Why are iOS Apps Bigger than Android?

App Size Comparison

Have you ever wondered why iOS apps tend to be larger in size compared to their Android counterparts? This has been a question that has puzzled many people, especially those who own iPhones or iPads. In this article, we will explore the reasons behind this phenomenon.

iOS and Android Architecture Differences

One of the main reasons why iOS apps are bigger than Android apps is due to the differences in their architecture. iOS uses a different architecture compared to Android, making it more difficult to compress the code in iOS apps. Furthermore, iOS apps are built for a specific set of processors and screen sizes, which means the apps need to include all the necessary resources to run on each of these devices.

To further understand this, let’s take the example of a video game. When developers create a game for iOS, they have to create a separate version for each device that is compatible with the game. As a result, the game will have to include all the resources required to run on each device, leading to a larger app size.

iOS Apps Require More Resources

iOS Android
Requires more resources to run apps Requires less resources to run apps
Apps are optimized for specific devices Apps are optimized for different devices
Architecture is less flexible Architecture is more flexible

iOS apps require more resources to run compared to Android apps. For instance, iOS apps require more memory and have higher graphics and processing requirements. This means that developers have to include all these resources in the app, leading to a larger app size.

Furthermore, iOS apps are optimized for specific devices, which means that they have to include all the necessary resources required for each device. This is different from Android, where developers can optimize the app for a range of devices, resulting in smaller app sizes.

iOS Apps are More Secure

iOS has a reputation for being more secure compared to Android. As a result, Apple has implemented security measures and policies that make iOS apps more secure. This means that iOS apps have to include additional security features, leading to larger app sizes.

Furthermore, Apple requires developers to include specific features in their apps, such as sandboxing, which ensures that apps do not interfere with each other. This, in turn, adds to the app’s size.


In conclusion, iOS apps tend to be larger compared to Android apps due to the differences in architecture, required resources, and security measures. However, this does not mean that iOS apps are worse than Android apps. Instead, it is just a result of the operating systems having different approaches to app development.
