App developers aim to create apps that cater to the needs of different types of users. This development approach, also known as the "one-size-fits-all" strategy, involves combining various functionalities into one app. However, this approach has drawbacks, such as lower conversion rates, slower download speed, larger attack surfaces, and lower update rates. To address these issues, developers have created "lite" versions to attract new users and enhance the user experience. Despite this, there has been no study conducted to examine the relationship between lite and full apps. To address this gap, we present a comparative study of lite apps, exploring the similarities and differences between lite and full apps from various perspectives. Our findings indicate that most existing lite apps fail to fulfill their intended goals (e.g., smaller in size, faster to download, and using less data). Our study also reveals the potential security risks associated with lite apps.
