This is a very simple app that lists your contacts in order of most recently added.
The main purpose is to make it easy to find that new person that you know you added recently but just can't remember what they were called. No more scrolling through your entire contact list trying to spot the unfamiliar name!
Your contacts are divided into those that are associated with your primary account, and "others" (which could be hotmail/twitter/facebook etc).
A handy checkbox enables you to toggle between the two views.
The app can occasionally get confused when existing contacts are merged: sometimes the merged contact will appear at the top of the list as if it were newly added.
Unfortunately this is a limitation of the Android contacts system, but happens rarely enough that it shouldn't detract from the overall usefulness of the app.
This app is based on some Google sample code, with subsequent proprietary modifications to add required functionality.
