The NZ Relay app is a free Android application perfect for people who are Deaf, hard of hearing, deafblind, or speech-impaired and want to make and receive phone calls on the go. This app is a great solution for those who struggle to make phone calls on their own due to hearing or speech difficulties.

The NZ Relay app offers two types of calls: Text Relay and Captioned Relay. Text Relay enables users to text their part of the conversation to a relay assistant, who will speak on their behalf and text back the responses of the other person. Captioned Relay allows users to speak and listen on a phone call while reading captions of the other person's responses.

The app and the calls made through it are completely free, but it is important to keep in mind that using the app will consume mobile data or internet connection. Overall, the NZ Relay app is an excellent tool for those who need assistance with phone calls due to hearing or speech impairments.
