Use this helpful tool to quickly advance in 'Pokémon GO'
Any experienced "Pokémon GO" player will tell you that the key to quickly leveling up your trainer is to evolve a bunch of Pokémon while using an item called a Lucky Egg. Evolving a Pokémon normally earns you 500 XP points, making it one of the most lucrative actions you can do in the game. Under the influence of a Lucky Egg, those points double to 1,000 XP per evolution. A website called PidgeyCalc helps you figure out exactly when to evolve a batch of Pokémon and the number of XP points you'll gain with a Lucky Egg. It'll even tell you when you should hold off on evolving and catch more creatures instead. For those looking to not waste a bunch of Pidgeys and Weedles, it's a must-use tool.
Pidgeys are one of the most common Pokémon in the game, and they're great to evolve because they only need 12 candies. On PidgeyCalc, I entered how many Pidgeys I had along with the number of candies I had to evolve with.
