Taking a women’s cycle-syncing app from concept to dual-platform launch

An AI-driven wellness app bringing daily guidance to the femtech landscape

About the project

Despite growing awareness around hormonal health, many women still navigate their cycle with little understanding of how it shapes their energy, mood, and daily capacity. The app at the center of this project set out to change that, helping women not just log their cycle, but live in sync with it. Created by a solo UK founder, it enters a market where most tools collect data but rarely help act on it.

Beyond tracking, the app brings together AI-driven daily insights, symptom logging, guided meditations, and a partner-sharing feature, covering physical and mental health in one space. Its calm, non-clinical design prioritizes emotional comfort over data density, making it feel more like a wellbeing space than a health tracker.

Challenge

The client came to us with a strong concept, zero existing product, and tight deadlines. The goal was to build a complete, marketplace-ready app, covering research, design and development, and faithfully execute a founder-defined vision for a calming, premium product that could stand out in a saturated femtech market.

Our process

In the femtech space, users share deeply personal health data and expect both accuracy and genuine care. That’s why, from a concept trial to a dual-marketplace launch, we shaped every layer of the product — UX, development, and quality — to match the brand’s emotional promise and earn the trust women place in it.

UX/UI design

Working from the client’s existing brand, our team guided design from competitor research through UX architecture and a screen library, creating a space that felt not just functional, but made for women.

Product development

We built the product’s foundation in React Native and Expo, structuring the architecture to handle complex cycle logic and real-time data with ease, so the app could scale without losing stability.

QA & release

Quality and compliance ran alongside development — systematic testing and early marketplace submissions kept the product on track for launch.

Our approach

The founder came to us with a clear philosophy: women’s health deserved more than a tracker. Our role was to translate that vision into a product, preserving its emotional intent across every layer of design and development.

01  ·  Research & concept exploration

We analyzed competing apps, mapping UX gaps and positioning opportunities in the hormonal health space. Two visual concepts emerged from the moodboard and trial sprint: one warm and photo-led, the other clean and icon-based.

Deliverables

  • Four competitors analyzed
  • Moodboard & references
  • Two design concepts

02  ·  UX architecture & key user flows

We designed flows for three user roles (main user, partner, visitor), covering onboarding, cycle logging, AI insights, partner management, and subscription states. Every interaction was shaped for minimal daily effort and quick access.

Deliverables

  • Three user role flows
  • Key screen wireframes
  • Subscription state logic

03  ·  UI design system & screen production

Building on the client’s brand guidelines, we developed a full design system: consistent tokens, components, and patterns across screens. A phase-progress arc on the dashboard echoes the logo form, tying brand identity to the core UI.

Deliverables

  • Full app screen UI
  • Design system & library

01  ·  Mobile app architecture & core functionality

We built the app in React Native and Expo, working in sprints across five modules: cycle calendar, daily logging, dashboard, physical health, and mental health. Weekly demos kept the scope aligned as the product grew beyond its original MVP.

Deliverables

  • React Native app build
  • Five core feature modules

02  ·  Cycle logic & AI integration

The cycle calendar was the app’s most complex challenge — every edge case was mapped and validated with the client before implementation. We then integrated an LLM for daily insights, adding Apple Health and Google Health Connect sync.

Deliverables

  • Cycle calculation engine
  • AI insights integration
  • Health platform sync

03  ·  Admin panel

Our team built a custom admin panel using AI-assisted scaffolding for the UI and a Supabase Realtime backend to handle multi-admin editing without conflicts. The client gained direct control over AI content, audio, tags, and user permissions.

Deliverables

  • Secure admin web panel
  • Multi-admin realtime sync
  • Content management system

01  ·  Multi-platform testing

We tested across iOS and Android on real devices and in emulators, covering functional, UX/UI, exploratory, offline and integration layers. Edge cases included AI health data, partner sharing across time zones, and Health platform integration.

Deliverables

  • Functional & exploratory testing
  • Health integration QA
  • Sync validation

02  ·  Compliance & marketplace launch

Submitting builds early during development let us absorb marketplace feedback before the final release. Android compliance for AI health apps required close attention — health data handling and AI functionality reviewed at each submission.
