App Navigation
The app uses a four-tab layout at the bottom of the screen:
Devices
Your main dashboard. Shows all connected devices as cards with real-time data graphs. Tap any device to open its full monitoring view with detailed graphs, spectrum analysis, and settings.
Scan
Discover and pair new LF Audio devices. The app scans for nearby Bluetooth devices and shows them in a list. Tap a device to begin pairing.
Generator
A standalone audio tone generator for system tuning and speaker testing. Works independently — no device connection required. Supports constant frequency and sweep modes with multiple waveform types.
Settings
App-wide preferences including temperature units, display precision, screen behavior, notification preferences, and links to help and support.
