10 Crippling Issues That Could Kill Pokémon GO
4. PokéVision's Usefulness Needs To Be Addressed
If you're unfamiliar with PokéVision, it's a site that uses the app's API (the internal code that dictates how PoGo interprets the various positions of all Pokémon and their spawn rate) to show you where they are in real time.
Keep an eye on PokéVision, and you'll know precisely when and where to go to catch every last one of them. So far, this has created quite the division of players online. Many label it as cheating, whereas others claim that as the main series would show you the vague areas where a specific class of Pokémon could be located before you catch them, it's close enough to the 'right way' to play.
Regardless, having any unaffiliated website 'ruin' a huge portion of the game has to be addressed one way or another. Either Niantic need to change the way the game world is populated, or they need to factor this information in to what you can see while playing.
Perhaps you could purchase an item (with real money or Gym-rewarded coins) that would let you see precisely where any nearby Pokémon are - like the Itemfinder, but for Pokémon - for a limited time?
Maybe catching a large amount of any one 'family' of creatures would then show a heat map of sorts, as to where other, similar Pokémon may be?
Regardless, thousands of us are already using PokéVision to make up for the lack of decent tracking in-game, and that's a big problem.
