How do i get every user that installs my app but without asking the user to register anywhere also sorting by every time it joins (opens) the app. Any help will be appreciated.

@Stefan. Congrats on your 100th topic. But I fear you've been watching the Yoda channel too much. Unclear your question is.

When user opens my app i want to take his location and sort them in a list by time they joined the game and display them on maps.
