldn't involve navigating a checkout.
End-to-end delay
The job was to remove that delay end to end, from first-time sign-up to payment at the charger.

What Singular built
We integrated authentication providers so drivers could sign up and log in fast, without a drawn-out account setup.
Fast authentication — Third-party authentication providers integrated for quick sign-up and login.
NFC at the charger — Quick identification and payment at the station — tap to charge, rather than navigate a checkout.
We treated the visible interface, the operating workflow, and the underlying data model as one system — coherent for users and practical for the team maintaining it.
A streamlined charging process for drivers, from first sign-up to tapping to charge.
