Are you tired to choose recipient from list which contains only one person?

YA is really simplest communication tool on Earth. (Simpler than "o"!)

There is no ID.
There is no recipients list.
Off course, there is no message.

You can pair 2 devices by simple 4 digit PIN code.
And tap YA icon on the home screen. That's it.

YA messenger's function is only one, Just send single text "YA" to paired device.

Wanna say 'good afternoon', just YA.
Wanna say 'baby,I miss you' - YA.
'Ive finished work,I will go back' - YA.
'what's up' - YA

The possibilities are infinite.

Your recipient is only one. Just say YA.
