Tagline: Hormonal care made easy — sync your cycle, fuel your mind. Document owner: Product (Lucia Cebrian, COO) Status: Built · Phase 1 beta · Live web app + native apps sharing one backend (July 2026)
Healthcare and mainstream nutrition were designed around male biology. Men run on a roughly 24-hour hormonal cycle; women run on a roughly 28-day cycle with four distinct phases (menstrual, follicular, ovulatory, luteal). "One-size-fits-all" diet and training advice ignores this, leaving women to self-experiment with food and movement across phases — with the cost showing up as later diagnoses, worse outcomes, and everyday frustration.
The opportunity: the FemTech market is projected to grow from roughly US$10B (2018) toward roughly US$70B by 2030 (Grand View Research). Existing apps (Flo, Clue, 28, Flo Living) lead on period tracking but only partially cover science-backed cycle-synced nutrition, integrated movement, personalization, and clinician-partnered distribution. That gap is NutriSync's wedge — and, crucially, we now have a working product occupying it rather than a pitch deck describing one.
A cycle-synced nutrition and movement intelligence companion that adapts daily food, training, and wellbeing guidance to where a woman is in her cycle — grounded in clinical evidence, personalized to her own logged data, and backed by community. The product's core intellectual property is the CAS (Cycle Alignment Score): a single, explainable 0–100 number that tells a user how well her day aligned with her current phase, and recomputes in real time as she logs.
Primary persona — "Olivia," 25–45, cycle-aware self-optimizer. She already tracks her period, exercises, and cares about nutrition, and she is tired of generic advice. She wants to know what to eat and how to move today, given her current phase, without doing the research herself.
Secondary personas: - Women with cycle-related symptoms (PMS, low energy, bloating) seeking relief through nutrition and movement. - B2B end-users: female employees reached through employer wellness programs (€35–€50 per employee/year is the B2B unit).
Validation to date: 120+ interviews, an early cohort of 100 women (96% cycle-aware, 86% engaged), and 13K+ content views. The current phase moves validation from interviews toward in-product behaviour, with the beta instrumented to observe real logging and CAS engagement.
The product is built, so success metrics now frame the beta: are real users logging, and does the CAS keep them coming back? These are the north-star signals we watch during the Madrid tester cohort and early beta.
| Goal | Metric | Beta target |
|---|---|---|
| Daily relevance | D7 / D30 retention | D7 ≥ 40%, D30 ≥ 20% |
| Habit formation | Logging streak (meals / symptoms / movement) | ≥ 3 days/week median |
| Engagement | WAU / MAU | ≥ 45% |
| CAS engagement | Users who see their score move after logging | majority of active users each session |
| Monetization signal | Free → premium intent | ≥ 10% (deck assumption, to be validated) |
North-star metric: weekly active women completing ≥1 phase-aligned action (logged a recommended meal, completed a movement item, or read phase guidance) — the action that both drives the CAS and signals real habit.
The app is now effectively 1:1 with the Figma prototype. Every screen below is built, functional on live data, and wired to the Supabase backend and the CAS engine. The same backend powers both the native mobile apps and the live web application, so a user's cycle, logs, and score are identical wherever she signs in.
Welcome → Auth (sign up / sign in) → a multi-step Wizard that captures cycle data (including the critical last period start date), health, nutrition preferences, NutriGoal, Nutri avatar, city, and consent. Answers persist to users and cycles, so every downstream recommendation is filtered to the individual from the first session.
A "Before we Sync" mood/energy gate that appears once per calendar day on first open, feeding the CAS biomarker and logging components.
Real Figma emotes, flow droplets, and symptom logging (mood-state, pain, digestion, cravings, sleep, energy, and more) writing to daily_logs and feeding biomarkers.
A NutriGoal carousel (locked until two full cycles are completed), Allergies chips, and Health Conditions chips, writing to users.nutrigoal / allergies / health_conditions.
A live feed computed from real cycle, phase, and logging state — phase tip, check-in nudge, today's score, and milestones — reached via the 🔔 on the home header. Nothing here is canned; it reflects the user's actual state.
A Settings hub plus Personal Information, Sign-in & Security, Data Privacy (JSON export + delete account), Community Privacy, Notifications & Reminders, Choose Your Nutri, App Preferences (units, week-start, haptics, appearance — saved on-device), and Nutritional Preferences (diet type + allergies, written to users).
The official Figma NutriBubble orb appears throughout, alongside an animated "looking-around" branded loading screen and real Figma emotes. Poppins is the app-wide typeface; brand orange is #FF5509 with an orb gradient #FF9269 → #FF5509.
Intentionally deferred (known non-Figma gaps): wearable connectors (native-only, roadmap 2028) and 2FA / passkeys.
Guidance adapts to the user's menstrual phase, and phase boundaries personalize from her own logged cycle data rather than a fixed 28-day assumption. Under the hood the CAS uses five internal phases (menstrual, follicular, ovulatory, early_luteal, late_luteal); the user sees four display phases.
| Display phase | Approx. days | Colour | Nutrition focus | Movement focus |
|---|---|---|---|---|
| Menstrual | 1–5 | #E8472A |
Iron, warming foods, hydration | Gentle movement, rest |
| Follicular | 6–13 | #6B9E6B |
Fresh/light, complex carbs, protein | Build intensity, strength |
| Ovulatory | 14–16 | #D4A017 |
Anti-inflammatory, fiber | Peak performance, HIIT |
| Luteal | 17–28 | #7B5EA7 |
Magnesium, complex carbs, mood support | Steady-state, deload late |
The phase is derived as cycleDay = today − last_period_start + 1, wrapped to cycle length. Everything on Home, NutriLog, Movement Log, and the Notification Center keys off this. Content is reviewed by the clinical advisor (Constanza Ramirez Milli) and evidence-tagged before publish.
