A growing number of gadgets promote greater physical activity, better sleep, reduced stress and nutritious eating, all in the name of living a healthy lifestyle. Many gadgets have spurred the self-monitoring movement that some have described as the Quantified Self (QS).

Whether you're a QS fanatic or a casual user, you'll see that these digital tools can motivate you to improve your health.
