Mobile accessibility options are the accessibility features built into iOS and Android, including VoiceOver, TalkBack, text scaling, high contrast, reduced motion, and switch access, which people turn on at the operating system level and expect every app to respect. Below, we’ll cover the options that matter most on each platform, what each one changes on-screen, and how to design so your app still works when they’re enabled.

Someone opens your app with VoiceOver running, text scaled well past the default, and Reduce Motion switched on. They set those preferences on their phone long before they download your app, and the settings apply to everything they open.
What happens next depends almost entirely on the decisions your team made before launching the app. If controls were labeled, VoiceOver announces them. If the layout was built to reflow, the larger text fits. If the app checks the motion preference, the transition simplifies. Miss any of it, and they can’t complete what they came to do, even though every setting on the user side is working exactly as intended.
That gap is where most mobile accessibility features live. Not in the features themselves, which Apple and Google have built well, but in the space between a setting being enabled and an app being ready for it.
What Mobile Accessibility Options Are
Mobile accessibility options are device-level settings that change how a phone presents and accepts information, and because they are set at the OS level, they apply to every app someone opens.
They fall into a few broad groups. Screen readers announce what is on screen for people who cannot see it. Magnification and text scaling change how large the content renders. Contrast and color setting change how it is colored. Motion settings suppress animation. And alternative input methods, including switch access and voice control, replace touch entirely.
The Accessibility Options that Matter Most
iOS and Android offer equivalent accessibility options under different names, and each one changes something specific about how your interface is presented or controlled.
The table below maps the settings people rely on most, what each one changes on screen, and what your app has to do for it to work.
Two patterns show up in what your app has to do. Most of the work is the same on both platforms, so an app built properly for one is usually most of the way there on the other. And nearly all of it has to happen before launch, because these settings can only work with what your app already exposes to them.
Quick summary
What Developers Should Prioritize
Building for accessibility options comes down to four things: adaptable layouts, accessible input, labeled elements, and respecting the preferences people have already set.
Support adaptability with responsive layouts and dynamic text sizing, so content reflows instead of truncating.
Ensure accessible input methods, from touch and voice to switch access, with an alternative for every gesture.
Label every interactive element with a meaningful name, role, and state, since screen readers and voice control both depend on it.
Respect system-level preferences for motion, contrast, and text size rather than overriding them.
Where Testing Fits
Once these elements are in place, the next step is confirming they work on an actual device. That takes platform-level automated checks and hands-on passes with VoiceOver and TalkBack, which we cover in our guide to mobile accessibility testing.

Mobile accessibility options only work when an app gives them something to work with. A screen reader needs names to announce. A layout needs room to reflow. A transition needs a simpler version to fall back on. Get the four priorities right above, and the accessibility settings people have already chosen finally do what they promise. None of it shows up in a design review, which is why these decisions belong in the build rather than in a fix after someone complains.
That’s where AudioEye fits in. AudioEye’s Mobile Audits test the interfaces, functionality, and user experience of your iOS and Android apps. By combining automation with Expert Audits, AudioEye achieves roughly 97% issue coverage — more than any other tool on the market. Accessibility also has to hold as the app changes. Our Accessibility Testing SDK runs these checks inside your CI/CD workflow, so missing labels and rigid layouts get caught before they ship, and Active Monitoring keeps watching after launch as your app evolves.
