Whoop you're right forgot about that....and I agree. I don't have any apps related to VRS and IP/text relays on my phone. I have VRS on iPad but never used- likely can't now anyway- outdated. I use PC or the Z70.You are correct however I use the computer version as I cannot see on the small screens since I am deaf/blind. So I glad they offer that as an option too.
FYI - Apple just released the latest IOS & MacOS version with one of few new features to use as "TTY".Can I use it on IMac? Just wondering.
