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.

Best App ever with no monthly fees!

I used to need someone else to make phone calls for me. I am hard of hearing and it is progressive. On my daughters birthday, five of us went out to a restaurant. I could not hear any the conversations. I could read lips but sentences and content were indecipherable. I was isolated the whole nite - smiling when everyone else was amd trying to nod when it seemed fitting.
INNOCAPTION has amazingly opened the door to the hearing world! I used you avoid using the phone, and now I am so empowered that I enjoy even talking to Medicare! You can select a live operator or a technology driven computer program. InnoCaption has enabled me to read exactly what’s being said with 99% accuracy.
No more asking my husband or family member to help me use the telephone. It’s not a welcome request to ask someone to call the DMV or your insurance company for you. Now I can do it myself with crystal clear accuracy.
The I ocaption features were well thought out and leave you with more than a hearing person using the phone would. For example, you can retain a copy of a conversation. That helps you with recording old phone numbers, remembering dates and ID numbers, and remembering names.
For anyone who struggles with hearing loss and subsequently using the phone, get this app. You will wonder how do you survived without it I give it 100+ percent satisfaction.

Great App

I never leave reviews, but InnoCaption has been such a game changer for me, I felt compelled to do so. This is the third caption app I have tried and it has been so much better than the others. It gives you the option of using an individual to transcribe or automated assistance. The option of a human to transcribe is supposedly more accurate and the automated option is faster. I started using it with a human transcriber and then switched to the automated option. I found both to be accurate. The automated is very accurate and the only time I have any real problems is with numbers. It can get a bit confused with phone numbers and such but it is usually so fast and accurate that it is the only option I have ever used and was able to have a normal conversation without asking people to hold on while I waited for the captions. It is the first time in 20 years that I have not dreaded making a phone call. Also, the voice mail is so much easier than my last app. My last app required using a tree menu. Push 1 for this, 2 for that, etc. Transcribers have a hard time with those trees. InnoCaption lists the calls and you just pick the one you want to hear. No need to push a bunch of options trying to find the call you want. This has been a GREAT APP for me. I hope they keep it up. I would really hate to lose it.

Innocaption App lifesaver

I started using Innocaption about a month before Hurricane Delta 75 mph winds split a cedar tree in half which continued to slowly lean towards my house and a busy street as well as knocked down several large limbs and branches from other trees. It became urgent to remove the cedar tree asap. With no electricity to use my CapTel home phone, the Innocaption app service was a lifesaver in being able to contact tree companies. Thankfully, the tree was removed 1 1/2 days later. Without Innocaption, I would have had to wait 3 days when I finally got power to use my phone!! It is now a few years later and now I’m using the Deskview on my computer as well. I needed help to get it installed. Susie and their engineers worked with me every step of the way until the problem on my computer was resolved. The FREEDOM the Innocaption app gives me, as I run around town when family, Medical appts, etc. call, helps me not worry that I will miss a call when I leave the house where I use my Captel phone which I love at home. If I have no electricity, I have access to my cell phone to make calls through Innocaption. When I was in the hospital for a month, I was able to continue to talk to family snd friends. So I encourage everyone to give Innocaption a try by signing in the app to see if it works as well for you as it has me!!
