Designing an inclusive mobile experience for users with low digital literacy required rethinking the entire interaction model — from navigation to data input to how we communicate progress. The result launched to a 4.8★ App Store rating.
Our client — a non-profit focused on preventive health in under-resourced communities — had an existing mobile app with a 2.1★ rating and 73% churn in the first week. Users were abandoning it not because they didn't care about their health, but because the app assumed skills and confidence they didn't have.
This wasn't a problem with user motivation. It was a failure of design to meet people where they were.
"How might we design a health tracking experience that feels approachable and trustworthy for users with low digital literacy — without making them feel talked down to?"
The research phase was the most demanding of my career. We conducted 18 contextual interviews with users in their homes and community centers — not in a sterile UX lab. We observed people using smartphones, watched them navigate the existing app, and asked about the last time technology had frustrated them.
Immediate understanding without reading. Confirmation that they did things "right." Privacy — they didn't want family members to see their health data. Forgiveness — the ability to undo or correct without fear.
Dense text-heavy instructions. Jargon (e.g., "BMI", "systolic"). Overwhelming dashboard with 12+ metrics. No feedback when an action succeeded. Punishing error states with no clear recovery path.
We also ran a plain language audit of the existing app: every string of copy was graded for reading level. The average was Grade 11. Our target was Grade 5–6.
The redesign was structured around five inclusive design principles that emerged directly from research:
We ran 6 rounds of usability testing with 5 users each, iterating between every round. The final prototype was tested with 12 users before handoff — all of whom completed core tasks without assistance.
The redesigned app launched six months after kickoff. App Store reviews cited "easy to understand," "doesn't make me feel stupid," and "I actually use it every day" as recurring themes — language lifted almost verbatim from our research insights.
The project was featured in a case study by the non-profit's health equity program and cited as a model for inclusive design in public health technology.
Lessons learned: Inclusive design isn't about dumbing things down — it's about removing unnecessary complexity that never served anyone in the first place. The redesign made the app better for all users, not just the ones we were designing for explicitly.
