I'm the Director of Online Marketing for KingFit Preventive Health & Wellness and I would be remiss if I didn't at least drop a line in on this thread.

We're currently developing a mobile app + clinician dashboard combo working towards a preventive health solution. Our main focus is diabetes right now but cardiovascular disease, prediabetes, and type 2 diabetes are all in our sights here early on.

Many of the apps functions revolve around simple dietary and exercise solutions to combat these illnesses. We also plan on using IBM's Watson to improve suggestions for the patient and the doctor.

We're still early, but check us out at https://kingfit.org
