One Button Megaphone

★★★★★ Best Bluetooth speaker megaphone app. Only $1 to remove a small unobtrusive ad. Perfect for my needs. PS: Echo is normal if you're too close to the speaker, just saying. Works that way in a stage set too...

★★★★★ I'm very glad to have discovered this megaphone app! I already have an amplifier, but no mic. So now all I need to do is simply hook the phone up to my amp and turn on the megaphone. Also, I discovered that I can use it as a line in mic for my Mac and PC, again saving me from having to purchase and new mic. I do wish it would run in the background, as it could be useful when capturing audio from other apps. Great job!

★★★★★ works well, would give 5 star if i can use while screen in locked

★★★★★ Why does this app insist on recording the sound. The point of a megaphone is to amplify not record. I would download a voice recorder if I wanted to record voice. I looked for the recordings and cannot find them, so more disk space disappears into the ether as I cannot delete the recordings. Thank you for the update.

★★☆☆☆ Was trying to use it to amplify my voice for a gym class I'm teaching. There is a second delay so it's very irritating needless to say.

★★☆☆☆ Contradictory directions regarding having external speaker box checked (says checking not recommended) so proceeded as such and next prompt was to check external speaker and wouldnt execute until I did even though I was just told that wasn't recommended; thus not considerate of time. After proceeding with caution with very low volume the app launched and I could speak into the mic with my voice thru my external speaker but could barely hear me and could hear intense volume of feedback loudly. Tried to adjust volume for maybe half a minute before chalking this up to another useless app and uninstalling. Catch up with yourself U.S.A., you're not ahead.

★★☆☆☆ Too much echo. But I've had that experience with every megaphone app I've tried thus far. It would be nice to find one that was clear so if anyone knows if such a thing exists please let me know. It's important because I want to hook my little lavilier mic up close to my mask, that way I won't have to yell or sound muffled when I talk. It's just annoying with an echo. I'm deleting this app right after I submit this review. Thanks for trying, let me know when a better version is available
