The Quantified Self website provides a current list of many of the self-tracking tools out there.

From the Smart Patient website: Smart Patients is an online community for motivated patients and their families and friends. Here you can learn at your own level about scientific developments related to your disease, share your questions and concerns with other members, and use what you learn in the context of your own life.

We believe patients are the most underutilized resource in healthcare. We've watched patients become experts in their diseases — and we see that their knowledge improves the care they receive. With the right tools, you and other patients can do the same.

From the ACOR website: "ACOR online communities are for parents, caregivers, family members, and friends to discuss clinical and nonclinical issues and advances pertaining to all forms of a specific disease. This includes patient and caregiver experiences, psychosocial issues, new research, clinical trials, long-term side effects and discussions of current treatment practices."

From the Ringadoc website: Ringadoc gives you direct access to doctors. We cut away all the barriers between you and the care you need, bringing immediate care straight to your nearest phone. During your call, the doctor you speak with will be able to provide medical advice, diagnose an illness, advise you on treatment, and when necessary, prescribe medication.*
Our service is now available with complete video conferencing for smartphones and tablets.

From the Prevent Cancer Foundation website: As more is known about primary prevention and lifestyle changes that can reduce your risk for cancer, most research indicates that starting at a young age is an important factor in adopting lifetime habits. Unprotected exposure to the sun, tobacco use, and childhood obesity are all factors that lead to an increased risk of cancers in adults. You may be at greater risk for some cancers if you have a personal or family history of cancer or certain diseases. To help determine your risk, complete this family medical history chart and share it with your health care professional and other family members.
