Dec 15 (Reuters) - A group of former Googleemployees are betting they can boost the world's medicalknowledge with a mobile IQ test.

Hi.Q, a free app for the Apple Inc iPhone and iPadlaunching on Monday, includes 10,000 questions across 300topics, such as food allergies, childhood health, and portioncontrol. After taking the test, users are given a breakdown oftheir expertise across certain health areas.

Founder and Chief Executive Officer Munjal Shah, who soldhis prior company Like.com to Google Inc in 2010, saidearly data show a strong correlation between health literacy andobesity. Shah's team is also tracking whether a person's healthknowledge correlates with the rate of hospitalizations.

The Hi.Q team believes that Silicon Valley jumped tooquickly into developing wearable devices to track fitness andwellbeing. A recent study from research firm Endeavour Partnersfound that one-third of people who owned a wearable stoppedusing it after six months.

Shah believes the first step to get more people engaged intheir health on a daily basis should be "quantified knowledge."

"Wearables are ending up in a drawer, I believe that'sbecause most people fundamentally lack the practical knowledgeto stay healthy in the modern world," he added.

The company said 250,000 people have already used the app inits trial phase. According to Shah, 84 percent of those whoopted to take the test were female. The most engaged users aremothers between the ages of 30 and 60.

Shah told Reuters he started kicking around ideas for ahealth startup after some first-hand experience with the currentU.S. health system. After settling on health literacy, herecruited some fellow Google employees to join the team.

The app's founders are primarily drawn from the techsector, rather than the medical field. To ensure accuracy, Shahsaid the questions have been carefully vetted by subject matterexperts, such as a former orthopedic surgeon for the U.S.Olympic team.

The team is more focused on building the product rather thanmaking money in the coming months, said Shah. He stressed thatthe company would not sell data on people's health knowledge tomedical insurance providers.

The Mountain View, California based company has previouslyraised a small and undisclosed seed round of funding fromSilicon Valley venture firms, including Greylock Partners, MenloVentures and Rock Health.
