You can use the app to make outgoing SMS messages and calls from your Google Voice number. What's more, this app improves the mobile experience of Google Voice in a number of ways.
The Apple Google Voice app integrates seamlessly with your phone's native address book, making it even easier to call or text with your Voice number. Voicemail transcriptions are now available, and the app will highlight individual words during playback just like your favorite karaoke song. It also lets you take advantage of Google Voice's low-priced international call rates, starting at only $0.02/minute.
