Inclusive Design in HealthTech: How to Build Accessible UX/UI for Health Apps (2026)

Inclusive design in healthcare means building digital products that the widest possible range of people can use, including older, ill, stressed, and disabled users. In healthcare UX design, one inaccessible screen can block a dose reminder, a portal login, or a telehealth visit. The European Accessibility Act has applied since June 28, 2025, and US deadlines arrive in 2027 and 2028. This guide explains which rules apply to health apps in 2026 and how to design and test beyond them. It is written for HealthTech product owners, designers, and developers building accessible HealthTech UX/UI.

How Does an Aging Population Affect HealthTech UX/UI Design?

An aging population puts older patients at the center of HealthTech UX/UI design: they make up a growing share of the population and are less likely to use patient portals. The UN projects that one in six people will be over 65 by 2050, up from one in 11 in 2019. In the US, the 65+ share was 18% in 2024 and will reach about 22% by 2040.

Online medical records are offered more widely than they are used. In 2024, 77% of Americans were offered access, and 65% used it; older, lower-income, low-literacy, and limited-English patients used it less.

UX design for older adults in digital health starts from that usage gap. Accessibility rules cover part of it: they list what a health app must support, such as screen readers and readable contrast. Inclusive design and accessibility differ in scope: inclusive design also covers how patients use the product day to day. Accessibility requirements now carry legal deadlines in the EU and the US.

Which Accessibility Laws Apply to Health Apps in 2026?

Three laws define accessibility compliance in healthcare: the European Accessibility Act in the EU, and HHS Section 504 and ADA Title II in the US. All three build on WCAG, the technical standard for accessible digital products.

The US rules name WCAG 2.1 AA. WCAG 2.2 AA keeps nearly all WCAG 2.1 criteria and adds six new ones, making it the safer pick among accessibility guidelines for medical software.

The table shows which laws cover digital accessibility in medical apps and when each one applies.

Telehealth teams can add the WHO-ITU telehealth accessibility standard, published in 2022. Health apps that count as medical device software also fall under the EU Medical Device Regulation, which asks manufacturers to design for disabled users.

Which WCAG 2.2 Criteria Apply to Health Apps?

WCAG 2.2 added six A and AA criteria, and all six affect health apps, from dose buttons to login screens. Each belongs in medical UI/UX best practices.

WCAG 2.2 removed criterion 4.1.1 Parsing. Text contrast stays at 4.5:1 for normal text and 3:1 for large text.

What Are the Penalties for Inaccessible Health Apps?

Penalties range from lawsuits and funding risk in the US to national fines and distribution bans in the EU. US plaintiffs filed 3,117 federal web accessibility lawsuits in 2025, up 27% from 2,452 in 2024, accounting for 36% of Title III filings. Under HHS Section 504, the Office for Civil Rights investigates complaints, runs compliance reviews, and can refer cases to the Department of Justice. Federal funding can be at risk.

EU member states set their own fines through market surveillance authorities. Germany allows fines of up to €100,000. Spain allows up to €1 million for very serious infractions. Authorities can also restrict distribution or order recalls, and consumers can sue directly in Ireland and the Netherlands.

How Can HealthTech Teams Show Accessibility Compliance?

Teams show compliance with an accessibility statement, release audits, accessibility clauses in vendor contracts, and a log of fixes and retests.

Four recommended practices give auditors and regulators a clear record:

• Publish an accessibility statement with a contact route for barriers.

• Audit each release with automated and manual checks.

• Add accessibility requirements to vendor contracts, since the HHS rule covers vendors.

• Log fixes and retests so progress is documented.

What Do Accessibility Standards Miss in Health Apps?

Standards miss four areas: privacy flows, emergency access, device compatibility, and AI outputs. Each requires product decisions beyond a WCAG checklist, especially for assistive technologies in HealthTech.

• Privacy flows, such as consent screens and logins, must work with screen readers and keyboard navigation. GDPR requires explicit, informed, and unambiguous consent.

• Emergency flows should be reachable in a few steps, by voice and by assistive technology.

• Device compatibility needs its own testing, since health apps pair with screen readers, switch controls, and wearables. For hardware, start with connected medical device development.

• AI-generated text, summaries, and captions need the same accessibility checks as any other screen.

Does Inclusive Design Improve Patient Outcomes in Health Apps?

Patient portal use improves medication adherence, while results for clinical measures are mixed. A systematic review of 24 studies also found more use of preventive services, and the authors rated the evidence for blood pressure and glucose insufficient. Those gains depend on patients being able to log in, understand each screen, and complete tasks such as refills.

Most participants in those studies were English-speaking and highly educated, so the results may not apply to the groups that use portals least: older, lower-income, low-literacy, and limited-English patients. Product teams can fill that gap with their own data by tracking task completion and portal use for these groups. Those building HealthTech for chronic conditions can start with refill and reminder flows, since medication nonadherence is tied to $100–$300 billion in US health care spending each year.

How Do You Build Accessibility Into the HealthTech Design Process?

Accessibility work starts at discovery and continues in every sprint. Human-centered design in HealthTech begins with interviews of patients and clinicians, and the same groups then test prototypes. Co-design adds people who use assistive technology to the team, where they help shape flows and wording.

W3C recommends involving users throughout design and development and pairing their feedback with standards checks. Standards catch missing labels and low contrast. Users catch confusing flows and, sometimes, wrong product ideas: on Monterail's Camino smart walker project, user interviews dropped a planned patient dashboard because people wanted a seat, a fold-out rest point for when they got tired.

What Are the Best Practices for Healthcare UX Design?

The best practices for healthcare UX design combine WCAG limits with plain language and low-effort flows. They cover accessible design in healthcare, including UI for cognitive impairments.

For full flows, see Monterail's guide to healthcare app UX design with AI prototyping.

What Are Examples of Inclusive Design in Health Apps?

Five examples of inclusive HealthTech interfaces each remove one barrier: Apple's Personal Voice for speech loss, Medisafe reminders for chronic illness, Eargo's pairing flow for older users, the Dignity Project's hospital co-design, and live captions and telepresence for hearing and distance.

How Do Voice Interfaces Help Patients Who Risk Losing Speech?

Voice interfaces let patients who are losing speech keep communicating in their own voice. Apple's Personal Voice, announced in May 2023, was designed with conditions like ALS in mind. While they can still talk, they read prompts aloud for 15 minutes, and the iPhone builds a copy of their voice. Later, Live Speech lets them type a message and have it spoken in that voice during phone and FaceTime calls. The device creates the voice copy, which keeps the recording private. Spoken features in health apps rely on conversational design.

How Do Reminders Help Medication App Users?

Reminders help patients keep to their medication schedule. A 2025 JMIR Human Factors survey tested the medication reminder app Medisafe with 30 adults with chronic illnesses who receive care at a federally qualified health center in the northeastern US. After one month of use, all 30 agreed they would recommend it, and 28 strongly agreed the reminders helped them take medication on time. Five in six had government insurance, and the same share had two or more chronic illnesses. The randomized trial behind the survey found that app users had better medication adherence than those receiving usual care. Refill reminders went largely unused, often because participants already received pharmacy text alerts.

How Do Simpler Controls Help Older Device Users?

Simpler controls get older users through the hardest step, pairing the device, and let them adjust it day to day. Monterail's Eargo case study covers apps for FDA-regulated hearing aids designed for elderly, less tech-savvy users. Two weeks of research changed the project's direction before the team designed any screens. Target users included a 75-year-old first-time hearing aid user with limited technical literacy, possible motor limitations, and no experience pairing Bluetooth medical devices. The team built a custom pairing flow outside standard iOS and Android patterns, calibrated for older users and handling both ultrasonic and Bluetooth connections. Listening profiles and other simple mobile controls then let wearers adjust the device to different surroundings.

How Does Disability-Led Co-Design Work in a Hospital?

Disability-led co-design puts patients with disability in charge of naming problems and shaping solutions across a hospital stay. Griffith University and Metro South Health applied it in the Dignity Project. Planned for February 2023 to February 2025, it used a web platform where participants, particularly people with cognitive impairment, identified the main challenges at each stage of the patient journey. The aim was to co-design solutions for admission, inpatient care, and discharge at Metro South Health facilities. This is empathetic design in healthcare at hospital scale: the people affected shape the service from the start.

How Do AI and Telepresence Widen Access for Patients?

AI and telepresence widen access by removing barriers of hearing and distance. AI in accessible UX includes live captions and transcripts, which make video visits usable for people with hearing loss. The text still has to be clear, because users stop trusting recommendations they cannot understand. Telepresence predates AI: the PEBBLES system linked a hospitalized child to the regular classroom in real time via video conferencing, and the authors reported a very positive overall effect, strongest for that child.

What Are the Challenges of Implementing Inclusive Design in Health Apps?

Four challenges slow inclusive design in health apps: vendor integrations, low literacy and weak connectivity, language coverage, and testing with the right users. Planning for each one is part of designing accessible HealthTech apps.

Scope sets the budget. WCAG advises against requiring Level AAA as a general policy for entire sites, so a practical plan targets AA across the product and adds stricter checks only on high-stakes flows such as dosing, consent, and emergency access. Timing matters too: W3C cites a Forrester study commissioned by Microsoft that found accessibility can contribute to cost savings when it is part of ongoing development cycles.

Which Health App Integrations Need Accessibility Checks?

Every vendor screen in a patient journey needs a check. The HHS rule covers web content and apps provided through vendor contracts, so one inaccessible vendor screen can break the whole journey and the provider's compliance. The rule exempts third-party content only when it is posted outside a contract or license with the provider. Vendor-supplied scheduling, bill pay, and telehealth screens therefore belong in every audit, and vendor contracts should require WCAG 2.1 AA at minimum.

How Do Low Literacy and Poor Connectivity Change Health App Design?

Low literacy calls for plain wording and simple navigation, and weak connectivity calls for offline access. A 2014 National Academy of Medicine paper says plain language helps users find what they need, understand it, and act on it. The same paper advises consistent navigation, because users with low literacy can get confused or stuck without it. Offline functionality and syncing keep key features available without a stable connection.

How Do Language Differences Affect Health App Design?

Language shapes the first screen a patient sees. In an October 2025 JAMA Network Open study of 511 hospitals, 29% offered an English-only portal login, 60% offered English and Spanish, and 11% added one more language. Fewer than 5% offered the most common other language in their area.

The National CLAS Standards, 15 in total, cover culture, language, and health literacy. Standards 5 to 8 ask health organizations to offer language assistance and provide easy-to-understand digital and print materials in commonly used languages. For app teams, that points to translated login screens and plain-language text in every supported language.

How Should Teams Test Health Apps With Older Adults?

Run usability testing informally throughout development, starting with the prototype, instead of waiting for a final round. W3C suggests including a few people with disabilities and, depending on the audience, older users. It also advises matching assistive-technology skills to the audience, and a public-facing patient app calls for novice users. One participant cannot speak for everyone, so each round needs a few different people. Each testing method finds different problems, so a test plan combines all three:

How Can HealthTech Teams Turn Inclusive Design Into a Product Advantage?

HealthTech teams turn inclusive design into a product advantage by funding two layers from discovery: legal compliance and everyday usability. The legal layer, WCAG 2.2 AA and the dated EU and US rules, sets the minimum every product needs. The usability layer covers plain language, short flows, language coverage, and testing with older adults, and it shapes how easily patients finish tasks such as refills and bookings.

Monterail designs and builds health products with compliance built into the whole development lifecycle, as in its six-year partnership with Eargo across three FDA-cleared device generations. Talk to our HealthTech experts about building accessibility in from discovery.
