The app's main features include the ability to view specifications of a large collection of modern PC components, compare prices between Amazon, Walmart, Best Buy, Newegg, Adorama, and more, and add PC parts to an unlimited amount of custom builds, which are stored locally and available offline. With BuildCores, users can also see what parts are compatible with their PC build, catch the best deals on the latest and greatest PC hardware and accessories with the BuildCores Sales Feed, and enable notifications to snag the latest deals.
