Faster GPS while driving. On the way to a customer, the phone sends its location every 5 seconds using high-accuracy GPS, instead of the slower rate before. That's what lets the customer's tracking map show the car moving smoothly. The driver page sets the pace. The hosted page tells the app how often to send. We can change it with a page update, without a new App Store build. Battery saver when parked. When the driver is stopped, for example at a customer's door, it drops to lower-power location about every 80 seconds. High-accuracy GPS is used only while en route and moving. Same idle shut-offs as 1.2.0. Background location still stops after 20 minutes idle on shift, after 3 hours en route, or 14 hours after the shift starts. Works with older versions. Old driver pages still work in it, and it works with older hub versions.
