US-based mobile shopping assistant ShopSavvy has released its latest version, ShopSavvy 5, in Apple's App Store and the Android Market. ShopSavvy 5 offers enhanced features including one-tap purchasing for shoppers who want to buy products online from Walmart, Target, Best Buy and other major US retailers.

ShopSavvy has expanded its recently introduced one-tap shopping feature to enable in-app purchasing from a range of retailer websites, including Walmart.com, Target.com, BestBuy.com and BN.com. With one-tap shopping, ShopSavvy users who scan an item in a store and see a better deal online can purchase it immediately without leaving ShopSavvy. All it takes is the one-time entry of payment information in ShopSavvy's mobile wallet.

With the ShopSavvy 5 release, ShopSavvy has also enhanced its keyword search functionality to enable scrolling through relevant results for items on consumers’ shopping list.

ShopSavvy 5 also extends ShopSavvy's mobile comparison shopping capabilities with more data from the company's more than 40,000 retail partners. This includes expanded price-matching data, so shoppers can determine whether a local retailer is willing to match the prices displayed in ShopSavvy results.

ShopSavvy announced earlier this month that it has secured USD 7 million in Series A funding in a round led by Eduardo Saverin, Facebook co-founder and private investor, who has joined the company's board of directors.

Since launching in 2008, ShopSavvy has had more than 20 million downloads and has over 10 million current unique users. With investors including Facebook co-founder Eduardo Saverin, ShopSavvy brings real-time pricing and product information directly into a consumer's hands.
