Gixen eBay Auction Sniper is a free iPhone app developed by Mario Vodopivec. Designed for eBay users, this app allows you to automatically place bids on auctions at the last moment. With Gixen, you don't have to worry about manually monitoring auctions or staying online until the auction ends.

One of the standout features of Gixen is its automatic bidding capability. Once you set up your bid, Gixen will place it for you within the final moments of the auction, increasing your chances of winning. The app also offers group bidding, where the first successful snipe cancels all the other bids in the group.

Gixen eBay Auction Sniper is currently available for free, although pricing may change in the future. If you're an eBay enthusiast looking for a convenient way to bid on auctions without having to be online, Gixen is definitely worth a try.
