The Four Tabs
Once you enter a hub, you’ll see four tabs at the bottom of the screen:
PTT Tab (Push-to-Talk)
Your primary screen. This is where you:
- Talk using the large PTT button
- See who’s online in the members drawer
- Switch channels using the channel selector or channel dial
- Monitor additional channels
- Start calls via member action sheet (Whisper or Live-Sight)
Messages Tab
Your text communication hub:
- Channel messages — Each of the 10 channels has its own message thread
- Direct messages — Private 1-on-1 conversations with team members
- Image sharing — Send photos from camera or gallery
- Unread badges — Per-channel unread counts on each tab
Whisper Tab
Your hub’s member list for private voice calls:
- Member list — See all hub members sorted alphabetically or grouped by channel
- Start a Whisper call — Tap any online member to initiate a private, full-duplex voice call
- Presence status — See who is online, away, in a call, or offline
Live-Sight Tab
Your hub’s member list for 1-on-1 video calls:
- Member list — Same sortable list as the Whisper tab
- Start a Live-Sight call — Tap any online member to start a video call with audio
- Camera controls — Flip camera, mute audio, and toggle video during the call

Drawers
Drawers slide in from the side of the PTT screen:

- Transmitting — Currently speaking (with channel indicator)
- Online — Connected and available
- Away — App is backgrounded

Each member row shows quick-action icons for messaging, calling, and video.

Monitoring Drawer
Tap the headphones icon to manage channel monitoring:

The Channel Dial
The channel dial is a unique feature for quickly switching channels:
Long-Press the Channel Selector
Press and hold the channel selector button (shows current channel name) for 300ms.
Drag to Select
A circular dial appears with all 10 channels arranged in a circle. Drag up/down to rotate through channels.
Release to Confirm
Release your finger to switch to the highlighted channel. You’ll feel a haptic tap as you pass each channel.
For a simple tap (no long-press), the channel selector opens a grid modal showing all 10 channels. Tap any channel to switch instantly.
Overlays
Some features appear as overlays on top of the current screen:
- Active Call Overlay — Shows during Whisper calls (minimized bar or expanded card)
- Live-Sight Overlay — Full-screen video during Live-Sight calls with draggable PiP
- Tally Light Overlay — Recording indicator when connected to a video switcher
- Email Verification Banner — Reminder to verify your email (dismissible)
Status Row
Below the channel selector on the PTT screen, you’ll see a status row showing:
- Connection quality — Good (green), Fair (yellow), or Poor (red) based on ping latency
- Bluetooth status — Shows connected device name when BT PTT is active
- Hub name — The current hub you’re connected to
Navigation Tips
- Unread badge on the Messages tab shows total unread count across all channels
- Back gesture from the PTT screen prompts you to confirm before leaving the hub
- Waveform visualizer appears above the PTT button when someone is transmitting (or when you’re transmitting), showing the active speaker’s name
