# Choose Between a Web App and a Mobile App

One of the first design decisions you need to make when creating an application in ONEWEB is choosing **the type of application** you want to build.\
This decision has a direct impact on **user experience, performance, deployment model, and available platform capabilities**.

Under the **App Design Fundamentals**, this section helps you understand the differences between **Web Apps** and **Mobile Apps**, and guides you in choosing the right option based on your project requirements.

#### What Is a Web App?

A **Web App** is a browser‑based application that runs on any device with a web browser.\
It uses a **responsive design** to adapt its layout and user experience across different screen sizes, including desktops, laptops, tablets, and mobile devices.

Key characteristics of a Web App:

* No installation is required; users access the app via a URL
* Works across multiple devices and platforms
* Well‑suited for applications that display or manage **large volumes of data**, such as tables, forms, and dashboards
* Ideal for internal systems, back‑office tools, and desktop‑centric workflows

#### What Is a Mobile App?

A **Mobile App** in ONEWEB is built using a **hybrid application model**, typically powered by a framework such as **Apache Cordova**.

Mobile Apps provide a **mobile‑optimized user experience** and can access device‑specific features through plugins.

Key characteristics of a Mobile App:

* Installed directly on mobile devices
* Optimized for touch interactions and mobile UI patterns
* Can access device capabilities such as camera, storage, and sensors
* Supports **offline usage** and local data caching
* Uses a single codebase that can run on both **iOS and Android**

#### Web App or Mobile App: How to Decide?

Choosing between a Web App and a Mobile App depends on **how the application will be used**, not just how it will be built.

The table below highlights key differences to help guide your decision.

| Design Consideration      | Web App                                      | Mobile App                                        |
| ------------------------- | -------------------------------------------- | ------------------------------------------------- |
| **Code Reusability**      | Single codebase for all browsers and devices | Single codebase for supported mobile platforms    |
| **Execution Environment** | Runs in a web browser                        | Runs as an installed mobile application           |
| **User Experience**       | Responsive UI for various screen sizes       | Mobile‑optimized UI and interactions              |
| **Performance**           | Depends heavily on network connectivity      | Optimized for mobile, reduced server round‑trips  |
| **Device Capabilities**   | Limited to HTML5 browser features            | Full access via device plugins                    |
| **Offline Support**       | Limited, requires additional components      | Built‑in offline and local storage support        |
| **Deployment & Updates**  | Updated automatically on browser refresh     | App update required only for native shell changes |
| **Distribution Model**    | Access via URL                               | Distributed via in‑house or app stores            |

#### Design Guidance

As part of **App Design Fundamentals**, consider the following when choosing:

* Choose a **Web App** when:
  * Users primarily work on desktops or laptops
  * The app manages complex data or forms
  * Fast access and easy updates are important
* Choose a **Mobile App** when:
  * Users work primarily on mobile devices
  * Offline access is required
  * Device features enhance the user experience

In some cases, organizations may choose to build **both**, starting with a Web App and later extending to a Mobile App as requirements evolve.
