The product question

How can care feel less clinical and more doable?

01Instructions live everywhere

Labels, bathroom shelves, alarms, and memory compete for attention.

02More tracking can create pressure

The experience needed to encourage consistency without turning a missed day into failure.

03Health-adjacent products need restraint

Skinny organizes existing instructions. It never diagnoses, recommends doses, or advises on missed medication.

Experience model

One timeline.
Four kinds of care.

Filter the reconstructed routine to see how different care categories keep their meaning while sharing one predictable interaction.

Interactive reconstruction from the shipped SwiftUI views and seed data. No stock photography or invented screen captures.

Product system

Useful every day.
Quiet when it should be.

Four connected surfaces support the full loop from planning to reflection.

☼

Today

A chronological plan, one-tap completion, ten-minute snooze, and medicine refill awareness. The next action stays obvious.

☷

Routines

Reusable morning and evening skincare sequences sit beside a complete care library with ordering and edit controls.

◔

Progress

Seven-day consistency and category filters reveal patterns without grading the person. A missed day is information, not failure.

◉

Discreet reminders

Notification text hides care names by default. People can opt in to named previews, and failed updates fall back to the private setting.

Trust architecture

Local by design.
Clear by language.

Care data and check-ins live on the device with SwiftData. The product makes its limits visible where they matter, not only in legal copy.

Private by default
Local storage, discreet notifications, no advertising SDKs.
Medicine stays essential
Reminders, dose logging, and refill fields remain free.
No false clinical authority
No diagnosis, interaction checking, dosing, or missed-dose advice.
Choice 01Timeline before dashboard

People arrive to act, so today’s sequence appears before analytics or configuration.

Choice 02Calm over gamified

Completion feedback is warm and tactile, without streak anxiety or punitive red states.

Choice 03Free medicine core

Paid depth can support the business, but essential medication behavior is not held behind Plus.

Build evidence

Designed as a product.
Built as a system.

The native prototype connects the product decisions to working data, scheduling, notifications, privacy behavior, and domain checks.
