The Z has released the Z5 Mobile for iOS. It’s available at the Apple App Store; Mac, PC and Android versions are in the works.

The app is designed to make it easier for deaf and hard of hearing people to communicate with friends, family and business contacts — hearing or deaf — while on the go, says the Z CEO Sean Balanger.

Some features involve improved management of customers’ contacts. An integrated address book gives users to access phone numbers stored locally on their iOS device, as well as those in their online Z profile account. With the new “Favorites” feature, callers can designate contacts they use most, similar to using speed dial.

Customers can also set up avatars (icons or pictures) for contacts for further customization. Favorite features like Video Mail, Digital Whiteboard, VCO Plus and HolaVRS continue to be available, not to mention access to the industry’s best interpreters.

The free app will allow deaf and hard of hearing people to make and receive point-to-point calls to/from any videophone, as well as make and receive video relay service (VRS) calls. For more information go to www.zvrs.com .
