I love this app and my 2 year old has learned numbers and music instruments.
He loves dragging the instruments to the stage. Highly Recommended!!

Excellent app for kids

Another great product from The Melody Book! This is the perfect app if you want your children to learn to count and be expose to new language. My nephew enjoyed it and even I like it because it comes with different languages and it's very interesting to learn to count in other languages. The price is reasonable and the graphic stupendous!

Jazzy numbers? Oh, yeah!

After enjoying the Jazzy ABC app do much - I was excited to hear about the Jazzy 123. At first I was wondering - what's it all about? And then I realized - it's about counting instruments and by that learning their names and the sound they make! Such a great comprehensive way to learn! And of course the kids are loving it! Looking forward to hear about the next app on the Jazzy series!
