Featured in the “Essentials”, “Best of Mac App Store” in 2015, 2013 and 2011, “Get Productive”, “Get Stuff Done” and “Invaluable Utilities” editorials of the Mac App Store.

Over 500 reviews in the media including major titles like Forbes, TechRadar, Lifehacker, Gizmodo, MacRumors, 9to5mac, Macworld, TUAW, MacStories and many others.

Daring Fireball: “[…] Daisy Disk is my personal favorite for analyzing disk usage on the Mac. It’s a beautiful app. […]”

TechRadar: “[…] we recommend an easy-to-use utility called DaisyDisk. This app helps you easily find and remove unneeded files you may have forgotten about.”

LifeHacker: “DaisyDisk is a beautiful disk space analyzer. It’s the preference of many Mac users. […] DaisyDisk is very fast and very pretty.”

Gizmodo: “Deleting files and sorting out disk-space is one of those tasks most people dread, so I can definitely appreciate that DaisyDisk has tried making it as fun (and beautiful) as possible.”

MacRumors: “The new DaisyDisk 4 has a new, flatter design […], with bright colors, it’s able to scan drives up to 20 times as fast, and it consumes less memory when in use.”

9to5Mac: “DaisyDisk, chosen by Apple as a Mac App Store ‘essential’, provides a cleaner and more interactive circular interface for [visualizing Mac’s hard drive].”

Macworld: “For only ten bucks, DaisyDisk is a simple, convenient utility for every Mac owner, and it gets the job done well for less technically-inclined users.”

TUAW: “Daisy Disk is the perfect example of one of those tools that should be built right into OS X.”

MacStories: “While there are a few similar apps none of them even come close to matching the beautiful DaisyDisk interface.”

Beautiful Pixels: “DaisyDisk is a phenomenally helpful utility app for Mac. […] This is a really fascinating way to take a look at all the files and folders residing on your Mac.”

Notable features:
• Unique interface that makes it easier than ever to find and delete large useless files
• Unmatched speed of scanning – it typically takes only a few seconds to scan your entire startup disk (depends on your disk and CPU models)
• Integrated QuickLook for previewing file content
• Scanning multiple disks in parallel at maximum speed
• Real-time information about mounted disks
• In-app file deletion
• Fully supports Retina displays

Actually Perfect

I've been using DaisyDisk for a pretty long time now (> 3 years) and honestly its the best disk space visualisation tool i've used ever. It scans quickly and the results are clear and very well presented. I can't really think of a way it could be improved.

I usually wouldn't bother to review it but did a scan today to clean some stuff up and noticed a large amount of 'hidden' files. DaisyDisk showed a notice that it couldn't show what the files were, however, because, as an app store app, it couldn't request the appropriate permissions and directed me to download the standalone version. A lot of developers would take the opportunity here and double dip and charge you again but just took a download and it automatically transferred my license for free.. that is just a stand-up way of doing business.

It is a fast beautiful app that I consider to be fairly essential and cant recommend highly enough.


Difficult to use for larger disks

I have a 3 TB fusion drive and, although I only have 500 GB used, I still want to see what is taking up space. In this configuration, a 15 GB directory on the fourth level of the ring is so small it's difficult to get the mouse to hover over it. There are two things this app could do to be more useful for me. First, it could add a toggle to exclude free space from the ring, so the 500 GB of used space I currently have takes the entire circumference. Secondly, the ability to scroll/zoom in would be useful as well. Some view preferences in general would not go amiss. The app looks very nice, but the above and its complete lack of configuration make it mostly useless for me.

Edit: I have noticed the ability to click on a section in a ring to effectively zoom in on this area. I am increasing my rating, but still deducting a star because I think this is a bit unintuitive.

Thanks for your thoughtful feedback!

It’s true that DaisyDisk is designed to help you focus on the biggest files in the first turn, because removing them is the shortest path to the app’s goal – to free up space. This is achieved by giving small files less visual weight and occasionally even hiding them from view to reduce visual noise.

That said, DaisyDisk allows you to view the small files too, when necessary. To “zoom in” you need to click on the desired folder to change the current level of hierarchy and therefore the level of detail (linear zooming would not add more information because it doesn’t change angular sizes). Besides, on each level of hierarchy you can use the sidebar list which contains all, even the smallest files, and therefore always covers the use case you mentioned. The same goes for the case when free space dominates on your disk (btw if so, the problem of low disk space doesn’t exist :).

We believe that current design strikes the optimal balance. It’s optimized for the most important use cases and still covers the rest of cases. That said, we continue to improve it and at some point we may add more possibilities like the ones you mentioned. Note that we intentionally strive to minimize the number of options, by integrating the functions directly into the design and you use them naturally when you need them and without noticing, which is exactly how good UI design should work, in our opinion.


Very handy!

Have used this app multiple times over the years to both get a general sense of drive usage and drill down to identify specific unneeded space hogs for removal.

One idea/suggestion for an opportunity to continue expanding the app’s usefulness: consider exploring the addition of a “tree map” mode (in the manner of WinDirStat and the discontinued Disk Inventory X). The ring-based sizing is perfect for some use cases, but I find the tree map view to be an easier method of visualizing overall space usage across multiple folders. DIX still works when I need that capability, but I know that won’t last forever. Please consider it!

Thanks a lot for your thoughtful feedback! In fact, we considered the rectangular "tree map" back in the early day of designing DaisyDisk, and concluded that the circular "sunburst" map generally works a little better in most cases and for most people. The inherent downsides of the tree map is that it kind of overwhelms you with too much detail at once as opposed to progressive disclosure of the sunburst, and second, the tree map doesn't immediately show folders, only files, while the containing folders are an important contextual information to understand what the file is, and whether it's ok to delete it. That said, you're right that the tree map, when implemented properly, can work pretty well too. We'll think about it, maybe at some point in the future, when we will have other problems solved, the tree map can be a fun feature to add. Thanks! Oleg.
