Project summary

An intuitive pay to drive app for commuters in London

Transport for London (TfL) manages all of London’s public transportation. They had an old app that needed to be revamped. The app allows people to pay congestion and ULEZ/LEZ charges.

Thumbmunkeys built a new app for iOS and Android, worked on UI/UX and development, redesigning the app from the user’s perspective.

We also implemented business requirements for the backend. We continue to provide support and maintain the app since launch. The app helps commuters pay charges on the go or in advance using the Auto Pay feature.
