Eldelia

Challenge

Designing for elderly users is one of the highest-stakes UX challenges: the audience is often unfamiliar with smartphones, easily overwhelmed by busy interfaces, and quick to abandon products that feel cold or mechanical. At the same time, Eldelia's core experience — AI conversation — is inherently abstract and difficult to make feel safe and human. The design had to make a genuinely advanced AI feel warm, predictable, and trustworthy to people who may never have used a chatbot before.

Solution

I designed the full product UI around one principle: reduce cognitive load at every step. Voice interaction is the primary input — no keyboard required — with large, high-contrast UI elements and a minimal screen layout that surfaces only what matters in the moment. The onboarding flow was built to be completed in under three minutes with no technical terminology. Conversation design prioritised warmth and patience: the AI responds at a calm, readable pace, and the interface never rushes the user. Medication reminders and shopping lists are accessible in one tap from the home screen, with confirmations designed to feel reassuring rather than transactional. The memory system — which allows the AI to recall previous conversations — is surfaced subtly so users feel recognised without feeling surveilled.

Outcome

Eldelia launched on both the App Store and Google Play and reached a 4.8/5 Trustpilot rating, with reviewers consistently citing ease of use and the feeling of genuine connection. The product demonstrates that AI can be made accessible and emotionally resonant for audiences that are typically underserved by technology design.
