The Best POKEMON GO IV Calculator Is Not A Website, But An App

This is the first in a series of pieces I've been putting together, as an adult player of Pokemon Go. I've dug around, figured out how to play for free, how to create ass-kicking pocket monsters and almost have fun with it, without needing to obsess like we all did in that first year when we were making Niantic a million bucks a day.  (Yea, think about that when you ponder why the app never really improved as vastly as it did, sooner than it has.)

One of my tricks to playing Pokemon Go and keeping my "rolodex" of monsters from filling up is by tossing everything I catch except for the best of the best, meaning those with the top 20% IV scores. Face it, if you have a pocket monster (Pmon) with huge CP, but crap fighting skills, you won't last long.

Case in point, since I've focus on keeping only the best that I find, I can pretty much defeat a full gym with one Pmon if folks have stacked the gym with anything in their bag.  It's not so easy if you come up against a gym stocked by smart folks!

But to determine my Pmon stats, up until recently I've been using GameInfo's Pokemon Go IV Calculator at

What I would do is catch Pmons, then later at home or during some quiet time, go back and check my recent catches the game's Appraisal routine. I would only keep the Pmon that my appraiser would say "simply amazes..." her. For the other teams, the phrase would be "a wonder...," and "it can really battle..."

But every time I kick in the appraisal routine, I would have to cycle through all the observations my trainer had to offer and that took more time than I would like. When I'm in the field or picking through my recent catches, I just want to review and toss.

Hence, my new favorite Pokemon Go IV Calculator phone app, CALCY IV!

What an amazing app.

First, the general belief is that it does not violate Niantic's TOS agreement because it only takes screenshots and does the math that you could potentially do in your head, visually. It does not attempt to circumvent the programming, like some of the past monster map apps/sites.

You start Calcy IV first then from within that app, you can start the game. Calcy puts a button on the screen. So you pick a Pmon you want to review and then tap the Calcy button. It will read your screen and instantly tell you the IV Rating range. Boom, you're done.

Every now and then though, Calcy IV will say you have a Pmon with a wide range potential, and then you need to run your Appraisal routine to fill out a subsequent set of information options, and then it narrows it right down.

It makes appraisal routines much faster than using a third-party website or shuffling through the appraisal statements, when all you need is that very first IV impression. So far, it has not been a big hindrance to my game when I do run it. At all... once you get that floating button where you want it.

The app saves a huge amount of time, and as we all know from Pokemon Go, time is battery!



What Are Pokemon Go IV Numbers?

IV stands for Individual Values. Your Pokemon GO pocket monsters (Pmons) have Attack, Defense and Stamina IV ranks that range from 0 (sucks) to 15 (Best).  The game takes your three values and stacks them up to come up with a combined percentage score based off your IVs and CP (Combat Power).

IV numbers are connected to CP scores, because a CP score is comprised of Attack(ATK), Defense(STA) and Stamina(DEF) numbers too.

A lot of players I know tend to value the CP score more, but to be honest, if I have a Pmon with lower CP scores and an IV score of 100%, the other guy is going down. At least, that's been my experience so far when I've been taking down fully stocked gyms or easily taking down Gym Bosses during raids, by myself, with one or maybe two Pmons, at most. (Admittedly, I'm careful what Boss I tackle, but still.)

The downside is that you could get a great IV score but the Pmon has a bad moveset. Or so they say, but I am not too worried about that and it does not seem to impede my game.  OK, those STUPID LuvDisk things are useless, no matter what you think and I have way too many of their candy!


So to wrap it up, I never retain Pokemon Go pocket monsters that don't rank in the top 20% of IV rankings, which will guarantee that I have a real good collection of Pmons. Then I walk, spin, catch and release, collecting the stardust and eggs to further my game, because the bottom line is that I'll catch them all, as long as I'm getting stardust to help grow my favored power Pmons. Right?
