Cellphone usage has grown in the past 20 years. At least 94% of Americans have one. We use our cellphones roughly 16 hours a day, and we check them at least 150 times per day! Today’s “smart” cellphones and other devices can host a variety of mobile applications. These “mobile apps” are internet applications that are designed to work on smartphones. App usage has grown so much because apps work faster than websites, a well-designed app can perform functions more quickly, and apps usually store the data locally on the mobile device. There are currently over 3 million apps available for use. You can use apps for buying meals, tracking your daily exercise routine, and even maintaining your personal finances.
