Android-iOS rivalry

The rivalry began when Apple launched the iPhone running iPhone OS in 2007, followed by the first commercially available Android phone, the T-Mobile G1 (HTC Dream), in 2008. Google had acquired Android Inc. in 2005 and developed the platform as an open-source alternative to Apple's closed ecosystem. The two operating systems have dominated the global smartphone market ever since.

Android consistently holds the majority of global smartphone market share, often exceeding 70 percent, largely because it runs on devices from manufacturers like Samsung, Xiaomi, and Google. iOS, exclusive to Apple hardware, holds a smaller global share but leads in markets like the United States and among higher-income demographics. The split varies significantly by region and price segment.

iOS apps are distributed exclusively through Apple's App Store, which enforces strict review guidelines and charges up to a 30 percent commission on paid apps and in-app purchases. Android apps are distributed primarily through Google Play, which has historically had more relaxed policies, and can also be sideloaded from third-party sources. Both stores host millions of apps, though iOS has traditionally generated more developer revenue.

Switching is possible but involves some friction, as Apple and Google offer migration tools like Apple's 'Move to iOS' app and Google's backup services to transfer contacts, photos, and messages. However, paid apps and some subscription services do not transfer between platforms. Both companies have progressively improved their migration tools in recent years to reduce switching barriers.
