Tilda care app

Tilda is a mobile app that helps families coordinate the care of an ageing parent from a distance, replacing the tangle of paper notes and group chats with a single shared view of appointments, medication and tasks. It serves two very different users at once: a busy daughter managing care between meetings, and her elderly father who needs a simple, independent view of his own week. The concept stage now moves into flows and screens built around both realities from day one.

Overview & Goals

  • Give families one reliable place to track appointments, medication and who has done what, replacing scattered notes and chat threads.
  • Design a parent-facing view that works on its own terms: today and tomorrow, nothing hidden behind gestures or small type.
  • Make task handoff visible, so a daughter can delegate to another family member and see whether it happened, without chasing.
  • Onboard an older first-time user with confidence, not confusion, as the true test of the whole product.

Budget & Timeline

BudgetAround $30k
Timeline8 weeks to prototype

The first eight weeks are spent on flows and a clickable prototype, tested against the twenty family interviews already on file. The full screen set for the first build follows, targeted for delivery by the end of the quarter.

Stage
Concept, nothing built
Core flows
Add an appointment and see the week. Log that a medication was taken, by the parent or by anyone else. Hand a task to another family member and see whether it happened. A read-only view for the parent that shows today and tomorrow and nothing else. Onboarding for someone who has never been given an app by their daughter before.

Target Audience

Two people, two needs, one shared truth about a parent's week. The daughter needs speed and oversight on the move; her father needs clarity and independence at home.

Daughters and sons in their forties coordinating a parent's care remotely, checking in on the app between meetings and errands.Parents in their eighties who need a read-only, plain view of their own schedule, with no clutter and nothing hidden.

In the client's own words

Tilda is an app for people looking after an ageing parent from a distance. Appointments, medication, who called the doctor last, what the neighbour agreed to do on Thursday. It does not exist yet, there is no code and no design, only twenty interviews with people doing this today on paper and in a family chat group. The two of us have funded six months. What makes it hard is that two very different people use it: a daughter in her forties on a phone between meetings, and her father in his eighties who should be able to see his own week without being managed.

Scope & Deliverables

  • Figma screen designs for the full first release
  • Clickable prototype covering the core flows
  • Parent-facing read-only view, designed first
  • Onboarding flow for a first-time older user
  • Accessibility-compliant contrast and type sizing built in from the start
  • Offline-ready flows for logging medication and appointments

Do's & Don'ts

Do

  • Design the parent view first, it is the harder problem and it decides the rest.
  • Meet contrast and text size requirements as a starting point, not as a later pass.
  • Read the twenty interviews before drawing anything, they are the only real material this project has.

Don't

  • Do not design one interface and scale up the type for the older user, that is not the same thing.
  • Do not put anything behind a gesture that has no visible alternative.
