Most mobile devices are sold with several programs bundled as pre-installed applications, such as an internet browser, email client, calendar, mapping app, and a program for purchasing music, other media, or even more programs. Some pre-installed apps can be removed by an ordinary uninstall process, thus leaving more storage area for desirable ones. Where the software does not allow this, some devices can be frozen to get rid of the undesired apps.

Apps which aren't preinstalled are often available through distribution platforms called app stores. They began appearing in 2008 and are typically operated by the owner of the mobile operating system, such as the Apple App Store, Google Play, Windows Phone Store, and BlackBerry App World. But, there are separate app stores, for example Cydia, GetJar and F-Droid.

Premium Android Apps

Some apps are free, while others have to be bought. Usually, they are downloaded from the stage to a target device, but sometimes they may be downloaded to laptops or desktop computers. For programs using a price, normally a percent, 20-30%, goes to the supply provider (such as iTunes), and the rest goes to the producer of the app. The same app can therefore cost a different price depending on the cell platform.

Programs may also be installed manually, such as by running an Android program package on Android devices.

Mobile apps were originally offered for overall productivity and data retrieval, such as email, calendar, contacts, stock market and weather details. But, public demand and the availability of developer tools drove fast expansion into other categories, like those handled by desktop application software bundles.

As with other applications, the explosion in number and wide range of programs made discovery a struggle, which in turn led to the introduction of a wide range of recommendation, review, and curation sources, including sites, magazines, and committed online app-discovery services. In 2014 government regulatory agencies started trying to control and curate programs, especially medical programs. Some businesses provide apps as an alternative procedure to provide content with certain advantages over an official website.

Usage of mobile apps has become increasingly widespread across cell phone users. A May 2012 comScore study noted that during the prior quarter, more mobile subscribers used programs than browsed the web in their devices: 51.1percent. 49.8% respectively. Researchers found that utilization of mobile apps strongly correlates with consumer context and depends on user's location and time of the day. Mobile programs are playing an ever-increasing part within healthcare and when designed and incorporated correctly can yield many advantages.

Paid Android Apps For Free

Market research firm Gartner predicted that 102 billion programs would be downloaded in 2013 (91% of these free), that might generate $26 billion from the US, up 44.4% on 2012's US$18 billion. From Q2 2015, Apple stores and the Google Play generated $5 billion. An analyst report estimates that the program market generates earnings of more than $10 billion per year inside the European Union, while over 529,000 jobs are made in 28 EU countries due to the rise of the app marketplace.
