Compared to the other app, Baby Sign, this app is a tad more helpful...for adults. It includes explanations but it could seem long winded since most people probably only need to "see" the sign. Hence, kids probably will get bored easily. My 1.5-y/o can watch the other app one sign after another, but this app, he just wants to exit out of it. This free version includes more words/signs than the other free version.
