Detect duplicates, spot similars, and wipe them away. Gemini 2 finds duplicate files with laser precision. Tech reviews agree:

"Gemini, our favorite duplicate file finder for Mac, got a big update today that modernizes the interface and improves the file scanning algorithm so it can find more duplicate files even when they’re not named the same thing."
– Lifehacker

"I’ve been an active user of MacPaw’s Gemini software since its inception, and Gemini 2’s release today has made me fall in love with it all over again. In just the initial scan, Gemini 2 found more files and more places where I could intelligently clear and save space on my Mac."
– 9to5mac

Gemini 2 has all the powers you need to free up space on your Mac:

Spots Similar Files

Selects Them Intelligently

Spots the differences between files and points them out
Remembers how you pick files for removal and starts doing the same

Deletes Them Safely

Moves files to the Trash and lets you restore them, if needed
Or, deletes duplicate files right away — if you so choose

Customer Reviews

Best Duplicate manager

It is one of the best App in Mac App Store

Love the app

I just got this application , and I had so many duplicates and it was able to find and clean then up. I am so happy with this application

Itunes Integration is Broken

I’ve used the orginal Gemini which was very good. This version is good, but the iTunes integration is broken. It seems like the product is not a polished as it should be for version 2.3.2. For example one cannot restore defaults so if you select not to open iTunes you cannot scan your itunes libaries without reinstalling Gemini 2.
