Good, but should add a few things,

I think that the app is great but it could use a few things like I think we should add friends so you can battle your friends and also I think you should add trading so then you can trade your Pokémon with your friends so if you have multiple of the Pokémon you can trade with somebody so that they could have another Pokémon so they dont have to go out and find it themselves and they could just trade up their friends
