Phone heating up

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

Inconsistent

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.

Interesting app

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

Bonnie

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
