An “app” (short for application) is a software program that you can install on your phone. Most mobile operating systems such as Android, iOS, Windows Mobile and Blackberry have dedicated app stores where customers can search and download applications. App prices vary but you can definitely find some great ones for free.  Installation of each app will take space on your memory card – you can check the size of the application before you start downloading.

Here are 5 free apps we think you should check out:

1. Shazam –  Ever hear a song and wish you knew the title? This app can identify songs within seconds. It will also help you buy the track, watch the video or view the lyrics.
