Aw, yeah! I got this app a few days ago and my first thoughts were: OMGTHISISTHEBESTPOKEDEXAPPEVER! Shame it doesn't have B2W2 and XY versions.
I fully support the development of this app. Although I have never worked on an Android app mod, I will try to help out. So, yeah, if you have a dev team, I'd like to join it.
Good Luck,
Wild Jr.
