Back in October we reported that AppCircus was coming to London. And last night, not only was The Next Web in attendance to see the developers pitch their products, we were on the panel of judges too.

Just to recap, AppCircus is a traveling showcase event that lets local developers demonstrate their apps, with the winners getting the chance to be nominated for the Mobile Premier Awards, held during the Mobile World Congress in Barcelona in early 2012.

Nine apps were showcased at the event, and without meaning to sound patronizing or cliched, each one was genuinely very good, and it was a difficult decision to reach. I often cringe when I hear others say that, but it was true on this occasion, and its testament to some of the really exciting things happening in tech.

Here’s what we saw.

The Winner: Echoecho

“Echoecho is the simplest answer to the world’s most-texted question: Where are you?”

Echoecho is a free app for iOS, Android, Symbian (yes, Symbian) and BlackBerry, with Windows Phone 7 coming soon. It strives to solve the problem of discovering where your friends are, without going through the painful texting/calling process that often begins with ‘where are you?’, followed by multiple attempts to explain which landmark you’re next to.

The app works anywhere in the world, and it taps into the contacts in your phone’s address book, meaning all you need to do to discover where someone is, is tap on their entry within the app, which sends a request to your friend who must then give permission to reveal their location on a map, alongside your location. You can also choose a venue nearby to meet at, whilst it has a built-in instant messaging feature too.

The Echoecho invitation can also be sent directly by text, with the Webecho feature allowing people to share their location without downloading the app, which is a very key component of this app.

Of course, this sounds a lot like what Google Latitude already offers, but by requesting location information, Echoecho effortlessly bypasses any privacy concerns. And because it’s not constantly broadcasting location data, it shouldn’t drain the battery either.

It apparently already has users in 165 countries, despite only being launched in September. Here’s the Echoecho promo video:

The runner-up: Siine Writer Pioneer Edition

“The first icon-based keyboard that combines standard world-class Qwerty features with icon-keys that can be personalized making your messages sound like you.”

This was an interesting one to say the least. Siine Writer is a London/Barcelona-based startup that has developed a keyboard for Android touchscreen devices, and it sells itself as the first icon-based keyboard that combines standard Qwerty features with icon-keys that can be personalized. The icon buttons can be tailored to your needs, so that long strings of text can be entered with a single click – and the icon images can also be personalized by a user, who can upload their own images.

The judges concluded that there was great potential for this app, in terms of optimizing smartphone keyboard accessibility. Here’ s the promo video:

Honorable mention: Runtastic Road Bike PRO Cycling Computer

RT Echoecho, the mobile app that lets you locate your friends, wins AppCircus in London

This iOS app got an honorable mention, because it seemed like a very well designed, beautifully constructed app. And the pitch was very good too.

The Next Web has a lot of time for health and fitness technology, and there is a myriad of apps out there already, but Runtastic seeks to differentiate itself as the “ultimate road cycling performance app, which transforms an iPhone into the best bike computer on the market.”

You can monitor your ride with sensors (available as separate hardware), and the app saves the data to each cycle session, such as weather, pace, altitude etc. And you can also see the sunrise and sunset time in the weather overlay. You can even get a summary of your session via a voice feedback feature, and you can involve your friends by letting them track a bike ride/race live online, giving you encouragement in real-time.

The Runtastic team has a series of health and fitness tracking apps, which have garnered somewhere in the region of 4m downloads, which are pretty impressive numbers and shows they’re doing something right.

Here’s the 6 other apps that were pitched at AppCircus…
