HeatSignal.app

HeatSignal helps sneaker collectors hunt grails across the entire resale market without opening multiple apps. The feed aggregates publicly listed inventory from major resale sites, boutiques, and collector channels into a single timeline you can filter by silhouette, brand, size, and price. You follow specific pairs to get push or email alerts the moment something matches your criteria, including price drops on listings you’ve already seen. Upload your sneaker collection to get an instant collection value. Post sneakers for sale on the HeatSignal Marketplace and have items authenticated through our sneaker authentication partner LegitApp.
