This is not an ad. My wife sent me an invite and the app is free.
The reason that I post it here, is that this app might relieve many from texting while driving (a deadly hazard for all us cyclists).
The app converts your iphone into a walkie-talkie so that you tap the screen, then talk, and it transmits a voice-text message to your selected recipient(s).
This seriously could improve highway safety (esp. for teen drivers) and all others who share the roads!
