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.

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!

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.



App still crashes. More specifically when trying to view my current video mail message.

Z4 Mobile


I love this application because I'm a hard-of-hearing person. This works tons better than the VP-200 because, as the name suggests, Z4 mobile means that it can be carried out with me anywhere with wi-fi and/or 3G (or 4G in some areas, but don't know if iPad2 works with 4G). It's also great to keep in touch with other deaf and/or HOH (hard-of-hearing) people across the globe. Keep up the GREAT work, developers!

Update: Thank you very much for having this start-up in landscape mode! I enjoy videos and using apps in landscape mode as well! =-D

Edit: I think there's a bug when using the program: When the status says "Network not available" when you first come out of wifi zone and then come back, it won't go back to the previous screen, and then I have to re-install the program. I found out that I lost some contacts after re-installing the program. Please fix this. Thank you!
