WAONサービスアプリ is an Android app developed by AEON that allows users to make the most out of WAON, a convenient and cost-effective electronic money. With this app, users can receive campaign information, search for stores where WAON can be used, and check their WAON balance, point count, and usage history. The app also features Happy WAON, the mascot character, who welcomes users on the home screen and takes them on seasonal walks to different locations.
