Pay to have someone hand you free information – Pro Dex for Pokedex Pokemon GO - Best Guide Review

This app is nice if you're lazy and don't want to take a few minutes to read a plethora of online resources. Premium features (basically everything you'd download an app for) cost money. Still, if you haven't been reading up and don't plan to or want to wade through forums for this information, it can be good. I didn't try the IV calculator since it's a paid feature but I have a spreadsheet that works well. Nice to have that in app form, albeit a paid for feature.
