iOS Versions Market Share in 2026

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 over the next 12 months. It was at over 87% at the end of August 2025. Its share had decreased since then but was still the most used version with over 53% at the end of November. After a push of iOS 26 the share of iOS 18 had decreased to less than 40% as of end of 2025. In 2026, the share has continued to decline and was at 7.09% at the end of September 2026.
• 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 had jumped in three weeks from less than 5% to over 29% at the end of September 2025. In October and November, the increase was rather moderate, and the share was at around 40.50% as of the end of November. After the push in December mentioned above the share of iOS 26 had risen to around 55% at the end of 2025. In 2026, the increase has continued and the share peaked at around 86.50% at the end of August and beginning of September. As the share of iOS 27 has been increasing since then, the share of iOS 26 has decreased to 74.58% at the end of September.
• the share of iOS 27 did not change much for a couple of month and was at around 3%. Since the official launch in September, it increased notably to 16.27% at the end of the month. See the link below for more detailed insights.
