HealthVault is an online service from Microsoft to track, record and store health/medical related information. The Windows Phone app, HealthVault, is a mobile client for this service to let you have access to all your health and fitness information while on the go.
The HealthVault service lets you document your medical information, list emergency contacts, track chronic conditions, and upload medical documents (via the online portal). Online access will also recommend health and fitness apps for your Windows Phone.
HealthVault, the Windows Phone app, lets you access all your HealthVault information as well as add information or edit existing data. The main pages of HealthVault will display your information with access to your health information, measurements, and profile. There is also a Family Page that will display your family members accounts.
The health information link will take you to a listing where you can view, edit or add information on allergies, medical conditions, contacts, family history, immunizations, insurance, medications, and medical procedures. From the measurements link you can track your weight, height, blood glucose, and blood pressure.
HealthVault is a handy application to keep your medical and health information handy. For example if you've had adverse reactions to a certain medication, you can document things on HealthVault and when your at the Pharmacist that information is at your finger tips. Or, if you can't remember you child's medication allergies, HealthVault can help you there as well.
