Field Trip is that other project from Google's Niantic Labs. Sure, Ingress gets all the attention, but Field Trip is pretty cool too. This app presents cards with information on nearby places of interest as you go about your day, and now it's even more convenient for Android Wear users—place cards will simply show up on your wrist. Neat.

Here's the changelog for Field Trip v2.0.8. It's heavily watch-oriented.

• Explore the world with your Android Wear watch!
• Receive and view Field Trip notifications directly on your watch.
• Start Field Trip searches for nearby cards directly on your watch.
• Minor bug fixes.

So now you'll get Field Trip notifications on Android Wear, allowing you to see basic info about the featured location. You can also start the app manually on Wear to see nearby cards. On phones you can initiate a search from the card to get more information. That same functionality is available on Wear, but it triggers the search on your phone.
