*** 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.

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.

Review by jskelley714

Caution: Cancellation messages will be sent for every deleted iCal entry. - I just got done explaining the cause of a flood of cancellation notices to over 900 people. All entries from 1/1/2009 to today that were either merged or deleted caused a firestorm of deletions and follow on replies explaining what had happened. This included all my customers. Even worse, all my former prospects that didn't buy our products were very confused by a cancellation dating back 2 years.

Review by Admiral Boom

Colors gone, events repeat forever - All my colors disappeared, a bunch of yearly events now repeat every day, the app froze up midway through the process as well. My calendars are now worse rather than better. At least I have backups and I’m only out four bucks. Disappointing.

Review by @seabirds

Not very impressed - I purchased this app based on a recommendation from the Applecare tech guy. I fully understand that they are not responsible for the quality of the app as they did not write it. My problem was that I had many duplicate appointments after transferring my mail from Outlook to the Mac calendar. I did the download while my Mac guy was viewing my screen, so I think I did what I was supposed to do in installing and running it. It is actually very simple and difficult to make a mistake and I am no novice in software use. I suspect there is a bug in the app as after I ran it, not only did it not delete duplicate appointments, but it multiplied them, actually scheduling ALL of my appointments to occur every day out to the limit of the calendar! With the help of the tech, I was able to delete all appointments in the calendar and from the cloud, restore the calendar to what it was earlier that day. I would say that it may have been something in my system that caused it because no one would buy it if all had my experience. I would recommend that the designers take a look and fix it.

Crashes at boot - This does not fix a corrupted calendar file. It crashes at boot if you have a bad calendar database. I’d love to get a refund as this product does literally nothing for me.

Version 1.7.2
Review by Eric Postpischil

Completely failed - Calendar Cleaner failed completely for me with Calendar 8.0 in OS X 10.11.2. It hung, and eventually there was an audio announcement that an error occurred, but no error message appeared.
