Gorgeous design, but inflexible and uninformative

Geminini is clearly designed and engineered by people who know what theyre about. The user interface looks so good, and animates so smoothly, you feel like youre in front of a really stable, really fast application.

But Gemini turns out to be useful only in a narrow slice of of use cases. It works great if youre only expecting at most a few dozen duplicates. If youre expecting more than youre willing to sift through manually, then Geminis only time-saving option is to automatically discard files based on their dates. And discarding better be all you want to do. You cannot use Gemini to move duplicates, or rename them, or do anything with them other than delete them. If you were looking for a tool that could become a valuable part of a time-saving workflow, Gemini isnt it.

And even supposing youve used Gemini to delete some duplicates, you still dont know if all the duplicates are really gone. This is because Geminis duplicate detection algorithm is a mystery. Does it look only at filenames and sizes, or does it actually compare the content of files? Both? Who knows? Geminis Help menu will only give you an FAQ and a 13-page user manual that offer no description of the algorithm whatsoever, and the options found in the preferences window offer scarce clues. When you point and shoot with Gemini, you wont know what youll hit and what youll miss.

Before purchasing Gemini, you should read through several other more positive reviews. There are hundreds of them. See if those people were able use Gemini to do almost exactly what you want to do. If you cannot find reviews that describe your particular use case, then Gemini probably cant help you.
