Places helps you build beautiful maps of your favorite cities. It's as simple as adding pins to a map and writing your notes for them. Sharing your maps is as simple as sending your friend a link (your friends don't need to have the app; maps built with Places are beautiful on the web too). It's really useful as a lightweight travel planner/journal, and also great when you have a friend visiting your neighborhood and you want to tell them where to go. It's a small, simple tool and it's completely private and free - no ads, obnoxious Facebook logins, or in-app purchases.
