Doesn't really work – ASL SwipeKeys Review

I have a iPhone I sent a message to my friend who has an android he's then only person I sign with and in my messages I saw the asl letters but he got strange little boxes. I tried w another friend who has an iPhone and the same thing. So I'm assuming the other person needs to have the app installed too only issue is it doesn't seem to be available on android store. Also I agree with everyone the font needs to be bigger it's really hard to read and yes maybe changing the colour would help too
