NEEDS TO BE UPDATED. Niantic have removed the notification panel from the game screen which now means that this ago Is next to useless. There are a few errors in estimated evolution cp. Out of all the iv calcs i have tried this is the simplest and easiest to use while still playing the game, has next to no permissions and is easy to read and understand. It needs updating as soon as possible after new pokemon releases, if it's not updated soon after the next batch is released i will find another app to use. The few minor bugs need to be fixed as well. Happy to give 5 stars and pay $2 if it works properly and is updated in a timely manner.
I used to rely on this app on my old phone, but when I upgraded to a Galaxy s8, the arc overlay part of this app doesn't align properly on this phone (probably due to the s8's "infinity screen"). It's a shame because I really liked this app, but due to this issue, I'll have to resort to using Stardust, instead of the overlay, to calculate my IVs.
Very useful app and easy to use as overlay. Only thing missing for me is the ability to filter the results by what the appraiser says (need improvement, decent, strong or best) when it's giving IVs over two level brackets.
This is my favourite IV calculator. You can calculate the IVs of all your Gen1s and the first 80 released Gen2s including the baby Pokémon. The overlay works excellently, unlike some others that are really glitchy. I don't review apps often but I was looking forward to giving this 5 star review as soon as they added the 80 Gen2s to the app, which they did within 72 hours of Niantic releasing them. Great app. Thanks.
This app is one of the nicest to use IV calculators available. The downside is it just doesn't stay up to date whenever new updates change the meta (currently Feb 2017 they've been slow to add gen 2 but even worse have not updated attacks for gen 1, many of which now have new and better move sets then the ones shown). The IV is not always accurate either leading to a few inaccuracies. All this said its still good when up to date and working properly, and is totally safe to use as it doesn't interact directly with GO (which can result in a ban risk).
This was my go to iv calc, but since the new pokemon go update, the meter doesnt align. Nothing has been done to correct it. Sadly I am uninstalling.
Added Gen 2 move list
