*** Feedback from Users of Calendar Cleaner ***

"I adore Calendar Cleaner, by the way. It saved me the trouble of manually filtering through nearly 30,000 calendar records, dating back to 1999, to remove about 3,000 duplicate records that had been created by sync misfires over the last 10 years of Palm and Mac OS syncing." —Don N.

"Calendar Cleaner: LOVE LOVE LOVE this tool. It's saved me hours of headache and heartache." —Rich S.

"Just dropping by to say good job! it works great! I've been having some issues with a self-duplicating calendar event and it cleaned it up! Syncing now is normal and trouble free." —David C.

"Very nice tools! Great scan speed for iCal events!" —Jochen W.

Excellent App!

Keeps all your calendars in great shape. No problems here!

Good support from the developer

When I originally installed this app a few months ago it had some issues. I would click the button to have the discovered errors fixed, but when I scanned again the same errors would show up. After emailing the developer and bringing this to his attention, he got things sorted out. Now the app works great and I run it every so often to make sure my several calendars stay in good shape.

Good, but could do better

Good app for cleaning out most duplicates but doesn't get all unfortunately
