PokeDream Dex 9+

Dex is very useful and does a solid job of cataloging Pokemon from each generation. Dex will also show you a new Pokemon each day, which is nice because I'm less familiar with Pokemon after Generation One, also known as Red and Blue.

The only complaint I have is that some of the information about levels that Generation One Pokemon learn their moves at is inaccurate. As I played the game I reached the allotted level and didn't learn the move. Looking at Smogon's PokeDex on my browser gave me different and more accurate information.

All said and done Dex is a handy mobile PokeDex for a casual or a devoted trainer.

This app was just what I was looking for. Just wish there was a way to turn the cries off without turning my phone volume off. Would rather just not have the cries all together. Really great app otherwise.
EDIT: With the ads in the app, I wish there was an option to pay to turn them off as an in app purchase.

The app itself is really solid. Comprehensive, well-organized, the sounds are a nice touch. Love that it has info across all generations (including RBY which is fantastic). It is everything I could possibly want in a pokédex app.
But, good lord, stop asking me to turn on Pokémon of the day. And those full page ads are killing me EVERY TIME I flip to a new pokédex page... This app is perfect but I'm using a different one now because this is so annoying.
Would gladly pay $2 or $3 for an ad-free version that would stop asking me questions and making me look at crap I don't care about.
