Not a great app for sign language....
If you want to learn the alphabet, places and family members in sign language then it is a good app, but if u want to learn colors, time, money, emotions and other words in sign language you have to pay. The people who made it are just trying to get more money from you. I would suggest a different app if you want to learn sign language because there is probably another app that doesnt make you pay to learn lots more words than this app.
