While it sounds like it might provide hands-free texting, currently, Text’nDrive doesn’t — although the developer says that’ll change when support for texts arrives in October.
What the app does right now though, is make emailing a completely hands-free affair, by reading each incoming email and allowing the user to reply by dictating an email back to the app, which it then translates into text — kind of like having your own personal secretary. The app also supports Bluetooth devices, which should reduce garbled emails.
Even with the price slashed in half to $10 yesterday — the app was $20 when it was launched on Tuesday — it’s still a pretty big leap to take, so there’s a free version that limits the text-to-speech function to 45 words per email; unfortunately, it also drops the speech-to-text function completely, so there’s no way to test how well the app’ll interpret your speech.
