A growing contingency of health insurance companies are marketing mobile health apps to, ideally at least, better serve their members. But that can be a tough pursuit, opening payers to scrutiny and raising questions about the very experience they're trying to offer.

A review of apps offered by more than a dozen insurers in the iTunes store reveals a wide range of mobile options being offered and a broad array of consumer sentiment about them — from “This is a Rolls Royce” to “This app is prehistoric."

“I think the people who set up the Obamacare website practiced first on this app,” wrote one reviewer of a Blue Cross Blue Shield app with a basic suite of services (a provider directory, claims and benefit viewer and email-a-question service). “With all the money insurance companies make they should be able to make a snappy and user friendly app. There’s really no excuse,” wrote another reviewer of the same product.

From Aetna to UPMC, we look at a baker's dozen of the offerings that payers are bringing to market for their members. View the slideshow to learn more about each.
