Smartphone use in the United States is growing rapidly and focuses mainly on sedentary activities, such as texting, gaming, and web browsing. Therefore, it is important that educators teach students the positive health-enhancing possibilities of smartphones. Apps exist for monitoring food consumption, planning meals, calculating BMI, and recording and analyzing videos. There are also apps that teach yoga, dance, and tennis; measure heart rate; and track step counts. Teachers may incorporate the use of smartphones by introducing such apps in class and allowing students to use them to track their progress, share results, plan projects, search databases, motivate improvement, form collaborations, and submit homework.
