First there were online medical sites. Now health apps are exploding. But which ones can you trust and how can you use them responsibly?

Dr. Wendy Sue Swanson, pediatrician with the Everett Clinic and known online as Seattle Mama Doc, shares some much needed guidance.

Dr. Swanson says health apps have taken do-it-yourself to a whole new level, for better for for worse. She gives a thumbs up to those that help track diet and exercise.

However, when it comes to dianosis, watch out. A study in JAMAfound that three popular apps claiming to detect melanoma missed the cancer on average 30 percent of the time. Dr. Swanson says, at best, apps and online resources are only helpful tools, not replacements for your doctor.

The FDA currently does not have jurisdiction over smartphone apps; however, the FTC was able to shut down two apps that claimed to treat acne with a blue light.
