Almost good
The app is great. I use it to look up certain words but I make sure I practice the grammar. This is not an app to learn from but more to look up a few words. You need to know the ASL grammar in order to sign more than two words. The video play button covers the signs and I don’t know which sources are right but I’ve heard smart sign is not reliable but I don’t know how to tell if I’m learning a right sign. Other than that it is a great app to learn some words from. If you really want to go in-depth and pay look at @itsada_c on Instagram for recommendations on where to learn.
