Guys, if anyone's interested, my IV calculator supports 6th Gen games (X & Y), for Windows phone:
http://www.windowsphone.com/en-us/store/app/pok%C3%A9mon-iv-calculator/14c9ef93-ebf7-478c-9131-00d621d98716
Here's a list of features you can expect from this app:
Platform: Windows Mobile Phones (only)
1) Calculate IVs of ALL Pokémon till date (0 - 718), 3rd/4th/5th/6th Generations supported.
2) Easily navigate through the list of Pokémon arranged alphabetically with your finger or use the search bar to look for a specific Pokémon (a Pokémon is selected as soon as you start typing in its name!)
3) Base stats of Pokémon included, displayed instantly as soon as you select a Pokémon.
4) Types & Dex# of Pokemon displayed as soon as you select a Pokémon .
5) Calculate Hidden Power of any Pokémon, including the "Type" & "Power" of the Hidden Power move.
I will be updating it as soon as I get more data or if there are any changes to be made.
