Must-Have Apps for Kids Under 5

Young kids can play and learn on mobile devices

When it comes to screen time, tablets and smartphones have a great advantage over the television; they are interactive. Recent studies have shown that smartphones and tablets can be just as effective as books for children as young as 2 years old, and parents can interact with their kids while they are playing, which has been shown to aid in learning.

The American Academy of Pediatrics has relaxed its guidelines on screen time for kids, allowing for 1 to 2 hours of screen time a day depending on the age of the child.

Now the question becomes which are the best apps for toddlers, pre-K, and kindergarteners. Here's a selection of the best mobile apps for kids who are 5 and under.

Endless Alphabet

Endless Alphabet is among the best apps at reinforcing phonetics and can be used as an excellent teaching tool. The app spreads letters on the screen like a puzzle, and the child puts the puzzle together by moving the letters into place and forming a word. While the letter is being moved, it repeats its phonetic sound, and when it is put in place, the app says both the letter name and the phonetic sound it makes.

One way to use this app is to ask your child to pick out a particular letter. The app can be great for two and three-year-olds to learn their letters and can help kickstart four and five-year-olds into reading.

The Monster at the End of This Book

"The Monster at the End of This Book" was a mainstay of just about every preschooler's book collection in the '70s. Now, the familiar Sesame Street classic has been animated and digitized to bring fun with Grover to smartphones and tablets. Each page contains hands-on activities for your young children. They can tickle Grover by tapping on him on the screen or touch a wall to knock it down. The spoken words appear on the screen to encourage word recognition, and the topic of monsters or anxieties can be addressed with your young ones in a friendly setting.
