Clean Out Duplicate Contacts
Somewhere between reloading ROMs, going through new phones and adding contacts in last name, first name versus first name, last name order we all get a lot of duplicate contacts. In the past I’ve cleaned this by using software on my PC. Thanks to zaijian of XDA we now have Contact Cleaner which is a simple way to remove duplicate contacts. If there’s an exact match you can set it to automatically remove the dupe (I had 80 exact matches). It also tells you about near matches (like two of the same contact but with slightly different info) but I found this feature a little more confusing to use but it’s still a good tool to see where my near dupes are. All in all, it’s a simple app to use and it works. For anyone that used DupeDeDupe for this in the past I’d love to have your opinion on which is better.
Contact Cleaner can be downloaded here. Thanks again to zaijian especially for cleaning out 15% of my contacts.

zaijian Glad you liked it! If you have any suggestions for UI improvements or feature enhancements, i’ll gladly take them!
I admit the keep/delete/merge tool isn’t that great but I just wanted to get the app out the door. Classic case of 10% of the application taking 90% of the development time.
zaijian @Keith Good idea with the calendar version, I can do that as well (most of the code should be the same). I did have that problem a few times after syncing.
Keith Yea, that is why I suggested it. Sometimes when I flash a new ROM, I get duplicate calendar entries. Now that is a royal pain to clean up. 
zaijian Check the XDA thread again, i’ve updated the app to remove duplicate tasks and appointments as well as contacts.
[...] finally Contact Cleaner (which removes duplicate items and that now includes appointments and task and a better tool to [...]
It would also be nice to see something like this for calendar to remove duplicate events.
