When you create an App with Appy Pie the sizes of the app could vary from 5mb to 50mb, this happens as a result of images you use in the app, which is accounting for 31% of the entire app’s size, with code (14%), fonts (6%) and audio and video plugins (49%). Within the “plugins” category are around a dozen different SDKs, and as and when you add more features to your app new sdks are added which directly impact your app Size. So in simple words Apps with minimalistic features and images will be a lot lighter when compared to an app that has tons of features and multimedia content.
