Your smartphone is great for a lot of things, but most importantly it can keep a child entertained in a time of need.
Netflix
Having Netflix on your phone or tablet is like carrying around a television in your pocket; you're able to pull up your child's favorite movie or TV show with just a few taps. It's a perfect distraction while waiting for a meal, on a road trip, or waiting in line at the super market.

Toca Hair Salon 2
Giving a random stranger a haircut doesn't sound very appealing in real life, but doing it in a game is tons of fun. Your child can cut, color, shape, regrow, wash, and curl the hair of random subjects -- and laugh the entire time.

Camera

Finally, don't overlook the obvious: The camera on your smartphone can provide hours of entertainment. Teach your kid how to take a photo or video, and then sit back and see what he or she comes up with. The best part: Create a folder on your computer to archive just your kid's photos and videos so you can later look back on them.
