Defining mobile app accessibility requirements before a single line of code is written saves significant rework and ensures your product works for users with visual, motor, or cognitive disabilities from day one. Getting this right matters especially in India, where assistive technology adoption and government procurement standards are both growing.
Mobile App Accessibility: What to Clarify Before You Write a Brief
Accessibility is not a feature you bolt on at the end of a project. When teams treat it as optional polish, they discover late in development that navigation hierarchies, interactive element labels, and layout structures need fundamental changes rather than surface-level tweaks. The scope of that rework—in developer hours, QA cycles, and delayed launches—consistently exceeds what early scoping would have addressed.
Before briefing any development partner, product teams should decide which disability categories their app must serve: visual impairment, low vision, motor impairment, hearing impairment, or cognitive accessibility needs. Each category drives different technical requirements. Defining the target scope upfront lets you prioritise correctly rather than discovering gaps during user acceptance testing. A useful starting point is the W3C Web Accessibility Initiative's introduction to accessibility, which explains the range of barriers that poor design creates.
Screen Reader Compatibility, Focus Order, and Touch Target Requirements for Android and iOS
TalkBack on Android and VoiceOver on iOS are the two dominant screen reader technologies your Indian users are likely to have installed. Both require every interactive element—buttons, form fields, icons used as controls—to carry a meaningful semantic label. An icon button with no content description is silent to a screen reader user and effectively invisible to them. This is not something that can be patched with a single find-and-replace pass; it must be designed into the component architecture from the start.
Focus order determines the sequence in which a screen reader moves through your interface. If a modal opens but focus remains on the content behind it, users relying on TalkBack or VoiceOver are trapped. Touch targets are equally important: elements smaller than 44×44 density-independent pixels exclude users with motor impairments and fail basic accessibility heuristics on both platforms. Ask your development partner explicitly: what minimum touch target size will the component library enforce, and how will focus management be handled for modals and drawers?
Content Scaling, Colour Contrast, and Low-Vision Use Cases in Indian App Design
Low-vision users frequently increase the system font size on their devices. If your app's layout breaks or text overflows its container at 150% or 200% scale, a significant portion of your users will struggle with basic tasks. Scoping this means agreeing on minimum and maximum text size multipliers that the interface must support and testing layouts across those ranges before the UI is approved for production.
Colour contrast requirements apply across every theme variant your app ships with, including dark mode. A colour combination that passes a contrast ratio check in light mode may fail in dark mode if the palette is simply inverted without recalculating foreground-to-background ratios. In Indian app design contexts—where apps often span diverse lighting conditions and device quality ranges—validating contrast across themes is a concrete deliverable, not an assumption. Request that your design specifications include contrast ratio documentation for each theme.
Assistive Technology Testing Environments and What to Request From Your Dev Partner
Automated accessibility scanners catch a subset of problems—missing labels, inadequate contrast, improper heading structure—but they cannot replicate the actual navigation experience of a screen reader user. A scanner will not tell you that a custom gesture conflict makes a carousel unusable with TalkBack, or that a dynamic content update is announced at the wrong point in a conversation flow. Real assistive technology testing, on physical devices with actual screen readers enabled, should be a named workstream in your project plan.
When scoping with a development partner, ask whether accessibility testing will be performed by developers self-checking during build, by a dedicated QA engineer with assistive technology experience, or ideally as a UAT workstream involving users who rely on these tools. In the Indian market, recruiting testers who actively use TalkBack or VoiceOver is feasible and produces qualitatively different feedback than internal review alone. Confirm which devices and OS versions will be included in the test matrix before the project starts.

Defining Mobile App Accessibility Requirements in a Project Brief for Indian Markets
An accessibility section in a project brief should cover at least four items: the conformance standard you are targeting (WCAG 2.1 Level AA is a common baseline), the disability categories in scope, the platforms and OS versions to be tested, and whether assistive technology user testing is included in the UAT phase. Indian government procurement guidelines increasingly reference accessibility standards, making this section relevant not only for inclusive design goals but also for eligibility in certain tender processes—worth confirming with your legal or procurement team independently.
Beyond the brief itself, accessibility requirements need to appear in your definition of done for each sprint or milestone. If a component can be merged without passing basic screen reader checks, it will not be caught until integration testing reveals systemic issues. Agree with your development partner on whether accessibility review is a gate in the development workflow or a separate audit at the end. The former requires substantially less rework to execute because issues are identified at the component level before they compound across the full product. Teams building Indian-market products can browse the iJurug Soft blog for related guidance across product categories and technology decisions.
If you are scoping a new mobile product or retrofitting accessibility into an existing app, iJurug Soft's services cover mobile app development where accessibility requirements can be defined as part of the project brief from the outset. Bring specific questions about platform targets, user groups, and testing requirements to an initial conversation.
Frequently Asked Questions
Is WCAG applicable to mobile apps or only to websites?
WCAG 2.1 principles apply to mobile apps and are referenced in platform-specific guidance from both Google and Apple. The success criteria map to native app components, including touch targets, colour contrast, and programmatic labels on interactive elements.
How do I know if my existing app has accessibility gaps before a full audit?
Enable TalkBack or VoiceOver on a test device and navigate your app without looking at the screen. Unlabelled elements, broken focus order, and inaccessible custom components become immediately apparent through this simple heuristic review before a formal audit begins.
Should accessibility requirements differ for Hindi-language or regional-language app interfaces?
Yes. Screen reader pronunciation and text expansion behaviour vary by language. Regional scripts may require larger minimum touch targets and additional contrast testing, particularly if fonts render at smaller effective sizes than their Latin equivalents at the same point size.
