Discover the 3 Types of Apps You Need to Know About

Mobile apps are an integral part of our daily lives, driving a substantial portion of our online interactions. With over 218 billion app downloads projected globally in 2024, understanding the different types of mobile apps is essential for businesses looking to develop their own. 

There are three main types of mobile apps: native, web, and hybrid. 

Each type has its unique features, benefits, and limitations. This article explains these distinctions clearly, helping you decide which type of app best suits your business needs. 

By understanding the nuances of each, you can better navigate the app development process and select the right approach for your goals.

What Is an App?

An app is a self-contained software package that helps users perform specific tasks on mobile or desktop devices. Apps can be pre-installed on devices or downloaded from app stores like the Apple App Store.

Apps are created using different programming languages. For example, Android apps are made with Kotlin, Java, and C++, while iOS apps use Swift and Objective-C within the Xcode development environment. 

These apps are packaged into files like APK for Android and IPA for iOS, including all the necessary code, data, and resources to run the app.

Key Components of an App

1. Activities

An activity is the main entry point for users. It is displayed through a user interface (UI) and allows users to interact with the app. 

For instance, in a social media app like Instagram, one activity might show user-recorded videos, another could offer options to create posts, and another might display posts from other users. 

While these activities work together to provide a smooth user experience, each one operates independently.

2. Services

A service runs in the background and performs tasks without a user interface. For example, a music app might use a service to play songs while the user does other things on their device. 

Services ensure that background tasks continue to function even when the user is not directly interacting with the app.

3. Broadcast Receivers

Broadcast receivers allow an app to respond to system-wide announcements or events. For example, a reminder app can alert you about an upcoming event without needing to stay active all the time. Broadcast receivers let the app react to events like alarms or notifications even when it’s not currently running.

4. Content Providers

Content providers manage and share data between apps. They allow apps to store data in a centralized location that other apps can access with permission. For example, a content provider might link different apps to a shared database, enabling them to query or modify data as needed.

5. App Resources

Apps use various resources beyond the source code, such as images, audio files, and other visual elements. These resources allow users to customize and optimize the app for different devices and preferences. 

For example, an app might have different layouts for different screen sizes or languages, all defined using XML files. These resources help make the app adaptable to various device configurations.

These components are crucial as they enable apps to be flexible and functional across different devices and use cases.

How Do Apps Function?

Apps allow users to interact with them through a user interface (UI), which is part of the app’s front end. The front end processes the user’s request and sends it to the backend. Both the front end and back end are important without a working back end, the front end can’t function effectively, and vice versa.

The frontend and backend communicate via APIs (Application Programming Interfaces). Let us take an example to understand this better. 

Consider the e-commerce app ‘eBay’ which uses Google Cloud to provide e-commerce services. If a user wants to buy a winter jacket, they tap the ‘buy now’ button and proceed to the checkout page to choose a payment option. 

Here, the eBay frontend sends the user’s request to the backend servers, which connect to the payment gateway.

In this case, the API facilitates two-way communication between the front end and back end. It also connects to the external payment provider, displaying the payment page for the user. The API ensures the app remains active until the transaction is complete, allowing the user to make the purchase.

The backend is the ‘brain’ of any mobile app, handling data processing, storage, and security. For example, retrieving the jacket selected by the user from the database is the backend’s job. The backend runs on remote servers and delivers app features to the user via APIs.

The backend extends app functionality beyond the capabilities of a typical smartphone, providing a seamless frontend experience without having a user interface itself. It enables communication between devices and servers, ensuring a smooth user experience.

These types allow you to create a functional app more quickly, which is ideal for smaller teams or projects with tight deadlines.

2. Enhance User Experience with App Performance

App performance is essential for delivering a smooth and satisfying user experience. For applications that demand high performance, such as games or resource-intensive tools, native apps are the best choice. They offer better optimization and access to device-specific features, ensuring a more responsive and reliable user experience.

3. App Development Cost

The cost of app development varies significantly based on the app type. Native apps tend to be more expensive due to the need for separate development for each platform. If budget constraints are a concern, hybrid apps or Progressive Web Apps (PWAs) can be more cost-effective alternatives. These options allow you to build a single app that works across multiple platforms, saving time and money.

Which One Should You Choose?

When deciding which type of mobile app to create, consider what’s most important to your project right now. The right choice depends on your current needs and constraints.

1. Need an App Quickly?

If you need an app as soon as possible, go for a web app. It can be developed fast and accessed through any mobile browser, saving you time and getting your app to users quickly.

2. Limited Resources?

If you’re short on time and money, consider a web app or a hybrid app. A hybrid app allows you to create a basic version quickly and test the market. If it’s successful, you can later develop a native app.

3. Performance is Key?

If you need your app to be fast and reliable, a native app is the best choice. It offers the best performance, stability, and customization, ensuring a smooth experience for your users.

Remember, the type of app you choose now doesn’t have to be permanent. You can always develop other types later based on user feedback and needs.
