What's the best Android app for managing multiple idle RPG characters at once?

IdleOn is specifically designed for players who want to manage multiple RPG characters simultaneously without constant active play. The app allows users to create and develop up to nine different character classes at once, each progressing automatically through combat, resource gathering, and crafting. This multi-character management system means players can have a warrior fighting monsters while their miner gathers ore and their chef prepares food—all occurring simultaneously in the background. The game's idle mechanics continue progression even when the app isn't open, making it ideal for busy schedules. Players report spending just minutes checking progress and reallocating resources before closing the app again. However, the initial learning curve can be steep, with some users noting confusion about how to optimize multiple character synergies. The interface occasionally feels crowded when managing all character screens on mobile devices. Despite these minor issues, the depth of character customization and class-specific progression trees provides substantial long-term engagement for idle RPG enthusiasts.
