Turn your iPhone into a megaphone
Need to be heard across a room, a classroom or a crowd? ShareMic works as a megaphone app: speak into your iPhone and your voice is amplified in real time through any Bluetooth or AirPlay speaker you already have nearby.
★★★★★Rated 4.2 ★ on the App StoreAny speaker becomes your PA system
Pair with a portable Bluetooth speaker for a tour or a market stall, or send your voice to a venue's AirPlay sound system for announcements. The bigger the speaker, the louder you carry — no dedicated megaphone to charge or store.
Clear voice, not distorted noise
Megaphones are famous for harsh, muddy sound. ShareMic's noise gate and feedback suppression keep your announcements crisp and intelligible, so instructions and directions actually get understood.
Made for teachers, guides and organizers
Project your voice in a classroom without straining it, lead a walking tour, run a small event, or make announcements at a gathering — all from the phone already in your pocket.

Frequently asked questions
Can I use my iPhone as a megaphone?⌄
Yes. ShareMic amplifies your voice live through any connected Bluetooth or AirPlay speaker, so your iPhone plus a speaker works as a wireless megaphone or PA system.
How loud can it get?⌄
Loudness depends on the speaker you connect. A larger or more powerful Bluetooth/AirPlay speaker will project your voice further than your phone's built-in speaker ever could.
Is the voice clear enough for announcements?⌄
Yes. A built-in noise gate and feedback suppression keep your voice clear and intelligible, which matters most for announcements and instructions.
