I used Field Trip for a while and really liked it when walking around in an unfamiliar city. As you say, as you went along, it would point out interesting facts, landmarks, etc. Then I noticed that its focus seem to change to "You're near Hardees! Here's a two for one coupon!" I deleted the app and never tried it again.
