Megaphone! for Android

Quick overview

Megaphone, created by Thareja Inc., is a free, easy-to-use microphone utility that converts your smartphone into a live mic. It lets you send your voice to external speakers so you can make announcements, lead a small event, or amplify speech during presentations.

How to set it up

• Pair your phone with a speaker using Bluetooth, or plug in an AUX cable for a wired connection.
• Launch the app and speak into the device’s microphone; the app routes the sound to the connected speaker.
• Adjust volume and any in-app controls to suit the room and audience.

Ideal situations to use it

• Small-scale presentations and classroom talks
• Social gatherings and parties
• Public announcements in informal settings
• Any situation where a quick, portable mic is needed

Known limitations to be aware of

• Older or uncommon phone models may not be supported, reducing compatibility.
• Bluetooth connections can occasionally introduce latency or synchronization problems.
• Intermittent disconnections have been reported by some users when using wireless speakers.

Compatibility checklist

Before relying on the app for an event:

• Verify your device model is supported and has a functioning microphone.
• Test the Bluetooth or AUX connection ahead of time to confirm synchronization.
• Try the app with the exact speaker you’ll use for the event to rule out unexpected behavior.

Bottom line

Megaphone is a handy, no-cost solution when you need a portable microphone. It’s simple to operate and works well for casual announcements and events, but plan ahead and test your setup if you’ll be using Bluetooth speakers or older hardware.
