With over 17,000 health and medical apps available in iTunes, and with an average price at around $2.00, iTunes ?Health? and ?Medical? categories are two of the fastest growing sectors of app development. There are health games that offer, for example, quizzes to assess calorie content of various foods. There are GPS apps, order tracking apps, weight management apps, pedometers, diabetes regulating apps, and calorie counting apps, just to name a few. These apps might be associated with push notifications that offer users reminders to take meds or other health interactions.
