There are a number of cool releases when it comes to Android apps free for download, and if you are looking for a particular app that you can show off to your friends, it's definitely this one. 

Made by well-known developer Ubisoft, 'Just Dance' is an interactive game that lets you dance with your friends and family or even with your officemates. 

So how does it work?

First, open the app and then connect it to an external screen, it may be a television set, your laptop, whatever. Then, visit www.justdancenow.com and connect your smartphone to the screen by following the instructions. 

Now, you can choose tracks you want to use for your dance party. Hold your smartphone in your right hand so the app can detect whether you're doing it right. 

After each track, there will be scores to see if you are really a dance expert.

What's good about this app is that it allows other people to join. In the game's Google Play page, it says that there are no limits to the participants so it will work best in parties and other get-togethers. 

The best thing about this app is it comes for free from the Google Play Store. There are also a good number of songs and tracks which you can use for free. 

However, just like every freemium app, there may be some purchases to get the latest tracks or the best-selling songs you can use for Just Dance. 

Do you love dancing but you can't find the time to go to the club and party? In this new app from Ubisoft, you don't have to.
