You might care the most about Uber's app for customers, but the drivers' app matters a lot, too -- after all, you won't get a ride if cars aren't waiting for your request. Appropriately, Uber has revamped the driver app to make it far more informative and give workers more reasons to offer you a lift. The software provides a real-time status feed with notes, tips and (most importantly) extra chances at making money. It also has an always-available activity map that shows drivers where they're most likely to get customers, even when surge pricing isn't involved. Earnings and ratings are easier to understand, too. You may never catch more than a fleeting glimpse of this app, but it could make all the difference if you get a timelier trip home from a driver eager to make a buck.
