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.

### 1/5 — Caller Cannot Hear Me

*2026-08-19, version 4.5.0*

My husband and I tried to fix this problem and couldn’t. I have deleted the app.

### 5/5 — Deaf

*2026-08-18, version 4.5.0*

My hearing clarity has gone. If I did not have the close caption I would be lost. Thank you so much

### 4/5 — Floater Icon went missing.

*2026-08-18, version 4.5.0*

My Email to support was answered quickly. 
They worked with me until my problem was solved.

### 2/5 — I need help

*2026-08-16, version 4.5.0*

The time it takes to reach me after the call is made lacks a lot in my opinion.  I had my wife call me and i waited and waited to the point i called her back to see if she called me immediately.  Of course was her response.  Nothing.  I think this may work if there’s assistance but I’m having trouble locating it so here I am frustrated.

### 1/5 — Phone heating up

*2026-08-13, version 4.4.8*

When I was paying for Innocaption, my phone would heat up after a few minutes and I would have to shut it down

### 3/5 — Inconsistent

*2026-08-12, version 4.4.8*

I would love this app if it worked for every phone call going and coming but it does not for me. I’m a new user, so still trying to figure it all out.

### 5/5 — Interesting app

*2026-08-08, version 4.4.8*

This call captioning device could be very useful to the hard of hearing. The set-up is a little scary at first but it is just part of the process. I hope this helps me fro asking my wife what people have said even though I had my speakers turned on

### 5/5 — Bonnie

*2026-08-07, version 4.4.8*

I am severely hearing impaired and cannot hear on the phone. I have a surgical implant that  is helpful in connecting me to my hearing aid, but I have very poor sound recruitment without my hearing device. 

I am wildly grateful for the use of Innocaption, as is my family.  My kids always ask if my Innocaption is working for me.  Then I say “yes!  Of course!” Then they know we can chat. 

Thank you for the creation of this incredibly helpful hearing device.  I would be lost in the wilderness without it.  

Many thanks and
Best regards

### 5/5 — Hear

*2026-08-07, version 4.4.8*

I can hear through my hearing aids and also read what they are saying!

### 4/5 — Lose connection

*2026-08-05, version 4.4.7*

Although I like I can see what we are saying at all times. I am sitting inside my home and talking to someone and InnoCaption would disconnect. I hope it doesn’t happen anymore it only happed once.
