In Q1 2018, Android tablets had 62% of the market, Apple's iOS had 23.4% of the market and Windows 10 had 14.6% of the market. In late 2021, iOS has 55% use worldwide (varies by continent, e.g. below 50% in South America and Africa) and Android 45% use. Still, Android tablets have more use than iOS in virtually all countries, except for e.g. the US and China.
