App development for iOS and Android differs in several crucial ways:
Android app developers use Java or Kotlin, while iOS app developers use Swift.
There is a standard screen size for iPhones and iPads with Apple devices. Due to the wide variety of screen sizes, Android devices require more attention to interface design to be compatible and functional on various devices.
It is more difficult to develop Android apps because of the fragmentation of devices resulting from the number of Android versions. Maintaining and developing Android apps is more challenging since different devices receive security updates at different times.
The user demographics of iOS and Android apps differ based on age, income, hours spent on apps, location, etc. There is a trend towards younger and more affluent Apple users compared to Android users.
