The simplest & most efficient communication tool in the world.

Yo is a single-tap zero character communication tool. 
Yo is everything and anything, it all depends on you, the recipient and the time of the Yo.

Wanna say "good morning"? just Yo.
Wanna say "Baby I'm thinking about you"? - Yo.
"I've finished my meeting, come by my office" - Yo.
"Are you up?" - Yo.
The possibilities are endless.

We don't want your email, Facebook, there is no search, no nothing. just Yo.

Open the app, tap Yo, that's it.

It's that simple. Yo.

Aside from communicating with your friends and family you can also get Yo's from what ever you like and interest you.

The Yo Index - see what Yo's you can subscribe to as provided by different websites and services. subscribe to what interest you and get notified on it. If you see a star next to the Yo, tap it to see the attachment.

Yo your location with double tap!

    Seems to work fine (521, dev prev). I think they need to guide people better as to what it is/does and how to get to using it. And give more of a vision of why you'd want to.

    App doesn't work. It displayed error messages when I tried to make a username that apparently meant nothing. Finally got my name setup, gave my username to friends. They said they've been sending me a bunch but I haven't received a single one. Wait until there's a patch that works. Don't get this app.
