So I had high hopes for this app,
lets start with the good: the letters seem correct, I love the animations, there are also numbers and simple signs you can make, multiple colors, and easy to install.
Now the bad: the color defaults each time you switch to the keyboard and it defaults to pink hands, to make a simple sign such as more you have to switch from left to right handed screen to get both sides, you must copy and paste the text to your message to send it, the hands are larger than emoji, it also send the message as a picture therefor you must click on it to see the entire text and it may use data to send like an image would.
Overall: I dont like it. I just wanted to send ASL to some friends like an emoji but it is a pain to copy paste and then it still sends as an image not as emojis. I would not recommend spending money on it
