Tred mobile app for tracking carbon footprint

Project summary

Enabling effortless carbon footprint tracking

Tred is an environment-focused startup. They offer a green debit card that plants trees as users spend and allows them to track their carbon footprint through open banking. They were looking to develop a native iOS app with the .NET Core framework.

We came up with new designs and look and feel with an optimised UX. The app enables carbon footprint tracking for users by tracking and categorising transactions.

Users get eco-tips, insights and articles to reduce their carbon footprint. They can also offset their carbon footprint by choosing from a range of verified offset plans.
