Control OBS is the most complete OBS remote control app for iPhone. Created for IRL streamers first, but can be used by anyone! Whether you're a solo streamer, live event producer, or content creator, take full control of your OBS setup from anywhere in the world. --- SCENE CONTROL --- Switch scenes instantly with a single tap. Live scene previews let you see exactly what you're cutting to before you cut. Studio Mode is fully supported - preview and program views, scene transitions, and transition duration control all at your fingertips. --- AUDIO MIXING --- See every audio input in real time with live volume meters. Mute and unmute individual sources, or use Smart Mute All to silence everything in one tap and restore each source exactly as it was when you're ready. Filter inputs by scene so you only see what's relevant to your current setup. --- STREAM & RECORDING --- Start and stop your stream with a confirmation prompt so you never go live by accident. Monitor live bitrate, dropped frames, and data sent in real time. Recording controls include start, stop, and pause. Set recording to start automatically when your stream goes live, and stop when it ends - or override it per session with a single tap. --- ACTION DECK --- Build a fully customisable button deck for your most-used OBS actions. Fix broken media sources, toggle scene items, mute sources, switch scenes, start or stop your stream, save a replay clip, toggle Virtual Camera, and more. Assign custom colours, icons, and labels to make your deck your own. --- PERFORMANCE MONITORING --- A live stats dashboard shows CPU usage, memory, render lag, encoder lag, dropped frames, and stream bitrate with a quick graph. Know exactly how your system is performing without switching away from your broadcast. --- SOURCES & FILTERS --- Browse every source in your scenes, toggle visibility, and manage filters directly from your phone. Source renames in OBS are reflected in the app instantly. --- VIRTUAL CAM & REPLAY BUFFER --- Toggle Virtual Camera on and off and save replay clips to disk with a single tap - perfect for highlight capture mid-stream. --- CONNECTION OPTIONS --- Connect directly over your local network with automatic OBS discovery - just scan a QR code from OBS WebSocket settings or let the app find OBS for you. For remote access away from home, connect via a proxy URL from anywhere in the world. --- DESIGNED FOR STREAMERS --- Dark and light mode. Customisable tab order. Haptic feedback. Keep-screen-awake mode so your phone stays on during a broadcast. Session history to review past streams and recordings. Control OBS connects using the OBS WebSocket plugin, included with OBS Studio 28 and later. No additional software required.

Verdict

The call

The clearest difference is review sentiment: Control OBS at 100% against HDMI's 52%. Control OBS also leads on rating (5.0 vs 2.9) and iOS requirement (15.1 vs 17.0). HDMI's advantage is ratings volume (72 vs 2) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
