Application is okay and works as advertised. But their constant (almost weekly) updates for minor things smacks of updates-to-promote-their-product on this site. It is really annoying and, I'm assuming, a waste valuable time, to constantly update without knowing how crucial they are.

We believe in constant development and if we have improved and better code then why not make it available to our customers? We are sorry to hear that you consider always having access to the latest and greatest version of our application is annoying.

For most of our customers running Duplicate Annihilator is not a very frequent task since once the library has been cleared it is not an issue for a while and therefore they should not really nede to update until they intend to run the application again. But for our new customers we want to make sure that they have the latest version available. We really don't see the point in keeping good stuff away from our customers.

Once again, we are sorry to hear that our intentions to keep our customers updated with the latest code is considered to be a waste of time and annoying.

In "unregistered" mode you can scan up to 500 photos. This is certainly sufficient to make a buying decision.

It is a small program and it runs quickly and quietly - nice!

Options for the disposition of duplicates are useful and understandable. I was looking for one more thought, that of moving the photo to the system trash. Instead, it remains in the iPhoto trash and your only choice is to leave it there or delete it in iPhoto. This was never something that I liked about iPhoto and it is not something that Duplicate Annihilator should be faulted for.

I found changing the comments to "duplicate" or "original" as a good alternative to deleting photos. It gives you a chance to review your photos one more time in case there is a problem.

The "Find and annihilate duplicates" button is somewhat understated but that is a style opinion. It could be bigger/more colorful.

This is a great time saver - I think I'll buy it!

@ERNESTR3096 Duplicate Annihilator is very specialized in iPhoto related problems which other softwares don't such as detecting imported thumbnails and faces which is quite common when migration or recovering iPhoto libraries.

It also detects missing photos where a photos is visible in the iPhoto browser but unavailable when trying to look at it.

Another asked for feature is the ability to find corrupt images to clean the library even more.

If you have further questions please feel free to email us at propaganda@btattoo.com

It's a one trick pony. But it seems to do that trick very well. I'm not sure how realistic it is but I took off half a star for speed or lack thereof - it takes around 3 hours to go through 11,000 pictures. I feel it ought to be faster, but I've no idea if it could or how it could be faster.

It's easy to use, is explained well and the family licence is very cheap for what it offers.

And it has never fallen over on me. I suspect the dupes that creep in are due to syncing pictures across 5 Macs.

A software developer by trade, I often write my own scripts to automate tedious tasks in order to have the best control over the end result. After many hours of working on my own and pulling in several open source alternatives, I purchased Duplicate Annihilator for less than $10. Not only has this program identified my iPhoto duplicates MORE ACCURATELY than what I produced after hours of manual and script work, but it did so with no supervision. An excellent software and great support. I highly reccomend this product to anyone who wants to enjoy their photos instead of organizing them.

Ok, I am an OS X noob but when I tried this app it told me I have no duplicates in my iPhoto library. Altough I am 100% sure it has tons of duplicates!
As a test I duplicated several with a different name and it still didn't found those.
It does search thru the library though - it scanned the correct amount of photos I have (+5000).

Am I doing something wrong?

Before the update I had 0 duplicates with DA.
After update I have 88 duplicates, none seem legit.
Update does make it a tad faster though so that's good.
This app has always been pretty solid so please fix. Thanks

Thank you for getting back to us and providing us with some sample images. The problem has been isolated and fixed in v4.6.1, released today.

We have a test suite of about 500.000 images which we run each new version through and apparently none of them had this issue, we apologize for this.

I've tried out a few apps but this one is the best for me.
There are many option and it works very fast!
Where other apps failed to recognize the difference between a real photo and a thumbnail this app performed the job 100% well :)
My iPhoto library contains about 45000 photos.
It's also very affordable so I've bought a Family Pack.
A few minor things are lack of translations (I live in Belgium) and the UI coold be better in my opinion (but that's a personal thought).

Bought and used the Aperture version. Bottom line is that I would recommend this.

But:

— It is not an annihilator at all. It finds suspected duplicates and tags them. That's all. You have to do the deletion.

— The speed. It takes time. But these things do.

— The instructions are incomplete. They do not mention that after the application finishes, you need to do things in Aperture to find, evaluate and delete the photos.

— The Aperture version does not work unless you (with some risk) rename your iPhoto library to be recognized.

I have no idea how accurate it really is. I deleted 3,000 dups. The ones I checked were real dups, but I cannot attest that I did not delete something unique.

It was advertised to be packaged with an orphaned thumbnail remover. Maybe that is built into the app now.

Again. Seemed to do the job well at low cost and in only a few hours.

Overall comment: SLOW! I can't believe how slow this program is and I'm running it on a Macbook 2.4Ghz with 7200RPM hard drive, 8gb RAM. Just to sort 20'000 photos takes 3 days! And, worse of all, it completely neglected some duplicates despite using it's "Magic Mode" when the file was identical in name.

Would not recommend. I saw some reviews which gave it 5 Stars saying it's fast - I tried it also on my iMac 3.06Ghz and it takes just as long, just minus a few hours! Would not recommend.

There are many factors that affect speed so if you experience problems with performance then email us directly and we'll try to help you. Example: on one of our 2.0GHz MacBooks it takes about four minutes to process 1.000 photos.

Magic Mode will not detect duplicates based on filenames since filenames is nota good wary to detect duplicates. Example: the same camera could generate trio photos from two different occasions resulting in two separate images using the same filename.

If you encounter problems with undetected duplicates then email us directly for a speedier response and most likely a solution.
