Yes. The game supports a lot of items and tools to help you find, catch, train and upgrade your Pokémon. We can find them in the store or in some Pokéballs. Some support items can be mentioned as:  Incense: Item “hearing drop”, help attract the Pokémon to your location in 30 minutes.  Lucky Egg: Double experience points gained in 30 minutes  Egg Incubator: This is an item that helps hatch the collected Pokémon eggs during play, but it requires you to walk a certain distance to hatch.  Lure Module: Also a “drop hearing” tool that helps Pokémon gather to PokéStop in 30 minutes, other players near that PokéStop can also enjoy your Lure Module. Items can be purchased with PokéCoins (a coin in the game), but to get PokéCoins, pay actual money to buy it in packages. So, even if it’s called a free game, pay if you want to be a “professional Pokémon catcher”.
