The smartphone operating system market is dominated by two platforms: Android and iOS. Globally, Android usually holds a majority of unit share (often around 70–75%), while iOS holds a smaller but highly valuable share (around 25–30%). The exact numbers vary by source and by whether share is measured in units shipped, active devices, or revenue. Statcounter, IDC, and similar sources are commonly used for these estimates; regional data can differ sharply—for example, iOS share tends to be higher in North America and Japan, and lower in Asia and Africa.
For developers, the OS split informs which platforms to prioritize and where to focus localization. For consumers, it reflects the mix of devices in their region and the availability of apps and services. Over time, Android’s share has grown in many emerging markets due to a wide range of price points, while iOS remains strong in mature markets and premium segments.
