"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."

Customer Reviews

Useful product if you work in sales and are always researching and downloading files.

I work in sales and I am contantly downloading exhibit designs for my work and saving things. By doing so, it uses so much space on my computer so once I have cleaned my mac with ‘Clean My Mac 3’ ehich superb to remove junk, cache junk and everything else from all folders, I then use ‘Gemini 2’ to remove any duplicates and it said I had about 7.9gb of duplicate stuff. Anyways, my mac is back to being fast as usual!

Much Better than previous version!

Gemini2 is neat, simple and very smart duplicate management tool. I used most duplicate management tools ever released on MacOs, I can recommend Gemini to other persons without any hesitation. Yes, totally sure, there are more powerful tools for the same purpose, however, they are usually powerful, but not so good for easy-to-use. Gemini is Powerful, but Simple, Simple, but Easy-to-Use Tool. You must be satisfied!!

Works well

Seems to work pretty well. I tried a freebie version first to see if I’d like it and so far so good. Ive been sitting here for the last hour pulling up a zillion duplicate files i didn’t even realized I had. Freed up a lot of space!
