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).
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.
Awesome handy tool to check on what to keep and what to transfer. ALSO There is a typo when too many possibilities are shown like doing a 10cp with 10 hp. Too* not "to" might wanna fix that.
Brilliant. Updated with Gen 2 Pokémon very quickly, nice work devs! Uses an overlay with no account details required so safe to use. Great stuff.
Used to work, but I just upgraded to a Galaxy S8+ and the meter stick no longer fits the screen. The IV calculations, when you can find a spot where it works, does not match up with the description of the pokemon given to you by your team leader.
Added Gen 2 move list
