Pokemon have three stats, which aren't directly exposed on the UI: Stamina, Attack, and Defense. (CP is a weighted value derived from these stats that tries to give a straightforward way to compare two Pokemon to see which is better without exposing the stats directly to the player.) Each Pokemon, when it's generated, is assigned a random value from 0 to 15 for each of these stats. These values are called IVs and they're a bonus on top of the stats the Pokemon would have from its species and level.

Let's take Articuno as an example. It has a base Attack stat of 192. If it had 15 Attack IV (the appraiser would claim that its attack is the highest possible) then it would be treated as 207, but a 0 Attack IV would still be 192. To determine the Pokemon's actual stat, this base value is then multiplied by a fraction based on its level. At level 20 (that is, if your trainer level is 20 and the Articuno's power up bar is maxed out) that multiplier is approximately 0.6. So the 0 IV Articuno would have an actual Attack stat of 115, while the 15 IV one would have an actual Attack stat of 124. The 15 IV Articuno would therefore be dealing ~8% more damage with every attack than the 0 IV one. This isn't an overwhelming advantage, but it's not insignificant either.

However, because of the way the damage formula works and where the rounding takes place, that extra little bump could end up making a HUGE difference in actual damage output: If a fast attack would deal 1.95 damage, it would get rounded down to 1, but if it would deal 2.05 damage, it would get rounded down to 2. That tiny little bump is technically only a 5% increase before rounding, but AFTER rounding that tiny little bump means you're dealing TWICE AS MUCH damage with your fast attack. This is most significant for high-speed low-power fast attacks like Fury Cutter, and when you've only got 80 HP, dealing 2 HP per fast attack instead of 1 HP means you need 40 fewer attacks to win the flight.

On the flip side, consider a Pokemon like Wailord, which actually has surprisingly low defense because it relies on its HP for survivability. A level 20 0 IV Wailord has 204 HP and 52 Defense, while a level 20 45 IV Wailord has 213 HP and 61 Defense. This means that the tougher Wailord can survive 22% more damage than the weaker one -- that's like being able to just ignore one out of every 5-6 incoming hits!

I'm not getting an app to do IVs. Like I only do raids I can do alone and if someone is gonna take a gym, IVs will not make a difference.

So, for me, IVs do not matter lol

I'm not understanding how stats are determined in Go when they're not shown.

Once I'm done having to wrack up raid battles for this mission, I'll only bother with the pokemon I want.
I've only ever entered one raid that wasn't empty (the Alolan Raichu) and my strongest pokemon are terrible battlers. '-_-. I'm fortunate to even win a gym battle.

If you know what the appraisals mean by your gym leader then you don't need an IV checker...

For example I know that if my gym leader (Blanche - Mystic) says that a Pokemon has "It's a wonder!" stats then whatever stats she mentions after are top tier, if those also are "It's stats exceed my calculations" then they are 15 (which as Coda said is the highest possible IV number)

[RedRum]

Oh interesting. I've never had an appraisal done before.

[Coda]

"Top tier" for overall stats in this case is that the total of the three IVs is between 37 and 45. "Top tier" for a single stat is 15, second tier is 13-14. So with these bits of information you can make a fairly educated guess as to what your Pokemon's IVs are within a couple points.

An app will let you pinpoint exactly what they are by reverse-computing based on HP and CP, the stats you CAN see. That said, I don't actually care about it at THAT level of detail. I'll take the thing that I CAN see and just go with the best I can get my hands on, but I'm not going to go for perfect 45s on everything.

EDIT: That said, I have a perfect 45 Gulpin. I look forward to getting enough candy to evolve it and see how it does.

[RedRum]

Question: Can stats increase and thus appraisals change when you either evolve or power up a Pokemon?

[Coda]

IVs don't change for any reason after the Pokemon is generated, not by leveling up or by evolving. Even in the main series games where you have things like Super Training that increase a Pokemon's stats, you can't influence IVs.

[Yokuutsu]

IVs can change if they're traded, I have heard....but idk

[Quiet Man Cometh]

This is all too much for me at the moment, but I suppose it wouldn't hurt to actually lean.

Tried to get an espeon recently and failed. Walked and got my two candies, but apparently the pokemon needs to be your active buddy when you evolve it and I swapped out just before evolving. I have enough to evolve again so I'll give it another shot. At least I did get an improved flareon.

I always find myself having a bit of debate when it comes to which buddy to walk with. I pretty much need to walk for my fire pokemon candy as they're so rare for me. I'm walking with my cindaquill to get what I need to evolve him one stage. But, I also want to start that eevee, and I've got it in my head now that I want to take Mighty for a walk to get him to 100km. He's at 80 right now. I could use a better arcanine than Howitzer but he and Mighty are what I've got.

I'm starting to get silly with names. I finally evolved a golem and called it "Amadea" (a girl, or it would be "Amadeus"). My two snow block sandshrews from Kentucky are now Igshrew and Sandloo. I've mostly laid off the puns so far.

2 raids into my 10 raid goal. I think I mangled 1 raid catch and that was a quilava. Otherwise, I've caught my magikarp, crocanaw, and ...something I can't remember. Most of the time I simply can't beat higher powered raids (tried for a porygon with no success) so I just join and ditch for my point.

I have two 'perfect' pokemon now, my jumpluff and now my slowbro. (Luff and Bro. How original, I know.) Neither are very high in the cp end though, but I find I stick most of the time with my main crew anyway. I've taken to annotating names with little characters that designate certain stats because I got tired of appraising all the time to be sure what something was.

Well, that's shitty.

You can control Eeveelutions via nicknaming them after their respective trainers in the anime, the Eevee brothers of Kanto and the Eevee sisters of Johto.
ex. Pyro = Flareon
Rainer = Vaporeon.

Sakura will result in Espeon.
I've done this successfully with Espeon and Umbreon. Though my Espeon's appraisal was poor, looks like I need to evolve another but female Eevee are so scarce---have been for me at least and I prefer Espeon female.

This is true, but that's because trading effectively generates a new Pokemon on the receiver's end instead of actually transferring the Pokemon. However, there are some constraints applied to the newly-generated Pokemon: The moveset is forced to be the same, and the newly-generated IVs have a minimum value based on your friendship level with your trade partner. (This means that trading a Pokemon with crappy IVs to someone you're best friends with is GUARANTEED to result in a much better outcome.)

Another interesting tidbit I just picked up is that another feature is enabled when you trade with a friend: The Pokemon has a chance to be "Lucky" which halves its powerup costs!

Quite the contrary, it means that wild Pokemon have variability and individuality instead of every Pokemon growing up exactly the same. IVs are like genetics, and in fact in games with breeding the parents' IVs have some influence on the offspring's, but the child will always have some unique traits instead of copying the parents directly.

I mean, yes, it's inconvenient that some Pokemon will always be a little bit weaker than others no matter how well you train them. But in terms of game design it's a very good decision.

This is basically what I meant, that getting a strong Pokemon with a good move set means capturing the species multiple times rather than training one.
Kinda frustrating.

Frustrating, sure, but also an explicit part of the game design, meant to reward players who put more effort into the game.

Also that's what TMs are for. Easier to change the moves of a Pokemon with good IVs.

Yeah I wish TMs weren't so ridiculously rare.

[RedRum]

I'm stoked. I just beat a raid at my park, a whalmer so nothing special (and it wasn't even stronger than the one I already had) but I now qualify if Mewtwo ever showed up there because my findings claim EX raids mos often appear at park gyms.

It's been a while since I've dog walked that route but it's a good route because I get 6 stops including two gyms and it's so much nicer just going with the friendly one of my two dogs.

UPDATE:
This is a semi-lucky day.
The good news: I got two raids into today, just 3 more until I've got that task out of the way.
Bad News: Second one was an Alolan Marawak again and again I could barely dent the damn thing. I'll never be able to beat one alone but no one else is ever around when raids show up around here!
