Easy Hash Compare is a free and easy to use app to compare the MD5 hash values of two files on your Android file system. It will allow you to know, with some certainty, that two files are equal.

Simply select two files from the filesystem and voila! MD5 hashes and an automatic comparison.

You can download Easy Hash Compare from the app store here.
