Found a new tool that helps calculate IV since Niantic disabled PokeAdvisor’s API access. In some ways its more awesome than PokeAdvisor in that it does not violate terms and conditions and that is a simple screen overlay. This one is not a 100% accurate nor does it provide hidden values but it gets you in the ball park in a fairly easy fashion.
This one is an Android App called IV Calculator for Pokemon GO. IV Calculator provides the tool as a screen overlay and as you can see below it is very close to the values provided by PokeAdvisor.
And before I can even finish writing this MrsRedBeard finds more
By now many of you may already know about evolving an Eevee into a specific evolution but do you know how to maximize that evolution? If you have not done this yet perfect we will go over the trick as well.
First you want to identify 3 Eevees that have the highest IVs preferably 85% or higher but the highest you have regardless. If you want to know how to check the IVs checkout the IV article and come back.
Second name the Eevees – Sparky, Pyro & Rainer. Note that these are the names of the trainers from the anime that originally held these. Also note this trick only works guaranteed once. These evolutions are listed below.
Sparky to get a Jolteon
Pyro to get a Flareon
Rainer to get a Vaporeon
Third now if you have enough candies evolve the 3 you renamed. If you used the trick above you should now have the 3 revolutions but with the maximum potential. Maximum potential unlike my Jolteon that I didn’t have this trick for before.
IV stands for Individual Value and this value stays constant even after evolution. The values for IV range from 0-15 and can be calculated from CP, HP and Dust with a calculation we’re not entirely sure of yet.
As previously stated the IV seems to determine the max CP you can obtain so the higher IV means the higher possible CP.
Still not clear take a look at this IV Calc for possible clarification.
Highest CP may not always be the best because high defensive points but low CP might be a good gym defender. So don’t go getting rid of everything with a low IV score just yet.
It was found by RedBeard that it made life easier if you renamed the pokemon according to their IV because IV is not displayed in Game. This also gives alternate sorting and makes decisions to transfer easier to determine. See pic. The CP is the % value below the pokemon.
