(My) Places is an app you may need to remember places.
Basically, you use the MapView to navigate to a place (which will be you default place if your iDevice has GPS functionality) and you can remember this place and even display it along with your own position in order to get to it.
It can be useful whenever you park your car in a very unusual place and you struggle with getting back to it.
Now with iCloud! View your Places on all of your devices! Refresh are automatic and usually take a minute or less.
Now with an estimated distance either to the detected user location or to the center of the map.
I am planning to add a share functionality ASAP.
Triple-tapping a point or long-tapping it will readjust its corresponding pin in CoreData.
