Yo 1.0.5 for iOS (iPhone screenshot 001)Yo 1.0.5 for iOS (iPhone screenshot 002)

There’s a new messaging app in town and it’s unlike anything you’ve ever tried. It’s lightweight and efficient, doesn’t require you to provide a screen name, won’t ask for your cell phone number nor will it pester you with ads – and boy is its Home screen icon unique.

It’s called Yo. (with the full-stop) and could easily be the simplest and most efficient communication tool in the world, with an insane twist on the mobile messaging concept…

Forget about smileys, auto-disappearing messages, the 140-character limit, video/audio messages, media transfers and other features commonly associated with modern messaging and micro-blogging platforms.

In Yo., all your feelings, moods, expressions and thoughts get compressed into a two-character message: “Yo”.

I kid you not, this is from iTunes release notes:

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.

They don’t call it “a single-tap zero character communication tool” for no reason.

App icon?


Yo 1.0.5 for iOS (app icon, small)

Developers said Apple at first rejected the app because its reviewers thought the icon was incomplete.

I’m not sure which is crazier: that the app – which conveniently launched on April Fools’ Day – has already seen two million messages sent just last month or that its developer has managed to secure a cool $1.2 million in funding.

Anyway, if you want to give Yo. a whirl, go ahead and grab it for free in the App Store.

The app is iPhone/iPod touch only and requires iOS 5.0 or later.

  • Rock Lee

    Yo. app I’m really happy for you and Imma let you finish, but the Messages app on the iPhone was the best app of all time!

  • Marcus

    I only use Messages & Facebook Messenger and I think it will stay that way for now.

    How is this different than a facebook poke?

  • Semek

    This is dumb. I really need to make some app looks like people will invest in any old garbage these days. There’s no reason why i shouldn’t be scamming these big bucks from someone.

    Investor(s): write a $1.2 million check… YO-LO!

    I actually like the look of the application, reminds me a little of the reminder application “Clear”. If they kept the look, allowed users to send media/text, and created a real icon it might take off. I know it’s a tall order, but I do enjoy the unique approach. Sadly this application is currently nothing more than a joke.

    It does require a screen name AND phone number…

    • T_Will

      It didn’t ask for my phone number, just a screen name.

      • EDiTOR9

        Did you give permission to access your contacts? That’s when it asked for mine. Regardless, Christian, should thoroughly check the app before posting a half assed review.

      • T_Will

        Ok yeah, when you invite friends, it requires permission to access your contact list in order to send the invite.

        The contact list permission doesn’t necessarily mean they are scraping your contact data and uploading it to a server, but I don’t know a way to verify whether they are doing this or not.

      • EDiTOR9

        I here ya. It didn’t bug me at all just that Christian’s article was inaccurate is all. I ended up deleting it either way :).

    Do we really need another messaging App?


    There are many more too …

    • justme

      competence is great for users, we benefit of it, but sometimes is very annoying seeing many of those weird apps trying to get your attention.

    • yes we need these messaging app keep coming because they kept evolving

      i hated whatsapp since 3 years ago and refused to had that lame looking shit installed on my phone and i can’t believe after all these years whatsapp still look just as lame …

      btw, i think Talk recently released by PATH had done a really nice job and people should give it a try, it had revolutionised the IM category
