Product Designer for Health, Fitness & Family AppsCalm digital products for people making decisions under pressure.
I design and ship iOS apps in health, fitness and family life — from problem framing and UX structure through interaction design, copy, prototyping and App Store release.
UX for real-life constraints
Parents with one free hand. Athletes mid-session. People who need the next useful action, not another dashboard.
Evidence-aware, not fear-led
My exercise-science background helps me design health-adjacent products with clear scope, calm language and honest uncertainty.
Designer who can ship
I use code and AI-assisted development to prototype, test and release the design — not just hand off static screens.
Three shipped apps, one product lens
Each app started with the same question: what does this person need to understand or do in the moment they actually use the product?
BabyEats
The week-by-week weaning planner
A calm, age-aware roadmap for first foods, allergen introduction and reaction tracking. Built for parents who want the plan, not another Google rabbit hole.
Timer | Interval
Interval timer that gets out of the way
HIIT, Tabata, EMOM, HYROX, boxing — 17 ready-made timers plus a custom builder. Big animated countdown, voice cues, haptics, landscape mode.
Leap Journey: Baby Activities
Leaps, milestones & play
Track baby leaps, milestones, mood and routines; get calm, age-aware insights and one gentle activity to try today.
Product thinking before pixels
My strongest work sits where UX, behaviour change and practical shipping meet. I like messy domains where the product has to reduce uncertainty without pretending life is simpler than it is.
Frame
Define the user, moment of use, constraint and job-to-be-done before designing screens.
Structure
Turn complexity into flows, information architecture and progressive disclosure.
Prototype
Use code, copy and realistic data early so interaction decisions are tested, not imagined.
Ship & learn
Release, read feedback, tighten the experience and decide what deserves another iteration.
Ex-scientist. Product designer. Builder.
I trained as an exercise scientist — Bachelor of Exercise & Sports Science, then years working alongside physiotherapists, running rehab-informed strength programs and doing clinical exercise research. The academic side gave me a taste for reading the paper before believing the headline. The clinical side taught me that most people don't need more information — they need the right thing to do, right now.
Sometime in the last two years I started building the apps I kept wishing existed while coaching and parenting. A weaning planner that wasn't five forums duct-taped together. An interval timer that didn't upsell mid-workout. A leaps tracker that gave parents an actual next step instead of another chart.
So the portfolio you're on is what happened after: a product designer who came in through the health-science door, then learned enough code to ship and evaluate his own ideas. It shapes what I build. Every app here is educational, calm, honest about uncertainty, and designed to be usable by someone holding a baby or a kettlebell.
I still coach a handful of clients in Salou when the diary allows — entrenadorpersonalsalou.es.
Need a product designer who understands behaviour, health and shipping?
I'm open to product design roles, UX collaborations and founder-led projects — especially in health, fitness, family, behaviour change or tools for people under real-world pressure.
