It makes data management easy and fun.

The simple design and quick performance really makes this my go-to data management app. I work in video production, so with only 500 GB of hard drive space, I end up filling it up quick with files well over 10 GB in size. This app makes it easy to pinpoint the “culprits” and allows me to Open in Finder to either delete or down-convert to a smaller size. I wish they made the same thing for Windows because I use both Mac and Windows for my work, but from the quick scans to the list of the largest files to the easy-to-explore way it organizes data, this app seriously has transformed how I SEE data, and also how I manage it. So far this is my favorite app on the Appstore. If you need a great way to manage data, get this one. It’s awesome.

Finally I have some free space!

This has to be the first app that actually gets the job done. it shows a chart and long list of documents, organized by file size, to show what is really taking up your storage. Within 15 minutes, I deleted some old movies and large size game apps, and I saved 34GBs of space. As Wayne from Wayne's World would say "Excellent"!

Great Data managment, however not full version

I normally stray away from "cleaning" apps and stick to manually keeping my drive clutter free, but I tried this app on a whim and was very impressed with its ease of use and graphical interface. I especially liked the Purge Free Disk Space feature. Unfortuantely, and this SHOULD be a disclaimer, the Purge Free Disk Space feature is not included with the Apple App store "pro" version and is only available from the Pro version off of Nektony's site. Luckily after contacting customer support I was supplied a license key for that version after I purchased the app store one. They explained to me that the Apple Store version does not have this feature because it doesn't align with Apple's software requirements.
