If you ever tried to get a party started by turning up the music on your smartphone, you ended up disappointed. Sure, when you're alone and listening on your headphones, the sound can be great.
But in a room with a lot of noise, and a lot of people, the music coming out of a smartphone can sound tinny and weak. The point is, you're not getting any party started with just one phone's sound system.
Which is where the AmpMe app should come in handy. Provided a bunch of people will all get off their phones, for an extended period of time, AmpMe can make those phones sound as loud as stereo speakers.
AmpMe syncs together multiple smartphones, including Android devices to iOS devices. If everyone has the AmpMe app, they log in. One person presses play, then that phone emits a high-frequency signal to the other smartphones. There is no delay, and all the phones start playing the same song at the same time.
The effect is that the individual smartphone speakers, combined, turn into a loud, thumping speaker. Now, that can get a party started.
Note: AmpMe currently works with SoundCloud, but its creator expects other music services to sign on soon.
