State Farm's mobile website was ranked best in its class, and USAA came in first for best mobile application in a study of mobile technology used by auto insurance companies. Key Lime Interactive, a customer experience research company in Doral, Fla., conducted the study.
The company rated the technology for customers' ability to submit bill payments, view policy details, enter accident information and get auto insurance quotes without revealing sensitive personal information.
Six other auto insurance companies were included in the study besides State Farm and USAA -- GEICO, Progressive, Nationwide, Travelers, Allstate and Liberty Mutual.
State Farm said it will continue to improve its mobile technology.
"We're always listening to customer feedback and are evaluating new technology that will make it even easier to use," Patty Gaumond, State Farm's vice president of enterprise Internet solutions, said in a press release.
Meanwhile, USAA, which serves people in the military and their families, reported that member use of its mobile tools grew by 127 percent last year over 2010.
"Nearly half of all USAA members own a smartphone and by the very nature of their military jobs and mobile lifestyles, they need tools that allow them to help manage their finances from anywhere," Todd Walthall, senior vice president of channel management at USAA, said in a press release. "From paying bills or reporting an insurance claim, to shopping for a car or even a house, USAA apps are becoming a convenient destination for our members."
