iOS
Apple's mobile operating system for iPhone and iPad, with its own App Store and a tightly integrated hardware software combination.
Also known as: Apple iOS, iPhone Operating System
iOS is Apple's mobile operating system for iPhone and iPod touch. On iPad, the variant is called iPadOS, but it shares most of the technical foundation. The system stands for tight integration of hardware and software, clear interaction concepts and a curated App Store where all apps are reviewed before publication.
Market and distribution
iOS has a market share between 20 and over 50 percent depending on region. In the US, the UK and Japan, Apple is strong, while many other markets are dominated by Android. Updates reach a large share of active devices quickly, so new features are widely available faster than on many Android variants. This matters for developers and advertisers.
Privacy and advertising
Apple has introduced several features in recent years that strongly influence advertising. App Tracking Transparency allows tracking only with explicit user consent. Mail Privacy Protection preloads images and makes classic open measurement less reliable. Anyone working in mobile marketing should review iOS behaviour patterns regularly because Apple rolls out features often with major system updates.
Context in daily marketing
In day to day marketing, iOS features mainly affect measurement values. Open rates in JD Mail can appear higher than actual attention due to Mail Privacy Protection. Clicks remain the more reliable signal. A conscious choice of metrics avoids misinterpretation. Content and openers should work independently of tracking and deliver a clear value promise.
