Codemon was a free online barcode-based monster collecting video game developed by Platty Soft and released for Android mobile phones that are version 2.2 and up. It takes inspiration from both the Pokemon series and the Skannerz toys from the early 2000's. It can be downloaded directly through the Google Play store app.
It uses the built-in camera and scanner in Android smart phones to allow players to scan barcodes to collect Codemon and other useful items. Players can then take their Codemon to the Codiseum and battle them against fellow players.
Players can also interact with others through the Market, where one can sell or purchase Codemon and other items.
