Why I Love Tonic: Ronald Simons, Weehawken, New Jersey

"I use Tonic to help track a variety of supplements and medications. This is especially useful for me as I am an entrepreneur and operate in a climate of constant scheduling changes for meetings, conference calls and production location visits. I look forward to using Tonic to help keep me on schedule for my weight training and cardio workouts." -- Ronald Simons, Weehawken, New Jersey

Why I Love Tonic: Julie Desch, Palo Alto, California

I'm 50 years old with cystic fibrosis (CF). A lot has been discovered lately to help people with CF, and I benefit from much of it. The problem is that it seems the more that is discovered, the more there is to remember to do. New medications, new types of treatments, more emphasis on exercise, more aggressive treatment of lung infections with IV antibiotics...it all takes time! Add normal activities of life to this, and chaos easily ensues. Serious organization is required, and Tonic fits the bill. Cystic fibrosis is not an easy illness to live with, but Tonic makes it more manageable. -- Julie Desch, Palo Alto, California

Rajiv Mehta, creator of Tonic, in today's New York Times

If you caught the article, "A Dashboard for Your Body," in the August 4 edition of the New York Times, you saw writer Farhad Majoo's profile of five mobile health apps that track a variety of health-related metrics, including calorie burn, weight, body fat, body temperature, blood pressure, and more.

Rajiv Mehta, creator of the Tonic Self-Care App, wrote in response to the NYT article, noting that many of the tools profiled in the piece focused on long-term tracking of health, while millions of Americans -- especially those with chronic diseases like diabetes, high cholesterol, and arthritis -- also need help tracking day-to-day health, symptoms, and staying on top of tasks like adhering to a medication regimen.
