i woudl like one for all phones
No chance. Actually, Android being the most Linux of all the Phone OSes, has seen on just about most Smartphones (even ones that normally don't come with Android 2.1, or Android at all).. Ask TweetDeck team.
That brings up two issues, one who to include and leave.
I said I use a Pokedex app on my Android phone.. The only two things I use it for is to check movesets, and more often the Evolution method/level.
I usually look at the sites like Serebii, Veekun and Bulbaedia, when I'm looking to build my team, properly. I've also used MetalKid and Waiting for Seedot mainly for their tools unique to their sites.
I only use the said App when I'm playing where I can't get to my PC. Same goes for the Twitter apps I use. TweetDeck for Windows, and TweetDeck for Android.
Actually I lied about the App. The free version has also the Links to Serebii, Mariland and Bulbaedia..
Ok, Serebii needs Ads or Payment to keep this site going. While Android has Adverts in their apps, the developer wants that, and not to Serebii. Some stuff has trouble selling with prices on it.
I'm going to say not expecting to happen.
