"Terapeak Marketplace Research, an eBay Certified Provider, announced the launch of an iPhone application that allows users to conduct eBay market research on the go. The service is available to all North American subscribers of Terapeak's web service at no extra charge. The application allows users to enter their search term and, with one click, access item-specific data based on 45 days of closed eBay listings.

The Terapeak iPhone app allows users to see average prices, listing totals and sell-through rates for each search. Results are viewable and sortable by end price, start price and number of bids, and can be filtered by category, minimum end price and maximum end price. The application is the first and only eBay market research tool available to iPhone users, according to the company.
