So far it seems to be pretty accurate I will say though it does get pretty annoying with all the login errors and the speed in which it goes off line even when actively using it

Works very well. Wish there was a paid/no ad version. Helped me winnow out the dead weight I'd caught and been carrying since Pokémon Go launched.

Do not download this app. This will flag your account on Pokémon GO. These developers also try to steal your information. All these reviews you see, fake!

Works great. Have to click several times from the main/manual version to enable the ability to log into your account and see your actual Pokémon Go IV values. Please made a paid version to get rid of the annoying ads that keep running in the background while using the app. EDIT: After using for several weeks I got a Shadowban (couldn't see rare Pokémon). Please be aware I'd you log into your Pokémon account with this app you will be Shadowbanned. Poke genie is the best iPhone alternative out there.
