DoseCare is a medication management iOS app built around one core unmet need — confirmation. Designed from 9 user interviews and 129 research notes.
Older adults managing multiple daily medications face a problem that goes beyond scheduling. The challenge is often not remembering to take medication — it's remembering whether it was already taken. Existing reminder apps send alerts but offer no confirmation, no recovery from uncertainty, and no way to prove adherence.
Apps like Perx require complex manual prescription entry that many 65+ users cannot complete independently. This creates a reliance on family members at the very first step — before the product has delivered any value.
“How might we design a medication experience that helps older adults stay independent while making adherence more visible, understandable, and trustworthy?”
Semi-structured interviews with patients and caregivers, secondary research on the doctor perspective, and affinity mapping with tag-based synthesis. 129 notes were cleaned, tagged, and grouped into themes around uncertainty, overload, reminder fatigue, and weak support loops.
The core finding shifted the product direction: adherence is not a scheduling problem — it is a confidence problem.

Derived directly from research insights. Each design decision was evaluated against these principles.
Built directly from design decisions. Usability testing revealed where these assumptions broke down.
Task-based testing across three core flows: adding a medication, responding to a reminder, and finding medication information. The goal was to identify where users hesitated, what felt intuitive, and what needed clearer guidance.
Testing confirmed that the reminder confirmation flow was clear and satisfying — validating the confirmation-first model. It also exposed friction in onboarding and information discovery, reinforcing that clarity at entry points is as important as clarity in the core flow.
Patient app — 5 tabs. Refined after usability testing.
“DoseCare taught me that the best design for vulnerable users is not more features — it's relentless focus on a single core problem.”
