LeagueLeader allows you to easily view and manage your ESPN fantasy football league on your Windows 10 Mobile device (note that neither this app nor its creator is affiliated with ESPN). This app navigates various portions of the ESPN website as a proxy for you, so that you can have a streamlined mobile experience managing your team. However, as such, these methods are volatile and changes to the website may cause LeagueLeader to lose functionality periodically until an update is released.
