Pokémon attack type coverage
This mini-app lets you select types corresponding to the attacking moves you've taught (or plan to teach) to a Pokémon. It then tells you how effective those types are at tackling every known Pokémon. Note: you can now select more than four types, which is useful for testing coverage for two or more Pokémon.
For example, if your Pokémon has one Normal attack and one Fighting attack you might cover a few Pokémon, but you would have nothing that can hit Ghost types. Add a Dark move in there and you cover that and more besides.
