FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. IP Captioned Telephone Service may use a live operator. The operator generates captions of what the other party to the call says. These captions are then sent to your phone. There is a cost for each minute of captions generated, paid from a federally administered fund. To learn more, visit fcc.gov. Voice and data plans may be required when using Hamilton CapTel on a smartphone or tablet. Hamilton CapTel may be used to make 911 calls but may not function the same as traditional 911 services.

Works but…!!

I have two huge main issues. One, if I put it on speaker it keeps switching back to phone and there are times I don’t even know it happens cause there is a pause in the conversation. Two, it does not work with connection to Bluetooth in my car speakers. It will work for maybe 2 mins and then it will just freeze. I can’t hear them and they can’t hear me. So I have to force close it and start over and turn off the Bluetooth.

Hey RickyD23, thanks for posting these concerns. Regarding the audio switching between speaker back to phone - we've had that same experience using the iPhone, itself, not with the app. And it appears others have as well, when searching this issue on the internet. Given this, it seems this happens occasionally and may not be specifically related to the app.

Regarding the Bluetooth issue, one of our developers tried to replicate this problem and was unsuccessful in having the same experience you had. A couple things we're thinking…some Bluetooth connections/signals are stronger than others (depending on the age of the technology in the car) and/or it's possible for conflict to arise when another Bluetooth device is in close proximity.

And about taking captioned calls in a car…we sure hope you're the passenger when using the app in the car! :)

Audio Issues During Calls

I really enjoyed this app until recently, it gave me the ability to see a transcript of the conversations as it is being spoken. I discovered this app a year ago and decided to try it out. I used this app daily and it worked fine and the captions were fairly accurate.

I have two main issues with the app. First off is with the dial pad. Wen I want to enter a number, the keypad is not fully visible with Voiceover (screen reader software). So, have to turn it off in order to make it wirk, which is frustrating and is still happening. Finally, when making and receive call, the audio sounds very choppy and is cutting out no matter if I’m using speakerphone or a headset.

After noticing the issue, I contacted customer service via email to resolve the situation. It has been two weeks now and I have not receibed a response or a resolution to the problem. Therefore, I have to use a different captioning app.

I love this app so much! The captions r 99.9% accurate! There’s one feature that I would like added, if this app can work offline.

Hi! The app will work either on WiFi or a cellular data connection through your wireless carrier.
