TapGuid 3.0

TapGuid offers an easy and minimalist way to create, send and share GUIDs on your Android smartphone or tablet. A GUID (or UUID) is a globally unique identifier, a large number that is unique across both space and time, kind of a unique serial number that can be used on any item in the universe.

TapGuid is very easy to use: simply tap the New button on the bottom of the screen to generate a new GUID. Tap the Settings button to cycle through all available display formats (standard, digits only, registry, Base64, etc.). Tap the Copy button to copy the GUID to the clipboard in the current format, or the Share button to send it to other apps. (Try messaging a strange string of hexadecimal digits and letters to a non-geek friend or family member.)

For each unique identifier, TapGuid fills the screen with a different color shade, that is computed from the value of that ID! If you like the color, long tap the screen to copy its code and reuse it in other apps or sites.

That's it! TapGuid doesn't waste your time, battery and resources, and only requires 0.00005 GB of storage. It's also completely free, has no ads, and requires no Internet and no permissions whatsoever.
