iOS: You probably have a set number of places you go to on a regular basis. ETA is an app that shows your current estimated drive times to those places from your current location.
When you first open ETA, you'll need to go in and add your favourite locations. After that, every time you open the app, all you see is a list of your hand-picked locations and the amount of time it will take you to get to them. If driving isn't your thing, you can swipe the drive time icon to get estimated walking times as well. It's simple, but it's a really nice way to glance at travel times without messing around with a map.
