Since the start of the COVID-19 pandemic and the rise in use of payment apps, there has been a notable increase in reported scams.[31] In one instance, a man was scammed out of $24,000 by customer support impersonation.[32] In another instance, a scammer used the public video of a female Waffle House worker holding a baby in a kitchen to fabricate an emotional story. The scammer used social media to share their Cash App information in the hope of receiving donations.[33]
Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Many apps require Internet access. Apps are generally downloaded from app stores, which are a type of digital distribution platforms.
Apps are broadly classified into three types: native apps, hybrid and web apps. Native applications are designed specifically for a mobile operating system, typically iOS or Android. Web apps are written in HTML5 or CSS and typically run through a browser. Hybrid apps are built using web technologies such as JavaScript, CSS, and HTML5 and function like web apps disguised in a native container.[2]
Most mobile devices are sold with several apps bundled as pre-installed software, such as a web browser, email client, calendar, mapping program, and an app for buying music, other media, or more apps. Some pre-installed apps can be removed by an ordinary uninstall process, thus leaving more storage space for desired ones. Where the software does not allow this, some devices can be rooted to eliminate the undesired apps.
Some apps are freeware, while others have a price, which can be upfront or a subscription. Some apps also include microtransactions and/or advertising. In any case, the revenue is usually split between the application's creator and the app store.[3] The same app can, therefore, cost a different price depending on the mobile platform.
Mobile apps were originally offered for general productivity and information retrieval, including email, calendar, contacts, the stock market and weather information. However, public demand and the availability of developer tools drove rapid expansion into other categories, such as those handled by desktop application software packages. As with other software, the explosion in number and variety of apps made discovery a challenge, which in turn led to the creation of a wide range of review, recommendation, and curation sources, including blogs, magazines, and dedicated online app-discovery services. In 2014 government regulatory agencies began trying to regulate and curate apps, particularly medical apps.[4] Some companies offer apps as an alternative method to deliver content with certain advantages over an official website.
With a growing number of mobile applications available at app stores and the improved capabilities of smartphones, people are downloading more applications to their devices.[5] Usage of mobile apps has become increasingly prevalent across mobile phone users.[6] A May 2012 comScore study reported that during the previous quarter, more mobile subscribers used apps than browsed the web on their devices: 51.1% vs. 49.8% respectively.[7] Researchers found that usage of mobile apps strongly correlates with user context and depends on user's location and time of the day.[8] Mobile apps are playing an ever-increasing role within healthcare and when designed and integrated correctly can yield many benefits.[9][10]
All apps targeted toward a particular mobile platform are known as native apps. Therefore, an app intended for Apple device does not run in Android devices. As a result, most businesses develop apps for multiple platforms.
While developing native apps, professionals incorporate best-in-class user interface modules. This accounts for better performance, consistency and good user experience. Users also benefit from wider access to application programming interfaces and make limitless use of all apps from the particular device. Further, they also switch over from one app to another effortlessly.
The performance of these apps is similar to a web application running in a browser, which can be noticeably slower than the equivalent native app. It also may not have the same level of features as the native app.
These are made to support web and native technologies across multiple platforms. Moreover, these apps are easier and faster to develop. It involves use of single codebase which works in multiple mobile operating systems.[citation needed]
Developing apps for mobile devices requires considering the constraints and features of these devices. Mobile devices run on battery and have less powerful processors than personal computers and also have more features such as location detection and cameras. Developers also have to consider a wide array of screen sizes, hardware specifications and configurations because of intense competition in mobile software and changes within each of the platforms (although these issues can be overcome with mobile device detection).
Mobile application development requires the use of specialized integrated development environments. Mobile apps are first tested within the development environment using emulators and later subjected to field testing. Emulators provide an inexpensive way to test applications on mobile phones to which developers may not have physical access.[13][14]
Google Play (formerly known as the Android Market) is an international online software store developed by Google for Android devices. It opened in October 2008.[19] In July 2013, the number of apps downloaded via the Google Play Store surpassed 50 billion, of the over 1 million apps available.[20] As of September 2016, according to Statista the number of apps available exceeded 2.4 million. Over 80% of apps in the Google Play Store are free to download.[21] The store generated a revenue of 6 billion U.S. dollars in 2015.
Apple's App Store for iOS and iPadOS was not the first app distribution service, but it ignited the mobile revolution and was opened on July 10, 2008, and as of September 2016, reported over 140 billion downloads. The original AppStore was first demonstrated to Steve Jobs in 1993 by Jesse Tayler at NeXTWorld Expo[22] As of June 6, 2011, there were 425,000 apps available, which had been downloaded by 200 million iOS users.[23][24] During Apple's 2012 Worldwide Developers Conference, CEO Tim Cook announced that the App Store has 650,000 available apps to download as well as 30 billion apps downloaded from the app store until that date.[25] From an alternative perspective, figures seen in July 2013 by the BBC from tracking service Adeven indicate over two-thirds of apps in the store are "zombies", barely ever installed by consumers.[26]
Mobile application management (MAM) describes software and services responsible for provisioning and controlling access to internally developed and commercially available mobile apps used in business settings. The strategy is meant to off-set the security risk of a Bring Your Own Device (BYOD) work strategy. When an employee brings a personal device into an enterprise setting, mobile application management enables the corporate IT staff to transfer required applications, control access to business data, and remove locally cached business data from the device if it is lost, or when its owner no longer works with the company. Containerization is an alternate approach to security. Rather than controlling an employee/s entire device, containerization apps create isolated pockets separate from personal data. Company control of the device only extends to that separate container.[36]
Especially when employees "bring your own device" (BYOD), mobile apps can be a significant security risk for businesses, because they transfer unprotected sensitive data to the Internet without knowledge and consent of the users. Reports of stolen corporate data show how quickly corporate and personal data can fall into the wrong hands. Data theft is not just the loss of confidential information, but makes companies vulnerable to attack and blackmail.[37]
Alternatively, it is possible to offer native apps securely through enterprise mobility management. This enables more flexible IT management as apps can be easily implemented and policies adjusted at any time.[41]
Office is produced in several versions targeted towards different end-users and computing environments. The original, and most widely used version, is the desktop version, available for PCs running the Windows and macOS operating systems. Microsoft also maintains mobile apps for Android and iOS. Office on the web is a version of the software that runs within a web browser.
Word, Excel, and PowerPoint on the web can all natively open, edit, and save Office Open XML files (docx, xlsx, pptx) as well as OpenDocument files (odt, ods, odp). They can also open the older Office file formats (doc, xls, ppt), but will be converted to the newer Open XML formats if the user wishes to edit them online. Other formats cannot be opened in the browser apps, such as CSV in Excel or HTML in Word, nor can Office files that are encrypted with a password be opened. Files with macros can be opened in the browser apps, but the macros cannot be accessed or executed.[25][26][27] Starting in July 2013, Word can render PDF documents or convert them to Microsoft Word documents, although the formatting of the document may deviate from the original.[28] Since November 2013, the apps have supported real-time co-authoring and autosaving files.[29][30]
The Personal edition of Office on the web is available to the general public free of charge with a Microsoft account through the Office.com website, which superseded SkyDrive (now OneDrive) and Office Live Workspace. Enterprise-managed versions are available through Office 365.[34] In February 2013, the ability to view and edit files on SkyDrive without signing in was added.[35] The service can also be installed privately in enterprise environments as a SharePoint app, or through Office Web Apps Server.[24] Microsoft also offers other web apps in the Office suite, such as the Outlook Web App (formerly Outlook Web Access),[36] Lync Web App (formerly Office Communicator Web Access),[37] Project Web App (formerly Project Web Access).[38] Additionally, Microsoft offers a service under the name of Online Doc Viewer to view Office documents on a website via Office on the web.[39]
