Ritual:
emotional design
as a retention lever

Application for healthcare

When the family table
meets a diagnosis

Food is never just nutrition — it is memory, identity, and belonging. In a healthcare context, certain treatments impose drastic dietary requirements that disrupt the entire family dynamic, not just the patient. The methodology developed here translates directly into a high-stakes application: reducing caregiver mental load while preserving the emotional and social role of shared meals through illness.

The problem

Certain treatments — chemotherapy, renal disease, severe allergies — impose strict, shifting dietary rules
Family recipes become sources of anxiety rather than comfort
Caregivers carry the invisible mental load of rewriting every meal
Food rituals — the emotional glue of family life — are quietly lost
No existing tool bridges clinical dietary constraints with the lived family table

The product vision

A responsive app that generates adapted versions of the family's own recipes — using only clinically authorised ingredients
Sends family members a curated list of permitted ingredients with meal ideas, reducing daily decision fatigue
Preserves the ritual — grandmother's tart adapted, not abandoned
Reduces caregiver mental load at one of the most cognitively demanding moments of family life
Designed with — not for — families navigating treatment

The reframe

Not a question of novelty

Original board brief
"We want to improve retention and acquisition by understanding who can best appreciate on-going novelty."
Research-led reframe
"How can novelty and rituals cohabitate so that our app adapts to people's lives and improves them?"

"The novelty question is secondary. The real question is how can an app cater and make space for beloved food rituals."

Phase 1 — Foundational research & desk research

Game-changing
source of insight

An unconventional insight source made it possible to reframe the problem before even discussing the interface. Data analysis and desk research of when apps lose traction — and for whom — surfaced a family pattern: too much mental workload and logistics to keep up with novelty, combined with a deep desire to instil and pass on family food traditions.

01
Data analysis · App churn patterns
Desk research into retention data and category drop-off points. When do users disengage — and who disengages first?
Families with children churn fastest after initial novelty
Mental load of weekly meal planning incompatible with content-first apps
High intent, low follow-through — a behavioural gap, not a content gap
02
Desk research · Cultural & behavioural signals
Cross-referencing food sociology, family anthropology, and digital habit research to build a strategic hypothesis.
Food rituals are identity anchors — not consumption moments
Novelty and ritual operate on different emotional registers
Reframe hypothesis: the app must serve memory, not just discovery

Phase 2 — User Research

From anthropology
to diary study

An unconventional insight source made it possible to reframe the problem before even discussing the interface. Working with a recruitment provider specialised in ethnographic research, we recruited 12 participants — a nationally representative sample of French families, spanning age, household composition, and relationship to cooking.

01
Interview · Food Anthropologist
An unconventional source. Rather than a benchmark, we began by understanding the psychology of food rituals.
Food is a social ritual, not content
People seek meaningful repetition, not novelty
Reframe: emotional design problem, not content problem
02
12 user interviews
Open-ended questions on the emotional relationship to family cooking.
Universal fear of losing orally-transmitted recipes
Novelty creates anxiety, not pleasure
WhatsApp heavily used to share recipes
03
Diary study · 3 weeks
"Document your family recipes" — observation of real behaviours.
100% of participants have orally-transmitted recipes
Blurry WhatsApp photos · handwritten notebooks · no dedicated tool
Strong desire to materialise in physical form
M
Marie · 42 · Mother
She cooks her grandmother's recipes for Christmas and Easter. She shares them via blurry WhatsApp photos. She's afraid the recipes will disappear with the older generation. Her dream: to give her children a family recipe book that will last for generations.

"My mum sent me her tart recipe as a WhatsApp photo 3 years ago. She's since passed away. Being able to import it and print it in a recipe book... that's exactly what I needed."

Phase 4 — Design studio

An ecosystem
for family transmission

We invited participants to design their ideal features during a co-creation session — each paired with a UX/UI designer who translated lived experience directly into interface concepts. Not 4 isolated features — a coherent system where each component reinforces the others.

Phase 5 — Aligning product & business strategy

From customer truth
to market fit

Before committing to build, we validated the business case. Market sizing confirmed the addressable opportunity; ROI modelling stress-tested each feature against retention and revenue projections. The fit was clear — and the numbers backed it.

01
Business validation · ROI & market sizing
Cross-referencing customer insight with market data to confirm viability before a single line of code was written.
Market sizing confirmed significant unaddressed family segment
Retention modelling showed ritual features outperform novelty on LTV
Printed book identified as premium revenue stream with high emotional ROI
02
Technical alignment · Algorithmic workshop
A working session with the engineer responsible for the app's algorithmic model — bridging customer needs with existing technical architecture.
Seasonal reminder logic mapped to existing recommendation engine
WhatsApp import feasibility confirmed with minimal backend impact
Family tagging system integrated into current data model
03
UX/UI iteration · Concept testing
Updated interface concepts presented by the UX/UI team — tested first with the original participants, then with a larger nationally representative sample.
Original 12 participants validated concept fidelity to their expressed needs
Wider nat rep sample confirmed transferability beyond the core panel
Refined by A/B testing prior to launch — data-led final decisions

Phase 6 — Impact & business model

Growth was
in the ritual

Research doesn't end at insight. The final deliverable was a dual output: a strategic playbook to align teams, and a stakeholder-ready presentation anchored in business metrics.

"The brief was: reduce churn. The research led us to WhatsApp, handwritten notebooks and the fear of losing family memory. The solution wasn't in the app — it was in a behaviour users already had."
