A streaming studio at sunset: next to a host holding a guitar, a tablet and a phone on the desk show MobileDeck OBS keys and a music screen, and the monitor shows the OBS stream

Premium OBS Studio control

Switch scenes, record, stream and mute the microphone with keys on your phone and tablet. The current scene, the recording time and whether you are muted show right on the keys, so you never need to look at the OBS window.

The OBS page on a tablet — the recording time on the record key, a mute mark on the Mic key, and a green border on the Talk key, the current scene
  1. 1Record — a red border and the elapsed time while recording
  2. 2Stream — a long press starts or stops it, so it never goes live by accident
  3. 3Microphone — ✕ when muted
  4. 4Scenes — the current scene has a green border

A whole OBS page in one go

Press «OBS page» on the ribbon of the PC settings window and you get a page filled with your OBS scenes and the controls you use most. No need to make the keys one by one.

The OBS group on the settings window ribbon — OBS page, OBS hotkeys, OBS keys
The OBS page on a phone in portrait — four scenes in the left column, and record, stream, microphone, desktop audio, virtual camera, replay and studio mode in the middle column
Phone in portrait — the tab shows O
The OBS page on a phone in landscape — scenes on the top row, controls on the middle row
Turn it sideways: scenes on the top row, controls in the middle
  • Scenes in OBS order — if you add scenes in OBS, press «OBS page» again on that page. Only the new scenes are added to the empty keys.
  • Microphone and desktop audio — finds the microphone and desktop audio set up in OBS and adds mute keys for them.
  • Phone and tablet separately — the tablet's 10-key rows also fit pause recording and screenshot.
  • Once made, they are ordinary keys: move them, rename them or delete them.

What a key can do

Select a key, press «OBS keys» on the ribbon, then choose what it does in the right-hand panel. Scene, source and input names come straight from OBS as a list.

Scenes · Sources

Switch scene · show or hide a source · turn a filter on or off · change the transition · toggle studio mode

Recording · Streaming

Start or stop recording · pause recording · start or stop streaming (long press) · save replay · virtual camera · screenshot

Audio

Mute · volume up · volume down — the key shows the current level in dB.

Media

Play or pause a media source · restart it from the beginning

Profiles · Scene collections

Switch between the profiles and scene collections you keep apart, such as one for streaming and one for recording, with a single key.

OBS hotkeys

The hotkeys you have set in OBS, as keys. More below.

Bring in the hotkeys you set in OBS

If you have assigned keys under «Hotkeys» in the OBS settings, open the list with «OBS hotkeys» on the ribbon and tick the ones you want. They go into the empty keys in order.

The OBS hotkeys window — Start Recording Ctrl+F9, Save Replay Num +, Add Chapter Marker F8, Mic/Aux Mute F1, Captions show F2, To scene Blackout F12
Only hotkeys that have a key assigned are listed, with that key
  • Nothing is typed on the keyboard — press the key on your phone and OBS runs that hotkey's action directly.
  • Source and scene hotkeys too — hotkeys tied to a particular source or scene, such as «Captions show» or «To scene Blackout», come in as they are (OBS 30.1 or later).
  • Names as OBS has them — each key is named the way OBS names the hotkey, and you can rename it later.
  • Hotkeys that are only on while held down (push-to-talk) do not suit a phone key, so they are left out of the list.

OBS, right on the keys

Change something in OBS itself and the phone keys follow at once. One look at the keys tells you what is on.

REC · LIVE

While recording or streaming, a red border appears and the time runs, such as «REC 12:34» or «LIVE 1:02:10».

Current scene

The scene on air has a green border. The current transition, profile and scene collection are green too.

Mute ✕

A muted input's key shows ✕. Volume up and down keys show the current level in dB.

Pause ❚❚ · Play ▶

❚❚ while recording is paused, ▶ while a media source is playing.

ON

ON for the virtual camera, the replay buffer, studio mode, and sources and filters that are switched on.

When OBS is closed

The OBS keys dim and show «OBS». Start OBS again and they reconnect by themselves.
