Gemini: Meet The Gorgeous New Duplicate Finder From MacPaw

MacPaw is at it again and has released a brand new app to the world: Gemini, The Duplicate Finder. The folks over at MacPaw are no strangers to the Mac ecosystem, and have released some greats apps in the past, most notably CleanMyMac.

Although not a revolutionary concept, Gemini takes a beautiful new approach to finding duplicate documents on your Mac, with a stunning interface and some fancy animations. Head on past the break to read more.


The simple opening screen

When you fire up Gemini you will already get a decent sense of the level of detail you can expect in this application. The only option you have is to upload a file for it to scan, and it gives you the option to click the + button to open Finder and chose your files, or simply drag and drop them onto the window.

Show Scan results option

After some pretty animation to keep you occupied while your files are being scanned, you are able to show the results and move onto the core functionality of this app: removing duplicates.

Selecting Files

Now is when the real fun starts. Once you’ve chosen to progress to show results you are presented with an entirely new screen displaying all your information regarding your scanned files. On the left is the upper hierarchy, showing ‘All Files’ and then split into the separate sub-categories such as Pictures, Music and Other. All the files from the categories are showed in the middle vertical bar. Here it shows you how many copies of each specific file there are, and giving you plenty of options as to how you want to order the files.

File preview window

What is incredibly useful is the right half of the app, which shows a preview of the selected file. This makes a world of difference; giving you an idea of what files you are working with, otherwise if the file wasn’t named correctly you would have little idea what you’re deleting. Below the preview is where the source of the file is saved, allowing you to decide which version you want to delete (hovering over the file icons, such as in the bottom of the two images, will reveal more information).

Now that you’ve got an idea of what kind of files you have duplicates of, its time to start trimming the fat. There is an Auto Select feature that will chose the files that it doesn’t think you need, and it will only apply this to the category you are in/ However out of over 30 pictures, it decided to only auto select 3 of them. So manual input is certainly needed, which is a good thing I suppose because you wouldn’t want the program selecting too many items and deleting stuff you may want to keep.

Some files can not be removed


List of all files selected for removal

Having selected all the duplicate files you want to remove, with a handy iTunes-like display up top showing the number and size of selected files, you click the Remove Selected button. You are then presented with a pretty ‘receipt’ with all the files you’re planning on deleting. You can review your selections and easily remove any if they accidentally got put in there.

Shredding your duplicates

After clicking remove you’re finished, and your files will elegantly slide into the shredder and out of your Mac – or rather into the Trash awaiting your emptying.


You can see from the numerous screenshots that this app is beautifully designed, which is always a good measure of the effort put into the app. Fortunately, Gemini lives up to the expectations set by the design. Sure there are other apps out there that offer similar services, yet Gemini remains a simple, easy and effective application that’s hard to beat.

Gemini removes all unnecessary elements by finding duplicate files on your hard drive. It may have some downsides, such as the inability to remove certain files in Apple applications, yet I would go as far to say that Gemini is the AppZapper of duplicate finders. You’re paying for the wonderful experience and convenience of having such a great app – and I believe at $4.99 its reasonably priced.


A beautiful way to find and eliminate duplicate files on your Mac.

  • The UI is, face it, just like iTunes (down to the song track box!): cluttered and an eyesore. I honestly can’t see how this can be “good design”, really. The multi-colored pie chart at the bottom left-hand corner is superfluous, especially under the iTunes layout, and so is the “Tweet” button on the cleaning Trash window. Why on earth would you tweet about cleaning up duplicate files?

    I’m sure the app runs fine and works really well, but I wouldn’t call it beautiful even if someone paid me to do it.

    • Agreed. Click on the top then click to the bottom. It really could do with some work on the UI. The shredder is a nice touch if you’re into that kind of thing but this reviewer’s entrancement with the UI surprises me. I struggled to find the right area to click to do what I wanted the first few times.

  • Or just use Singlemizer – a great if not better app with a not so nice interface. Found it on the AppStore a few days after Gemini came out.

    Looks nice, but not nice enough to buy it if there is a good and free alternative utility.

  • While i’ll never use it or need it, I bought it anyway just to stare at that UI – I really “just want to lick it.”


  • I can’t remember when I’ve had so much fun with a utility app! 10/10 for sure. I think it looks sleek and uncluttered compared to many other duplicate finding apps, DupeZap to name one. Like you said, it’s actually fun to do some house cleaning. I haven’t been this excited about an app in, well, I can’t remember.

  • nice interface, but has the same limitation as the duplicate finder in Drive Genius – you can’t search across multiple drives.

    • Hey Gaz, you are not right.

      Gemini allows you to scan multiple drives in a same time, just select them by holding shift and clicking over them, simply drag them all to Gemini’s window, and that’s it.

  • No doubt Gemini is good option to find duplicate files in Mac. But, except duplicate files there are many other reasons behind your slow Mac like accumulation of cache files, log files, universal binaries, system junks, language files in Mac with the passage of time. So, to get rid of these files one should try a software that can clean all such clutters from your Mac. I know about Stellar Speedup Mac which is an amazing tool for cleaning all such unwanted application and files and improve Mac performance.
