We are pleased to announce the release of version 2.0 of Contacts Cleaner. The two major improvements made in this version are faster processing of the address book and improved matching of duplicate contacts.
Since releasing Contacts Cleaner I have been surprised by the number of address books that have 10,000 or more contacts in them, often with the majority of the contacts being duplicates. It has been a challenge to find and merge duplicates in a reasonable amount of time given the modest processing power of a phone. I’m on the 4th version of the find and merge algorithm, and this version seems to be pretty darn good. The customer feedback on processing speed for version 2.0 has been overwhelmingly positive.
With respect to duplicate matching, one constant source of duplicates is Google Sync. To make matters worse, Google Sync tend to put the first and last name in the last name field of a contact. With version 2.0, we have changed the duplicate match algorithm to correctly recognize these cases of duplicates.
Enjoy!
