The Pokémon TV app has been available for iOS and Android devices since last year, allowing you to watch older Pokémon episodes from each season. You can see a few from Ash’s journey in Kanto, Sinnoh, Unova and all the rest. It’s gained over 2 million downloads since then but now it’ll probably get a few million more.
Amazon is getting in on the action by allowing users to download the app with the Kindle Fire device. It features weekly updates from the large catalog of Pokémon episodes. There are over 700 episodes that can be watched plus many more Pokémon videos. Download the app from the Amazon Appstore and get watching.
