Megaphone
Your phone as a microphone, out loud through a Bluetooth speaker.
InstallUsing it
- Pair your Bluetooth speaker in Settings › Bluetooth (or pick it from the speaker button in the app).
- Hold the big button and talk — or switch to Tap to stay on.
- Turn the speaker up, then fine-tune with Volume boost. Keep the phone away from the speaker to avoid howling.
