FlClashM is an open-source Android client for mihomo, based on FlClashX. It brings advanced censorship-circumvention tools into one app and keeps everyday use simple: import a YAML profile, choose the route, and connect. Profiles can use built-in ByeDPI, OlcRTC, StormDNS, and NaiveProxy nodes alongside standard mihomo proxies and rules. FlClashM also supports per-app split tunneling, QR/file/URL profile import, Android TV transfer, Quick Settings tiles and widgets, signed in-app updates, subscription expiry notifications, and automatic VPN startup after reboot.
