Some are much rarer than others but how can we tell?Guide Go lists all currently available Pokémon on the app. It explains the rarity of each Pokémon with a simple and descriptive system.In addition, the app shows the evolution cycles for each Pokémon and explains how to hatch a certain Pokémon from an egg.Everyone can catch a Pidgey, but can you catch a Charizard?PS:this app is note created by the inventor of the game
