• Scan your odometer — snap a photo in Add Mileage and the reading fills itself in (processed on your iPhone, never uploaded) • Pace alerts — one notification the moment a new reading puts you on pace to finish over, with the cost and the daily pace that fixes it • Add Mileage now shows your last odometer reading up top, and so does the widget
