I’m in love love love with this app

This app is awesome and so good!!! I’m loving the new updates to this app. No more clicking on the notifications to connect to the app during an incoming or outgoing call. It has been streamlined to where I just make a call or receive a call and the app does the rest of the work for me. This is a godsend for me as I’m more independent with the help of this service to handle or take care of my daily tasks.

Also allowing others to know it’s me calling from caller Id versus an unknown number they are not used to receive which would not have them answer the call. This is a great app thanks to the developers who worked tirelessly to make our job easier and enjoy conversations with family friends and businesses on the regular. Keep up with the good work. May You be blessed!!😘😘

High Call Volume Issue

I was in a middle of an important phone call and the captioner terminated the phone call due to high call volume. This is unacceptable and this issue needs to be fixed. I had InnoCaption for almost two years and this was never been an issue before. I use this app for important phones even to things for jobs and I am deleting this app for now until I see improvements. As a hard of hearing person who uses this app, please be wary of this.

All doesn’t work out of state

I travel for work and this app worked perfectly fine regardless of where I was in the US previously. Now when I am connected to WiFi I am told that I am in an out of service state. Why does this matter so long as I am calling within the appropriate working hours?If I call without WiFi the app works, but it’s a nuisance because WiFi calls sounds clearer. Please fix this, it’s ridiculous.
