Sadly PokeAdvisor is still down but in the mean time here are some new tools. This was going to be one tool but as updates roll in I ended up with 3.
IV Calculator for Pokemon GO
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
GoStats
GoStats is an app for android that appears to use your login credentials to pull stats from Niantic. The end of the video below talks about it.
PoGoBag
Ok so PoGoBag looks a lot like PokeAdvisor and appears to operate in the same fashion. I have a screenshot but I also got the following message so I’m not sure what their status is at the moment.
If you haven’t come across the Trainer Tips channel on YouTube yet be sure to do so. Each episode is packed with tidbits of knowledge.
