It's time to take a look at the vast world of smartphone applications once again, covering all the major platforms.

This time, we have a BlackBerry app that allows you to take photos and video simultaneously, an Xbox 360 classic on iPad and "Waze for people".

Unlock with WiFi

One of the more convenient single-use applications we've come across, Unlock with WiFi is certainly worth checking out.

As the name implies, when you're at a known WiFi hotspot, the phone simply needs a "slide-to-unlock" gesture. Move out of that zone though, and your handset will require a PIN code, making for a great security tool.

Unlock with WiFi is available from the Google Play store for roughly R20.

Bastion

One of the Xbox 360's greatest games has made its way to the Chrome browser and PC, and now it's coming to the iPad.

The action RPG boasts an accessible control scheme, fast-paced combat and absolutely beautiful HD art. So there's little wonder the original version claimed so many awards.

Bastion is available on the iPad 2 and third-generation iPad for $4.99.

Mikey Shorts

There's no shortage of platformers on smartphones, even spawning sub-genres, such as endless-running.

However, Mikey Shorts is a refreshing throwback to the platform title of yore, featuring simple controls and a charming style. Additionally, the game is made with speed-running in mind, allowing users to share their best times.

Mikey Shorts is available on iOS for the low price of $0.99.

Mecho Wars

Inspired by the Nintendo-exclusive Advance Wars series, Mecho Wars borrows more than its fair share from the critically acclaimed franchise.

Featuring land and air units, cartoony visuals and some casual strategy action, Mecho Wars brings accessible gameplay to iOS gamers.

A sequel to the game, called Mecho Wars: Desert Ashes, is in the pipeline, so get in on the action with the original, available for $0.99.

Swarmly

Described as "Waze for people" by TechCrunch, Swarmly swaps out highways and intersections for clubs and restaurants instead.

Swarmly shows where the most popular venues are, being represented with circles of different colours. The app is simple enough to use, but of course, being a new service, it still needs some more users to hit critical mass.

Swarmly is a free download for iOS so check it out when you have a moment.

Grooveshark

One of the more popular streaming services, Grooveshark also lets users upload their music library for everyone else's enjoyment.

The service has endured a few legal woes in the last few years, but it seems to have endured them just fine. Still, the app is not available on Apple's App Store, being on the Cydia store for jailbroken iPhones instead.

The app returned to the Google Play store over the weekend but has since been pulled again, so download it from the Grooveshark mobile website instead. Apps are also available for BlackBerry and Symbian handsets from the mobile site.

Dual Camera

We have another BlackBerry application this week in the form of Dual Camera, a neat video/photo program for RIM's devices.

The application lets users take photos and record video at the same time, much like HTC's One X and the Samsung Galaxy SIII.

The Dual Camera app is available free of charge from the BlackBerry App World, so you have nothing to lose.

McPixel

Gaining a cult audience already, McPixel has you solving a series of quickfire puzzles, involving a bomb about to detonate. The catch is that you only have 20 seconds to solve them.

McPixel is available on both Android and iOS in Lite and full flavours, with the latter costing $2.99.

It's hard to convey what McPixel is all about, so the guys at TouchArcade played through the game (note that this obviously has a few puzzle spoilers).
