SMProxy is a client for connecting with your own configuration. One app across all your Apple devices: iPhone, iPad, Mac and Apple TV. Your settings and server lists carry over, and the interface is the same everywhere. The app provides no VPN servers, contains no built-in connection and sells nothing. To get started, add a configuration you already have: paste a link, scan a QR code or enter the details by hand. Modern protocols are supported: VLESS, Reality, WireGuard, AmneziaWG, Hysteria, TUIC v5, VMess, Trojan, Shadowsocks and Socks. Smart routing Not all traffic needs the tunnel. You can set exclusions by domain, IP and subnet (CIDR) — so your banking app or local network goes direct, for example. Routing rules from your configuration apply automatically, and the bundled geoip and geosite databases let them take effect instantly. DNS protection DNS queries are kept inside the tunnel so they cannot leak around it. You can also enable DNS-over-HTTPS and point it at any resolver you like. Server lists under control Automatic server-list refresh with an interval you choose, refresh on app launch, and a button to refresh everything at once. Server groups can be collapsed when the list gets long. Features • Import a configuration by link, QR code or manually • Pick a server manually or automatically, with latency testing • Exclusions by domain, IP and subnet • DNS leak protection and DNS-over-HTTPS • TLS fragmentation for difficult networks • Local SOCKS and HTTP proxy for other apps • Light and dark themes • Daily traffic statistics • Auto-connect on launch • Runs on iPhone, iPad, Mac and Apple TV Privacy The app keeps no logs of your activity and shares no data with third parties. Your configuration stays on your device only. Website: https://smproxy.io

Back In Service watches your connection and wakes you the moment it returns. Waiting out a dead zone, a tunnel, a basement, a flight, or an outage? Stop pulling your phone out every thirty seconds to check the bars. Arm the app, set it down, and go do something else. The moment your device is genuinely back online, Back In Service sounds off. REAL SERVICE, NOT JUST BARS A tower with no usable data isn't service. Back In Service confirms the connection actually carries data before it alerts you, so you don't get woken by a signal that can't load anything. CHOOSE WHAT COUNTS Alert on any connection, or only on cellular, or only on Wi-Fi. Waiting specifically to get off hotel Wi-Fi and back onto your carrier? Set it to cellular and ignore everything else. PICK YOUR ALERT A gentle ping or a full alarm, with six built-in tones. Time-sensitive alerts can break through Do Not Disturb and a Focus mode, so an overnight outage doesn't go unnoticed. TUNE BATTERY AGAINST SPEED Three reliability modes. Battery Saver checks in rarely. Balanced is the default. Maximum keeps the screen awake for the most exact result — best on a charger. KEEP WATCHING Leave the app armed after it fires to track a flaky connection that keeps dropping, or let it disarm itself after a single alert. PRIVATE BY DESIGN No account. No sign-up. No analytics. No data leaves your device, and there is nothing to collect. Your settings are stored on your phone and nowhere else.
