After Google searching for a means in which to check the IVs of my Pokemon, I discovered an Ipod app.
You can download it here. (https://itunes.apple.com/gb/app/iv-checker-data-for-pokemon/id741401904?mt=8)
The app is designed for use with OR/AS but I suppose it could work for X/Y too.
It can even tell you what Hidden Power type your Pokemon has.
There are a few other little features the app has which I haven't checked out yet. I recommend downloading it and giving it a try.
I downloaded it, but it's far inferior to MetalKid's IV Calculator (http://www.metalkid.info/Pokemon/Calculators/IV.aspx), which also works in the iOS Safari browser.
The app does not take into account the data from the IV Judge, or the Hidden Power checker woman in Fortree (ORAS) / Anistar (XY). Also it doesn't combine the data from multiple levels like you can get by entering multiple rows in MetalKid's calc.
Its Pokédex is quite good but doesn't include the new ORAS move tutors. I have to add that much of the text in the app is badly translated from Japanese, though still understandable.
