Unrack is a mobile platform that allows people to sell or rent out their sports equipment to people in their area. Users can create listings and determine a price for their items while also uploading photos and writing a description. The app then allows others to message and discuss the item and its price before making a final transaction. Unrack helps people save money on sporting equipment and reduces the number of new items that need to be purchased, allowing people with low accessibility to equipment to be more active and reduce the amount of waste produced in the sporting industry.
