Windows: When it comes to voice chats on the web, Skype is definitely the way to go. This awesome app - chosen by three Softonic editors as top of the decade - keeps on improving with every new version. The latest one, Skype 4.2 Beta, features call quality indicator, Google Chrome extension, enhanced support for the Windows 7 taskbar and the ability to transfer calls.

iPhone: If you're growing tired of the default Clock feature on your iPhone and want a new way of waking up then check out Alarm Clock Free. This handy app turns your iPod into a stylish digital clock and alarm. The neon green-on-black clock skin bears a striking resemblance to Night Stand, but this is no bad thing, as it looks good and is easy to see from a distance.

Mac: There are few Mac applications that can compete with VLC Player when it comes to playing video but MPlayerOSX is a very decent attempt to do so. MPlayerOSX impresses by playing virtually any video file type. These include MPEG/VOB, AVI, Ogg/OGM, WMA/WMV, QT/MOV/MP4, RealMedia, Matroska, and many many more. It may be a little rough around the edges in places compared to VLC Player but it's definitely worth a try.
