What's the best iOS app for managing my PC game library and buying games when I'm not at my computer?

Steam Mobile is Valve's official companion app for its PC gaming platform, designed to extend core Steam functionality to iOS devices. For managing a game library remotely, the app allows users to browse their entire collection, install or uninstall games on their linked PC, and view detailed community content for each title. Its most practical use case involves monitoring and participating in Steam's frequent sales while away from a desktop. Users can receive push notifications for wishlisted items that go on sale and complete purchases securely through the mobile storefront. The app also integrates Steam Guard mobile authentication, adding a necessary layer of account security. Reviews indicate the interface is generally reliable for browsing deals and making impulse purchases, which is helpful when a limited-time discount is about to expire. However, some users note that navigating the full store catalog on a smaller screen can feel cramped compared to the desktop experience. The app does not support streaming or playing games directly on the iOS device; it is strictly a management and storefront tool. For anyone who wants to keep up with Steam sales, manage downloads, or use two-factor authentication without being tethered to their gaming rig, this app serves its purpose effectively, albeit with a mobile-optimized interface that prioritizes utility over expansive browsing.
