Hi guys,
I recently written up an EV Trainer written in PHP (for the Web), but so far the only feedback I've gotten has been from my little sister who's tried using it with her game.
Here's the link if anyone's interested in trialing it...

Just click on "Demo Version" and it will take you to the EV Trainer App.
Basically its meant to take away all the thinking involved with EV Training, ie you don't have to calculate how many points you get from a battle, etc.
One thing my sister pointed out to me however, is if you add one too many points (and you haven't hit "apply" recently) its a bit tricky to take back those points. I'm going to add a fix for that in the next version however I would like a bit more feedback first.
Another idea I had was to include a search filter for selecting your opponent so like you could specify by name or what stats they give points for in case you don't know already. But again it's more something I'll probably include in a future version after I get a bit of feedback...
