What does the IV calculator do?

Does this Eevee have good stats or not?!

This calculator simply attempts to calculate the IVs (what are IVs?) for your Pokémon based on the information available.

As multiple IVs can give the same CP and HP values for a Pokémon, sometimes the range given can be quite large.

For example, the Eevee pictured to the right, this could either be a great Pokémon with almost full IVs, or it could be a fairly useless 29% Eevee.

What does the "refine results" button do?

Fortunately, we can narrow down what the IVs are for a Pokémon by powering it up, and then re-checking the stats.

So you don't have to remember all of the previous potential IV values, the tool does this for you, and you can enter the new stats too, to narrow down the possibilities.

For example - this Psyduck has quite a few options here:

So we can power it up once, enter the new values in the table, and filter it down:

And in this case, we've been very lucky and narrowed it down to just one result straight away. Sometimes you'll need to power up the Pokémon several times until you get an exact value, or a narrow range.
