Clash Plus
Top PickIts biggest strength is a consistent interface across every platform: Windows, macOS, Android, and iOS all follow the same workflow for importing subscriptions, switching proxy modes, and testing node latency — so switching devices doesn't mean relearning the app. It runs on the mihomo core, with rule-based routing, TUN mode, and DNS configuration all built in. New users can get running with the default setup, and there's plenty of room to tune things once you're comfortable.
iOS distribution goes through the App Store, making it the fastest path to install on any platform; the official site clashplus.io links to downloads for every platform. If you're new to Clash or need to move between multiple devices, this is the default starting point.
