This is as accurate as you can get as long as you use the screenshot feature to measure the Pokemon level. It's also very easy to use and figure out. Probably the best IV calculator you'll find!

This app is garbage and is a waste of time, don't use it. It's inaccurate and won't help you at all.

Easy to use tool that lets you see the IV's of a Pokemon without having to use an API or your password. Great tool if you are looking to understand The IV's of your Pokemon.

I have been calculating iv for a few weeks. It has been frustrating as the results were not reproducible depending on when or where I did the calc. I found the site suggested by Reddit, pokeassistant, to be inaccurate. I would get a bunch of different IVs depending on when I checked (powering up versus evolving). I can get different combinations every time I power up, which is just confusing if powering up makes a combination below the previous min. This app uses the level of the trainer and mon to give and estimated cp% (which other apps call the iv %). That would confuse me at first. It will say perfect iv score when the cp % (which matches iv % on other calculators) is less than 100. I just make a mental note of the cp%, and know that that mon is going to be one of the best. I also used the sliph road calculator, but I would get an inaccurate number unless I entered the level just right, and often the wrong level would match all the ranges. It is also a pain to use on a phone. With this app I just screen shot my pokemon, input the information from the picture, and I have a usable and accurate calculation within seconds. Perfection.

Was working until last update. In the update notes, he recommends another app for the time being. That other app is inaccurate. I'm level 26 and other app says I have level 28 Pokemon. They are actually level 27.5, making the numbers completely wrong. Please fix!

I used this after trying constantly to use the websites that do the same thing. This is much better! It can be difficult to eyeball the arc position for websites from your actual Pokemon accurately, and it is also obnoxious to have to switch between the app and site. It is also faster, as it took me only a couple hours to go through all the IVs of about 170 Pokemon (intense, I know). This app is more accurate for me, because it places a shadowed arc on top of your screenshot with tics marking Pokemon levels so you know you're entering the correct values. I also really enjoy the screenshot feature, where you tap the screenshot button and it automatically saves the IV calculations screen for you. (I dislike having to change hand position to take the shot myself, plus it's quicker, and easier for me since my case is a bit clunky.)
