Mobile Application: A mobile application, most commonly referred to as an app, is a type of application software designed to run on a mobile device, such as a smartphone or tablet computer. E.g. google classroom, photo math, etc. Three Types of Apps: Native, Hybrid, and Web Native mobile apps: Native mobile apps are designed to be “native” to one platform, whether it’s Apple iOS, Google’s Android, or Windows Phone. An android cannot be used on an iOS phone and vice versa. Hybrid mobile apps: These apps can be installed on devices just like native apps, but they run through web browsers. All hybrid apps are developed through the HTML5 programming language. It’s ideal for apps that primarily deliver content. Web apps: Responsive websites switch to a different design when they are accessed from a mobile device. Web apps are built using the most popular programming languages, but they can’t use hardware on mobile devices or be sold in any app store.
