Mpire has launched a mobile version of its research tool for eBay buyers and sellers. Mpire launched Researcher for the desktop in January, and now users can now access data about items that have sold on eBay through their cell phones using Mpire Researcher Mobile.

Mpire Researcher gives eBay sellers information to help them make profitable listing decisions, and buyers can use it to help them spot bargains. Users type in the item they wish to sell or buy, and Researcher shows data such as starting price, average selling price. It also makes listing recommendations useful to sellers, such as best listing length and keywords. The data is based on eBay closed listings from the past 30 days.

Mpire Researcher Mobile is free through the initial launch period and then will cost $4.99 a month for unlimited searches.
