The Three Tabs
Once you enter a hub, you’ll see three 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
Settings Tab
Your personal and hub configuration:
- Edit Profile — Change display name and avatar
- Audio Settings — Waveform style, walkie-talkie sounds, noise gate
- Bluetooth PTT — Enable/disable headset button control
- Listen Only Mode — Receive audio without the ability to transmit
- Account — Sign out, delete account
Drawers
Drawers slide in from the side of the PTT screen:
Members Drawer
Tap the people icon to see everyone in the hub. Members are grouped by status:
- Transmitting — Currently speaking (with channel indicator)
- Online — Connected and available
- Away — App is backgrounded
- In Call — On a Whisper or Live-Sight call
- Offline — Not connected (shows “last seen” time)
Each member row shows quick-action icons for messaging, calling, and video.
Hub Settings Drawer
Tap the gear icon for hub configuration (admin/owner only):
- Channel names
- Hub description
- Invite code management
Monitoring Drawer
Tap the headphones icon to manage channel monitoring:
- Toggle up to 5 additional channels to listen to simultaneously
- Monitored channels play audio alongside your active channel
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
