Health Nudge — Check-Up Reminder Assistant

A lightweight workflow to help people stay on top of routine health check-ups — sequencing reminders around how people actually forget appointments, not just firing on a fixed calendar cadence.

The problem

Calendar reminders assume forgetting is about timing — it's usually about friction

A fixed reminder fired once a year rarely lands at a moment someone can actually act on it. People don't skip check-ups because they don't care — they skip them because the reminder showed up at the wrong moment and there was no easy next step attached to it.

Solution

Health Nudge: reminders that adapt, and a snooze that doesn't mean "never"

SEQUENCED

Reminders that escalate, not repeat

Instead of firing the same notification on a fixed cadence, reminders sequence around whether a person has engaged yet — so month three doesn't sound identical to week one.

LOW FRICTION

Confirm or snooze in one tap

Every reminder carries an immediate next step — confirm it's booked, or snooze to a moment that actually works — instead of just a due-date notice.

CLOSED LOOP

Marked done means actually done

Completed check-ups are tracked so the next reminder resets from the real last visit, not from when the app assumes one happened.

Prototype

A working app, not just a flow diagram

Health Nudge is built and live — sequenced reminders, confirm/snooze and completion tracking all work end to end in the prototype below.

Process

Started from why reminders get ignored, not just that they exist

Discovery
Problem discovery — used Claude to pressure-test why fixed-cadence reminders get dismissed, before designing the sequencing.
Flow
Reminder-flow design — mapped the escalation, confirm/snooze and completion loop so every nudge carries an actionable next step.
Prompts
Prompt engineering — wrote the prompts that adapt reminder tone and timing based on prior engagement.
Build
Prototype — shipped a working, clickable app on Lovable rather than leaving the concept as a deck.
