E-Commerce Mobile Application

Gem is a user-friendly mobile application that is available both in iOS and Android. Gem allows users to explore new items that are being sold near them while giving the option to post their own used items to be explored and found by our community. Gem is the better version of Cregslist. Once a user finds an item they like they can contact the seller and discuss pricing and purchase details. Users can also search for items by their name and category.
