A survey in the US has found perhaps unsurprisingly that weight loss and exercise apps are more heavily downloaded by far than any other type of health or wellness app.

In addition, the survey by AhHa! Insights found that iPhone users are seven times more likely to pay for a mobile health app than their Android counterparts. But medical reference apps were downloaded ten times more by the Android users.

The survey by AhHa! Insights says weight loss and exercise made up 60 percent of total downloads of health apps for iPhone and Android handsets, followed by women’s health, sleep and meditation, pregnancy, tools and instruments, reference and emergency.

Finally the research firm says nowhere in the top 150 apps for iPhone and Android did it find significant downloads of connected medical and health apps such as blood pressure monitoring so that mhealth’s potential in terms of monitoring, diagnosing and providing real-time results “falls short here”, according to Abe Kasbo, CEO of Verasoni Worldwide, the parent company of AhHa! Insights.
