People often say that there's an app for everything – and Yo! could be the very proof of that statement. Its single function is to allow users to send 'Yo' in the form of a simple text message, wrapped in a context that can mean whatever they want it to mean. Yes, that's it. It does nothing else.
From a theoretical perspective, Yo!'s simplicity and single-purpose design make it a mobile app with a high degree of usability. Yet at the same time, it makes you wonder if usability is the only secret for its success.
Quick facts first: Yo! Is undoubtedly one of the hottest new apps on the market right now, with over a million downloads (and counting). It's reached the top 3 in the iOS App Store. Major news publications such as The New York Times have featured it, while it's even been discussed on a major US talk show. It's also inspired a couple of spoof apps, including one based on HBO's Game of Thrones. Unsurprisingly, the chosen replacement greeting is 'Hodor'.
But does Yo! have any real long-term potential, or is it just riding a viral wave that will end as abruptly as it started? You may think it's a little crazy, but we think it may have some traction.
How It Started
The app's creator Or Arbel cobbled Yo! together in a mere eight hours. It was launched on April Fool's Day earlier this year, which just about gives you the initial intention of the app. Released on Android only, there were no delusions of grandeur when it was first released.
The Main Mission
Many people think that the app's purported functionality is a gimmick – surely there's more to it? Well, the answer is one of those annoying 'yes and no' editions. The main mission of the app is to simplify the sending of a single message. You can literally send out a 'Yo' to a friend with just a single tap. The same message on Snapchat, Facebook, or WhatsApp would take you 11 taps. But of course, you're limited to 'Yo' and nothing else.
The Power of Context
So essentially, yes, the app only sends out a 'Yo'. However, it can mean different things. For example, recently added functionality allows bloggers to send out a message to subscribers that let them know new content has been released. And that's the kind of trend we expect to see in future.
The Snowball Effect
Despite being a basic app with code that's not exactly complex, it nevertheless started to take on a snowball effect. The viral interest has led to serious money being invested in the company (yes, it's now a company), to the tune of over $1 million USD. Ever since then, however, things have snowballed. Arbel, the creator, left a lucrative position of the stock-trading platform Stox to work on the app on a full-time basis.
The Technical Potential
The blogger functionality is just the beginning. We think the app is going to add further functionality, such as having the capability of adding links, notifications, photos, videos, and more. All driven through the phrase 'Yo'. The trick will be whether Yo! can maintain its simplicity while still adding functionality that makes the app useful.
Final Thoughts
Ultimately, we can't say for certain whether Yo! is just a flash in the pan project or something that will end up being a household name. However, we don't think it's just a summer fad. The amount of downloads, the social buzz, the media coverage, and financial investment means that the company is making a serious effort to stick around for the long haul.
