According to the explanation, the main reason iPhone apps seem to have an edge over their Android versions is because there are fewer options on the market. People can see a lot of Android phones with different capabilities, processors, screens, cameras, etc. However, Apple only produces a handful of iPhone models to choose from.
Although Apple has expanded the number of models, they are all high-end devices that can take advantage of the most demanding applications for years to come. Vonau admits Google's apps are also better on the iPhone.
“Google Maps builds its routes on the fly, giving users a sense of movement. WhatsApp provides appropriate transitions when the user opens the keyboard or swipes to go back to all chats. And YouTube provides rich, stretched animations when users move their phones to landscape mode," Vonau wrote.
Another point Vonau makes is that iOS gesture navigation has been the default since the iPhone X, while Android phones offer different methods. For example, depending on the phone, going back can be done with the back button, back gesture, or customization from the device manufacturer.
Though Vonau doesn't mention it, iPhone owners are more likely to pay for an app or in-app subscription than Android owners. Statista has a graph that shows how much people spend on the App Store and Google Play Store and how much they will pay in the future, with the difference noted to be huge.
As a result, developers make better apps for iPhone users because more revenue will come to them, even if the Android user base is larger.
