Over the last couple of years, mobile devices have created a huge market for applications. Apple has a dedicated App Store, where customers can find an app for just about anything. "There's an app for that" has become a household phrase, but the reality is that there are more like several apps for "that". Navigating your way through all the apps available can be time-consuming. I've compiled a list of apps here that you don't want to pass up.

Bing

Bing is an incredibly useful app that allows users to search the internet quickly and easily, and was developed by Microsoft. It was dubbed the best general search app by PCMag.com in 2009, and continues to improve. Users can search based on voice commands, barcodes and even photos, making it easier than ever to find what their looking for. The interface is very straight-forward, while maintaining an appealing aesthetic. Microsoft recently included a social feature, allowing users to see which of their search results their friends liked.

Wikipedia

The Wikipedia app, developed by the Wikimedia Foundation, is practically what mobile apps were invented for. This free app provides a wealth of information right at the user's fingertips, no matter where they are. It's perfect for when you need to quickly settle an argument over some obscure historical event. Even better, it can help you educationally pass the time and fill your brain with fun and interesting facts while you wait for a bus or your laundry to finish.

Instapaper

One of the best aspects of mobile devices and apps is that they are available to entertain or educate us when we're in otherwise boring situations. In the past, we were fairly limited to books, magazines and knitting needles while we travelled on the train, waited for a ride or an appointment. Instapaer is an app designed just for these types of situations. This app, developed by Marco Arment, is available for $4.99 and allows customers to collect articles and blog posts they come across online, but don't have time to read in the moment. Users can access these articles and read them on their iPhone when they have some spare time.

Skype

Skype is one of the best free communication apps available. Basic Skype accounts are free and users can text, voice and video chat across Skype accounts. Skype also offers some very competitive prices for international calls. It is a great way to stay connected with friends and family for free, from anywhere.

Find My iPhone

Find My iPhone was developed by Apple and is available free for all Apple's mobile devices, including the iPhone, iPod touch, iPad and Macs. The app was designed to deal with the fact that these devices are very popular among thieves, due to their high demand. In the event your mobile device is lost or stolen, the owner can access the GPS location of his or her property from another iOS device. Apps like Find My iPhone have helped reunite a lot of stolen property with its owners.
