The new standalone UberEats app is a dedicate mobile service that ensures that you won't ever again order a pizza when what you were trying to do was order a car to take you to the airport.
UberEats has been around for a little while now, but it was unfortunately crammed in with the regular Uber app. Not only could this create confusion and inefficiencies, it also made for an interface that was slightly more cluttered than usual, which is why the solo UberEats app is so desirable. The app includes an Instant Delivery menu that only includes items that you can get in 10 minutes or less, perfect for when you're starved for time.
The UberEats app is being tested in Toronto, but the concept is smart and simple enough that it's likely to be rolled out elsewhere. It's an example of how apps are becoming increasingly specialized.
