Great animated graphics and some authentic voice overs make this one of the best toddler apps on the market!" ~Static451 "I am enjoying it big time. My son even enjoys it he's only 15 months can sign bath and eat. He tries to do finish but he can't get his hand right, but he loves sitting there pressing it to watch the signs." ~T.L. "The layout of your app is amazing to say the least and my one year old who already knows some signs was so into the babies signing instead of the adult that we see in most videos and other apps." ~Victoria "My granddaughter is 6-months and when she sees my phone she reaches for it and pushes the buttons to see the babies...she loves to look at them" ~Olivia "Winner! I love this APP ! I looked for a long time before stumbling across this one, it is by far the BEST. I used to work in pediatrics & did a lot of co-treats with speech therapists & learned a lot from them. As they say, "If you don't use it, you lose it" , that happened to me. I especially love the feature of being able to watch the sign ! I highly recommend this for ANY parent/caregiver! Thank you for this incredible app!!" ~Discojd "Love this app My whole family has learned so much from this app. I have 3 kids 8,7 & 3 years old and they are all learning with this. I have told other parents about it too!" ~Mommy Renee "Awesome My baby loves this app. She has learned to communicate her needs quickly & loves to watch the babies." ~mamacita3 "Love it checked different apps and this one is the best!
