Whether it's recognizing letters or a friend's feelings, these choices help little ones learn in a fun way. Many grow with your child's abilities. Plus, they all have solid parental controls and are free of in-app purchases (so your 2-year-old can't drain your iTunes card).
Sago Mini Friends
Toddlers choose one of five adorable animal characters to take on a walk down the block, visiting neighbors. Each house offers different experiences that teach cause and effect, like watering a plant to see it grow or pressing on balloons to watch them inflate and fly away. "My 2-year-old son liked ringing the doorbells because every so often, one honks," says a mom tester. 2+, $3, Apple only
Dr. Panda & Toto's Treehouse
Within the four rooms of the treehouse, kids help the baby turtle find what he needs. "I loved hearing my preschooler laughing as he gave the turtle a sudsy bath and a healthy veggie sandwich," says one mom tester. 3+, $3, Apple and Android
Potty Time With Elmo
Through songs, books, puzzles, and a reward chart, much-beloved Elmo encourages kids to use the potty. "My daughter wanted to sit on the toilet the first time we used the app," says a mom of a 24-month-old. 2+, $3, Apple and Android
Kids select a word from a giant monster's mouth, see and hear it, sound it out, and watch an animation that demonstrates its meaning. New words are added regularly, and there's no "C is for cat" here; C is for cooperate. Says a mom tester: "My 3-year-old loves when the monsters run over the letters in a word and she has to put them back where they belong." 3+, $7, Apple and Android
Toddlers begin by sliding a circle into an obvious hole. But this app, based on Jean Piaget's theory of cognitive development -- that the youngest children learn about their world by exploring and manipulating it -- quickly ramps up by blocking paths and hiding objects. "My son was able to navigate some of the tougher levels once I guided him a bit," says a mom of a 2-year-old. "I find myself playing this when I'm waiting to pick him up at gym class." 2+, $2, Apple only
In this virtual dollhouse, kids can pick characters of different races to make a pretend family that goes about household activities, like cooking eggs and running water for a bath. "There's a lot to do, so set a time limit up front since the app doesn't have a natural ending point," suggests one dad tester. 3+, $4, Apple and Android
The eight games in this sweet sea-themed app focus on numbers, letters, shapes, and colors. "It was intuitive for my 3-year-old to use," says one mom tester. "For instance, when he swipes the alphabet from right to left, the letters go backwards." 3+, $2, Apple only
It taps early math skills by taking advantage of a natural childhood inclination -- counting on fingers. When kids press the screen, they see a numbered character appear that fingers they're using. Then they hear the number aloud -- you can even record your voice saying the numbers. "After a few minutes, my preschooler did simple addition for the first time," says one tester. "When the problem was '3+1=', he would put three fingers from one hand and one finger from the other hand to make 4 on the screen." 3+, $2, Apple only
Daniel Tiger's Grr-ific Feelings
Games, a photo booth, songs, and art in this app help kids identify their emotions -- whether it's frustration or happiness, love or jealousy -- so they can better express what they're feeling inside. 3+, $3, tablet only
