iOS v. Android: Mobile Accessibility Features

Published August 12, 2021

Android and iOS have helped revolutionize the world of mobile communication technology. In 2019, it is estimated that 2.7 billion people owned a smartphone. Of those 2.7 billion users, approximately 15% are estimated to live with at least one disability. Since handheld devices and mobile operating systems have begun to replace traditional desktop computers, providers are working continuously to improve the accessibility of their products for users with disabilities. Here we list some of the most user-friendly accessibility features of both these systems and how they are helping people who need to use assistive technologies access the web.

iOS v. Android accessibility: which is better?

In general, the number of Android users far exceeds the number of iOS users worldwide. However, at least one survey showed that slightly more people with vision or motor limitations preferred iOS to Android. In that study, roughly 18.5% of users reported a preference for iOS over Android (16.5%). However, the right choice is likely the one that fits your needs and budget.
