Total JUNK

This app has always been unreliable for incoming calls on my Samsung cell phone, so people just stop calling. I have followed their app support directions to the "T". The Hamilton app simply fails to work as they claim, and I don't expect it will be any more useful on the new iPhone that I will be buying this year. I have given them the benefit of time (2 +/- years) to make this a viable app for the deaf and hearing impaired community, but Hamilton Support has been unable to fix things - I have tried everything that they have suggested - to the point of utter exasperation. Needless to say,I have had it with Hamilton. IMHO, this App is a fraud and an insult to the hearing impaired community... not worth your time.

I got this app so my 7 year old son can talk on the phone. He has 2 types of hearing loss, each ear is different. One ear is moderate and the other ear is severe. I used it for the first time today on iPhone 6 Plus. No issues with logging in as previous reviews mentioned. The only issue was with the CapTel person either lagging about 10-20 words or the app causing additional lag time. I suspect it's the app as suddenly the words would be all there. I live in the same town as the Relay provider Hamilton.

Works WELL on iPhone - UPDATE IT

Prior to iOS 11, I used this app all the time for making outbound calls. It was relatively flawless in that aspect. I have never used it for inbound calls as I simply have people leave a message and either email/text when I need to.

PLEASE update this to work on iOS 11 as it is cumbersome and far glitchier (if that is a word) using the web based CapTel on a phone than the app.
