No Microphone

I have been using this app for years. Recently transferred to an iPhone, and my world has turned upside down with this app. I can no longer use the microphone on the keyboard to dictate the message that I need to send. I am hard of hearing and hard of vision so I depend on the microphone to be there. It was only recently that they took this feature away. I tried to contact the developer, and it just circles me back to their support page. I am in the process of finding a different relay app that can cater to my needs.

Buggy, fix please?

Hi debris, this app is really buggy, can you please fix? It doesn't cooperate well with system accessibility settings, which means that those of us with multiple sensory issues have to struggle. Scrolling is buggy -- incoming text bounces below the bottom of the window. Incoming call window doesn't expand with larger font sizes, which makes incoming calls difficult /impossible to answer. But even if I do manage to hit the right, tiny button, incoming calls don't always answer, anyway. And your system often cuts me off, I'm assuming because I have a slow, rural internet connection. Which means us rural customers need more support, not less. Also, if you could make the browser and app options and interfaces more similar, that would be helpful, especially for those of us with vision difficulties. Thank you for checking into these issues.

Buggy; needs sound support.

This is still buggy. When I tried to answer a call from a potential employer, I was unable to type anything and had to end the call.

I wish we could have sound alerts. I recently contacted Support and inquired about sound alerts. The Support person said that this app is geared towards deaf people and it doesn’t need sound alerts. That’s patently false. This service is also geared towards mute people; it says so right in the description and on the Web site. I often miss important phone calls because I don’t hear the phone. Deafness is not binary; it is a range. I would appreciate sound support so I can be alerted to incoming calls. I may have to find another provider if this need is not met.
