As a part of Alpha 5.6 of the PokeDex, the mostly-complete versions of the IV and EV calculators have been completed. There are still some rough edges, notably all stats are approximate (in time I'll make it so the entire range of possibilities is printed), but they both work well. You can see them at the below links:

IV Calculator
EV Calculator

The final Alpha 6 will also feature a damage calculator (albeit rudimentary at first) and a PokeBall capture calculator.

Remember, comments and suggestions are always appreciated.

I love you.

I just have one suggestion to make the pages look better: try to add some photo/icon/etc of the Pokémon we choose in the calculators so that they aren't text only.
Otherwise, they both work perfectly well for me.
Good job, FreezeWarp.
