Learn more about the Yo. app in the video above.
Available for Android or iPhone, the Yo. app simply accesses your contacts, allows you to pick a person to send a “Yo.” greeting to, and then sends that person a push notification. There’s no typing involved, and the app is not capable of sending any other greetings. For now, the app is US-only.

According to TechCrunch, Yo. was hacked by college students. Yo has confirmed the hack. TechCrunch writes:
“A Georgia Tech student, together with two of his roommates, claims to have hacked Yo…The student emailed TechCrunch detailing what he alleges is the results of the hack: ‘We can get any Yo user’s phone number (I actually texted the founder, and he called me back). We can spoof Yo’s from any users, and we can spam any user with as many Yo. We could also send any Yo user a push notification with any text we want (though we decided not to do that).’
Meanwhile, a Vine video has emerged from Vine user Hako, of the Yo sounding out a snap of Rick Astley’s ‘Never Gonna Give You Up’ instead of it’s normal ‘Yo!’ sound.”
Quartz adds that at least one hacker was also able to make Yo. send out a message other than, well, “Yo.”
