Description
Calculate and compare the hash code on your mobile phones, conveniently!
It supports MD5, SHA1, SHA256, SHA384, SHA512, CRC32, and more in the future!
It is a material-design application, so it looks really nice!
And, you can just do it by selecting it in the share(or send) menu of file managers!
