Almost impossible to download

Tried a number of times to download and install the app it failed each time finally gave up on it. If it doesn’t work any better than it installs it’s not worth having

Not tty

They implied that this is the way to assess the tty operator without any need to buy and hook up a portable tty machine to the cellphone. It only works from cellphone to cellphone users who have real time text on the cellphones. I can already text friends. I need portable easy TTY with a real operator taking the phone calls.
