Top health applications on Android

In most developing countries, mobile health (m-health) applications are being developed to target rural mobile phone users who do not have access to medical services.
In developed countries, however, people use mobile health applications for much more than just medical treatment. They use apps when they're expecting a baby, or to keep track of appointments with the doctor, and to maintain medical records or count the calories they're consuming.
Android, one of the most popular mobile operating systems, also offers an array of m-health applications that it regularly updates.
