If you're looking for new, innovative or improved apps, here are four apps that are considered as the great big idea for their respective niches.

Google Play Music

The improved Google Play Music allows you to store your music online, so storage space won't be a problem. You also have access to 20,000 songs for your collection, all for free, and you can even save them offline so you can playback when you're out of wi-fi reach.

More countries can now enjoy Google Play Music, including Australia, New Zealand, Ireland, Austria, Luxembourg, Portugal, and Belgium, reports The Next Web.

Burner

Burner took the niche for the clever idea of providing you with a temporary phone number, which, you have to admit, can come in pretty handy in certain situations.

When it was first launched, it was only available for the iOS, but now, Android users can take advantage of this neat little app.

According to TechCrunch, Burner is free to download, and you get one free Burner number. However, there's a reason why they're topping the charts as an iOS app. For $2, you get 3 credits or a Mini Burner, a number that allows you to remain anonymous for a week, 20 voice call minutes, or 60 SMS messages, depending on what you use your credits for.

So the next time you feel you need to hide your identity-whether it's a prank call to friends or a date that you just want to be very sure about, go for Burner.

Babblr

Tumblr has always been seen as a picture-sharing site, where your followers and anonymous users can also comment on your posts. For the younger ones, this may be a more passive way of interacting with people, which is why Tumblr needed something that would make its users have a more active way of connecting with each other.

Thus Babblr was born. It's currently in the beta version, where you can chat in groups, those you are following, and your followers, reports Digital Trends. The functions are easy to maneuver, and the Babblr team promises that there will be more offers when the full version comes out.

Babblr will launch in a few weeks, and its founders Brandon Sowers, Brett Williams, and Trevor Clark are hopeful that Babblr will make Tumblr a more cohesive and a sort of one-stop social networking for the younger generation, who are into instant one-on-one and group messaging.

The full version will be available on May 7, but will require a one-time fee of $0.99 for downloading.

Ribbon

Have you ever wanted to buy something online, and just after so many steps of clicking on the item, choosing the quantity and price, and adding your details, you suddenly have to do a myriad of steps when the browser jumps to the payment section, conducted by another site?

For the most part, this is what's tiresome with online purchases, but this is also where Ribbon plans to take up its niche.

According to All Things D, Ribbon co-founder wants to make it easier for online buyers to make the purchase by bringing the payments directly to where you're already making the purchase.

"We're trying to make selling across multiple platforms as easy as copying and pasting," said Rashwan to All Things D.

How it works is that the sellers will register their items for a link. This way, they can share the link to potential buyers, and if they are interested, they can click on the link from where they saw the item, make the purchase straight from there, and done.

In the long run, if you have a consistent buyer, Ribbon also makes it easier for that person by remembering the payment and shipping data so it will easily become a one-click shopping process.

However, when it was first launched in Twitter, Tech2 reports that Ribbon was already shut down. While there has been no official response as to why this was so, the in-stream app is currently not available for Twitter, but the app's founders are currently waiting for further progress.
