Orbital Survey

iOS Versions Market Share in 2025

Which major system versions of iOS are used the most?

This chart shows the top major versions of the iOS operating system for each week in the last year. Values are percentages.

For the purposes of this survey, iOS also includes iPadOS, so this data is from iPads as well as iPhones. However, other spin-offs of iOS such as tvOS or watchOS are not included in this chart.

Some interesting observations are:

  • After its launch in September 2024 iOS 18 had by far become the version with the highest share. It was at over 87% at the end of August 2025. Its share has started decreasing though and was at 64.19% at the end of September.
  • iOS 19 and iOS 26 are in general the same version of iOS with differences in development environments used in building the app. For that reason, iOS 19 is most likely still to be reported for an extended period of time. For this survey the sum of iOS 19 and iOS 26 is taken and displayed as iOS 26. Digging deeper into the ratio between iOS 19 and iOS 26, at the end of September iOS 26 was responsible for over 99% of the accumulated value displayed in this chart.
  • After the official launch of iOS 26 the combined total of iOS 19 and iOS 26 has jumped in three weeks from less than 5% to 29.32% at the end of September.
