A free app for Android, by Pascual Gorrita.

The PokéPedia app is the best source of information and strategy for any player of the Pokémon franchise. With this application, you will be able to know all the details of your favorite creatures, such as their type, level, health, attack, defense, special abilities, natures, and much more. 

In addition, you can check out their cry, which can help you determine their mood. Also, there is an option to create your own team, as well as a way to calculate the stats of your own team. This app can be downloaded for free on the Google Play Store.
