A Fitbit can monitor a number of significant aspects of your health and fitness. It can function as a pedometer and measure your steps while keeping track of the distance you have traveled and the number of calories you have burned. This is useful information indeed, and can be used to determine whether or not you will do additional exercise. But, and possibly more important, it monitors sleep. It can record how many times you awaken during the night, and the quality of your sleep. Sleep apnea is serious, and one can be alerted to have testing performed if snoring is excessive. But, if a person lives alone there might be no one to hear that snoring. This device might be the only way a person would know that testing for sleep apnea is needed.
Some units function as a watch, provide heart rate continuously, elevation climbed, and even can become a GPS system. The higher priced units have more features.
