Best Toddler Apps

What are some apps for your phone/tablet that your toddler loves? Preferably something without ads and that is free. lol

DH has 'words with cats' on his phone for Heathen. It helps her learn to spell/read.
But then, she's almost 4, so I don't know how well that work for Bug

Elmo Calls. Best app EVER. I think it costs 99 cents or something though.

We have My Baby Fireworks, where she touches these shapes on the screen and makes them blow up into pretty fireworks. It's her fav.

Toddler Lock. It's free and it locks the phone so that she can press any button or anywhere on the phone and nothing happens until you click out of it by clicking each corner clockwise. It basically just makes music and when she presses it different shapes and sounds come up, or she can draw with her finger like on paint! My daughter loves it- she's almost 16 months!

My daughter LOVES "Smart Toddler School Pro++" app! As my official 2 1/2 year old product tester, she can attest that she loves her "Smart Toddler School Pro++" app, referring to the alphabets, numbers, Colors, Shapes and Counting. I spent many years as an elementary school teacher convincing parents and students that sitting on the couch watching TV was not the ideal way to spend the afternoon. The app, in a very animated fashion, teaches to learn the alphabets, colors, shapes and numbers. Why is it a Smarty Product of The Week? Let's just say that my munchkin is running around telling me every alphabet, number, shape and color she can find in the house. "What color is it?"! Can't argue with that!

"I can't tell you how much my son loves "Smart Toddler School Pro++" app. After a week, he knows every word, and walks around all day singing ‘Red... Apple... Red... Apple.... Red, Red, Red.' etc. Thanks for being so creative. He's really learning his shapes. He loves to tell me how many points a shape has. He will say ‘Please give me that pillow...the rectangle one with four points?' Also, the tracing letter, alphabets with graphic sound scheme is fantastic.
