The mobile health market is growing like a weed these days. According to mHealthWatch and eHealth Initiative, there are 31,000 health and medical-related apps on the market today. In fact, over the last year, the number of health apps jumped 120 percent, and hundreds of apps now hit stores every month. Yet, in spite of this exponential growth, the mobile health space is still in its "Wild West" phase. In other words, it's a work in progress.
