Conversational onboarding for a consumer health app
A health app where the intake interview is an AI conversation rather than a twelve-page form, with scoring built on connected platform data.

The problem
Consumer health apps lose most users in onboarding: the data needed to personalise anything is exactly the data nobody wants to type. The product also had to read from external health platforms under explicit consent, and derive a score users would trust from data of uneven quality — including users who simply have not got enough history yet.
What I did
Onboarding was split: a short structured form for the demographic facts, and a conversational intake for goals and preferences, with prompt assembly kept server-side so the model’s behaviour can change without shipping an app. Platform connection was built as a consent step rather than a permission dialog. Insufficient data is handled as a first-class state everywhere instead of a silent empty screen, and the API was migrated to a schema-first contract mid-project so mobile and backend stopped guessing at each other.
How it ran
- 01
Research and framing
Competitor review and user stories before build, to decide which of the intake questions actually earn their place.
- 02
Access and consent
Social and email sign-in with multi-factor, then health-platform connection handled as an informed consent step.
- 03
Intake
Structured demographic form plus conversational goal-setting, with baseline goals generated rather than asked for.
- 04
Scoring and insight
Activity scoring surfaced through a sector dashboard, with explanation on demand and an explicit state for insufficient data.
- 05
Contract and quality
Schema-first API migration, automated end-to-end mobile tests, and a managed test-case suite rather than manual scripts.

Multi-tenant iOS app for clinical staff, built offline-first because the corridors it runs in have no reliable connectivity.

One device, three roles, one signature
A paper handling process where a tablet passes from a ground agent to a flight captain and back. I prototyped the handover itself, because that is the moment the process either works or does not.
