Case study 04 — Self-directed concept


A reminder that works when the user doesn't.

A medicine reminder for people who forget, and for the people who look after them: a caregiver can run the schedule for someone who cannot use the app.

The problem

01 — Two failure modes


The users who most need a reminder app are the least served by one.

  • Every product in the category assumes a person who can learn a new interface.
  • The people who forget most are often the ones who cannot.

Research

02 — Interviews


One-on-one interviews, four consistent signals.

  • Medication and appointments in one place
  • Simple to use — complexity is a dealbreaker, not a feature
  • Well-regarded clinics and pharmacies nearby
  • Someone else's schedule, not just their own

Personas built from the interviews

JennyEngineer, 31, two children

Runs the whole family's medicine; loses track of whose schedule is whose.

AurtherRetired, 63

Forgets doses through the day, finds modern apps unusable, and does not want to be a burden.

Architecture

03 — Before pixels


Kept deliberately shallow: every core task two taps from the bottom bar.

The product

04 — Four tabs


Four tabs, one job each. No nested menus.

Home: It's time for your medicine. Five medicine cards, each with dose time, days, stock left and an on/off toggle; one is paused and two show Left: 4, Refill needed, in red
Home — one card per medicine, one toggle each
Appointments: Don't be late for your appointments. Cards with date, time, the doctor and the clinic's number
Appointments — date, time, one-tap call
Parental: Take care of your loved ones. A grid of six people; Chandler's card carries a small red reminder
Parental — the people you look after
Nearby: a map of hospitals, clinics and pharmacies with filter chips for each
Nearby — well-rated clinics and pharmacies
Motion — swipe to delete; add it back in one sheet.

The caregiver

05 — The parental feature


The most important flow runs when the primary user does nothing.

  • The people you look after, in one grid; a card flags who needs a push.
  • Tap in for their medicine and appointments, and change them for them.
Motion — open Jamie, switch a medicine back on, check the appointments.
Jamie's medicines as the caregiver sees them: five cards with times, days and dark toggles; one paused, two showing Left: 4, Refill needed
Jamie's appointments, the second tab of the same screen: dated cards with the doctor and the clinic's number

Up close

06 — Four decisions


Choices that served both personas at once.

A — Stock

Inventory that warns early

The counter turns red well before zero, so nobody is caught out mid-course.

A medicine card: Amifostine at 09:42 PM, Monday to Thursday, with Left: 4 and Refill needed in red under the name

B — Toggle

One toggle per medicine

A whole schedule is one tap — no forms, no dialogs to get lost in. Removing one is a swipe.

The same card swiped left, revealing a red Delete action with a bin icon beside its toggle

C — Schedule

The whole schedule on one sheet

Time, days and duration together, with oversized numerals and generous targets.

Set your alarm sheet: an hour and minute wheel with AM and PM, day chips from S to S, a duration dropdown, and Cancel and Save

D — Pairing

Pairing by QR, not setup

One scan from the caregiver; the other person configures nothing.

The invite code: a QR code on a white card over Remedi's teal gradient

The system

07 — Components


Soft surfaces, one teal, and a component for every repeated part.

  • Montserrat throughout; large numerals for times and doses.
  • Neumorphic cards and controls on a pale mist ground, gentle on purpose for a product that sits next to health anxiety.
  • Teal #04BFBF · primary
  • Teal gradient · headers
  • Navy #092C37 · text, caregiver
  • Mist #F3FBFE · ground
  • Red #F82F22 · refill, delete
Card components: medicine cards on, paused and warning, appointment cards, an expanded illness card, edit and delete actions, contact rows and people chips
Cards and their states

Tab bar, every state

Trade-offs

09 — Four calls


Four calls, and what each one cost.

01

A toggle, not a form

GainedA whole schedule on or off in one tap.

CostAny detail change goes through the edit sheet.

02

The caregiver can edit

GainedIt works for someone who cannot use the app.

CostConsent between two accounts has to be designed: the access code.

03

Pairing by QR

GainedNothing to set up for the older user.

CostPairing needs the phone in hand, or the code.

04

Soft, low-contrast surfaces

GainedCalm, for a product next to health anxiety.

CostField and card edges are faint for older eyes.

Outcome

10 — What it left behind


A tested prototype, and one flow worth taking further.

  • End-to-end in 4 weeks: interviews, architecture, UI, and a prototype tested with users.
  • A concept, not a shipped product: no usage figures exist, so none are claimed.

What I’d do differently

ContrastRaise contrast on fields and cards, and test at arm's length with older users.

Missed doseDesign the escalation end to end: when the caregiver hears, and how.

MeasureTest adherence over weeks, not in a single session.

I designed this for my grandmother

11 — Why it's personal


The parental feature exists because of my grandmother, who cannot use a smartphone at all. My sister or I handle her reminders remotely. The most important flow in this product is the one that runs when the primary user does nothing — because for some users, doing nothing is the default.
