Z5 Mobile – The best video call experience, wherever life takes you.

With Z5 Mobile, the industry’s premier VRS (Video Relay Service) app, deaf and hard-of-hearing individuals can make and receive videophone calls anywhere using Wi-Fi or a cellular data connection. And now we’ve completely redesigned this app to bring you the top features and experience in the industry.

Recent updates now include text chat, the ability to share a follow-up number with an interpreter straight from your contact list, and even the power to block unwanted callers. Our users love our intuitive user interface with a choice of two themes and the sort your contact list by first or last name. You’ll also enjoy the ability to quickly review, record or delete your Video Mail greeting from your phone. Even when you're not using the app, you can now receive full-screen notifications at the moment a call is incoming.

Z5 Mobile still has all the great features users have come to expect including Number Lookup, powered by Google Maps, to help you find phone numbers and conduct map searches without having to leave the app. No matter where you go, there’s no better way to keep in touch!

Good but horrible connections

I had this app for about a month and had no problems but issues appeared just a few days ago. My iPad and iPhone had NO WiFi connections at work. At first, I thought it was the modem at work but when I made a call through my iPhone (using data connection), I immediately saw LTE icon switched to Z5 icon. When I was done with the call, the Z5 icon changed to WiFi icon and then back to LTE icon. I tested my iPad by uninstalling the Z5 app and PAH! My iPad’s WiFi works!! I shouldn’t have ported from Sorenson to Z5. 😑 But the ZVRS interpreters were way better than Sorenson. 😐 Please fix or I’ll port back to Sorenson!!

Still disappointed

Here’s my problem. You guys have updated this, and while it looks great, there STILL is not a flash alert built into the app. I feel that this is not fully accessible for deaf people, because there’s no visual flash alert. Not everyone holds their phone all day to feel the vibrate alert. When I called ZVRS to complain about this, I was told to check the settings in my phone, blah blah blah. Then I was told to take my phone to the store to have it looked at. That was an insult. ZVRS should have the common sense to include a flash alert IN THE APP.

With this being said, I’m staying with Sorenson, because they have myRumble, which gives me the option to CHOOSE my flasher and vibrate. The choose to be fully accessible to their customers.

This could be better.

It’s so frustrating when I get emails of missed calls, important calls I’ve been waiting to get and the app doesn’t even notify me when someone is calling. My notification is on, all on. Then as soon as I check the app, my missed call list is empty, my video mail is empty. What??? I switched to this from Convo??
You better fix this because no way am I going to continue missing important calls and not get anything in the sign mail. Come on, y’all said you were better this time :(
