Field Trip is a free app for Android and iOS that runs in the background on your phone and will pop up a card with details about your location when you get close to something interesting.
It's a great way to learn something new about the area around you, from history to local eateries and more. It gets information from users and from multiple sources and databases and is a lot of fun.
It can be useful for students to learn something new about their home and neighborhood. Teachers can use it to find interesting things about an area before taking students there.
I had fun walking around my home town and using it on some trips to find some cool info.
