+### Default iOS client: meow
+
+[meow][meow-ios] is the default Shadowsocks client for iOS. Core features for Shadowsocks:
+
+- Shadowsocks outbound protocol support, powered by the meow-rs engine (Trojan and VLESS outbounds are also available).
+- System-wide VPN via a NetworkExtension packet tunnel — no per-app configuration required.
+- UDP relay (QUIC/HTTP3 reliability depends on the outbound proxy and may fall back to TCP).
+- Rule-based routing with domain, IP, GeoIP, and GeoSITE rules, plus CN-IP TCP bypass for split routing.
+- DNS over HTTPS.
+- Clash-style YAML subscriptions with profile switching, per-app proxy group selection, and latency testing.
+- Live traffic throughput monitoring and per-day usage charts.
+- Runs fully on-device with no data collection. Requires iOS 17+; distributed via TestFlight.
