Ratings and Reviews
Another app that promised to do this left me with over 5000 duplicate contacts! This app cleaned up my whole contact book in seconds. Well worth the $2.99 in app purchase.
Do not waste your money!!
For contacts, it works as good as many other cheaper add on the market.
For calendar events is a totally different story. It is not the little money that it costs. It is the $1,000s of dollars you will waste in hours trying to clean up the 100s of duplicates it added to my calendar!! The best part is that it is STILL doing it. Every hour it adds more duplicates hence freezing your outlook. Those of us who need their inbox to make money are now out of luck until this monster stops or you disable your iCloud in your outlook which disconnects you from your office calendar. Beware
Clean duplicate contact application
Doesn't crash, limits duplicate merge / delete to 701 records per, but very clean, fast, in-app upgrade affordable, very well written, cleaned up 35,000 records in less than 10 minutes.
