Their main function is solve specific needs of people in a simple, intuitive and personalized way, taking advantage of the technical capabilities of the device.

How have mobile apps evolved? A brief history and expansion
The rise of apps is linked to the development of modern mobile operating systems. The first "mobile" apps in history were simple programs included with classic phones: address books, ringtone editors, games like Snake or Tetris… Their purpose was very basic, but they paved the way for what was to come.
The big leap came with the appearance of platforms like iOS (Apple) and Android (Google), who introduced the concept of app store and enabled millions of developers to publish and monetize their own ideas. The ability to access thousands of specialized tools with a single tap revolutionized the market and fostered healthy competition to offer more innovative and useful solutions.
Nowadays, No current smartphone comes onto the market without a pre-installed app store. and a selection of basic apps to get you started using the device. The available app catalog is immense, with offerings in every imaginable field and a variety that grows daily.
How does an app work on a mobile phone?

That is, although it seems like you're "downloading the app to your phone," it's technically integrated into the operating system layer to manage its permissions, access, and resources.
Each operating system (OS) has its own distribution format and APIs for apps to communicate with the hardware and other software. Therefore, An app designed for Android does not work directly on an iPhone and vice versa.And if you had two operating systems on your device, you'd need the specific version for each one.
During installation, the app asks you for permissionsFor example, WhatsApp requires access to your contacts and media files, while a camera app will ask for access to your camera and storage. The operating system manages these accesses to protect your privacy. and allows you to configure them according to your preferences.

- Download and installation: from the corresponding app store.
- Permit request: The app tells you what data or functions of the device it needs to access.

- Processing and execution: The app performs its function, using resources (network, GPS, sensors…).
- Updates: Periodically, stores and developers release new versions that improve security, performance, or add new features.
How many types of mobile apps are there? (Native, web, hybrid, etc.)
In the mobile universe, not all apps are the sameDepending on how they are developed and executed, there are several main types:
- Native apps: They are programmed exclusively for a specific operating system (Android, iOS, etc.) using specific language and tools. They are installed directly on the device and access all its functions, giving them greater performance, fluidity, and the ability to work offline.
- Web Apps: They don't require installation on the device, as they function as a mobile-friendly website. You access them through a browser (Chrome, Safari, etc.) and they're usually lighter, although they depend on an internet connection and can be less powerful than native apps.
- Hybrid apps: They combine both concepts. They are developed using web technologies (HTML, CSS, JavaScript) and are "packaged" so they can be installed like a normal app from the app stores. Many popular services first release a hybrid version to quickly reach all systems, although they tend to offer less performance optimization than native versions.
Each type has advantages and disadvantages. Native apps are usually faster and make better use of mobile features; web apps take up little space and update automatically; hybrid apps allow you to run on many systems at a lower cost.
