If you have the "turn-on when driving" setting enabled, then our app will acquire a CPU wake-lock that keeps it running (this is not a big drain on the battery, about 1% per hour). Every three minutes we'll poll the GPS to see if you're driving and then start the application up if GPS indicates your speed is above 10mph. When it starts up it'll also notify you that it started up by speaking aloud to you.

If your phone is entirely off (and not just sleeped/screen locked) then there's nothing we can do about that... :)

Also if you have more questions, start a new comment thread in this post- the reply timeout makes replying super slow.
