Buddy Finder is an awesome location sharing app. It allows you to see your friends locations and for your friends to see yours. You can turn it off at any time. Its great for seeing friends that are near so you can meet up or hang out. Its also great for meeting in a crowded area or to meet someone for the first time. You can also leave messages for your friends to see when they are close to the location you posted it in. You can also send private messages within the app.
