This would be the perfect app except for two small things: local documentation on its use (not that it's pretty self-evident after a few minutes of fiddling, but still…), and the red "close" button on the app window does not work. The close button not working is a pretty glaring error. Other than than those two critiques, don't let that stop you from buying this app. It really does work exactly the way you would expect it to. It'll verify the MD5 or SHA256 and many other common hashes in a couple of clicks. VERY CONVENIENT AND USEFUL! I would give this app five stars if not for the two small critiques that I mentioned at the beginning of this review.

This app works just like it should. I never knew how to verify a checksum until I was pointed at this App on the download page for MAMP. Thanks! PS: It might be nice to have a short explanation of how to use this App in the google doc "File Hash Support". It's a bit sad to get pointed to that empty page...
