If you are looking to cover a wider market, you should go with Android platform for your next app development.
But, even though the number of Android apps and users is higher, Apple App store generates much more revenue than its competitor.
Android has its own open development platform which also supports many third-party apps and tools, which is a wonderful thing for developers as they can try out many features and add more functionality to their apps.
Apple also provides a development platform along with a limited set of tools, but developers cannot use any external tool for development, which makes it harder for them to experiment new things.
Android apps may cost more because of the extensive range of devices and platforms, but it is a good thing that Android Studio (development platform) can work on any modern PC, as opposed to Apple’s Xcode development platform, which only works on Mac systems.
The Android Apps are generally written in JAVA, and IOS application is written in the Swift Language. many of the developers choose IOS over the Android just because of money, the Complexity of iOS app development is less complex compared to Android app development.
