Custom AI-Powered Healthcare & Wellness App

United Kingdom

Project Brief

A visionary health-tech entrepreneur from United Kingdom approached us with the ambition to reshape how individuals manage their well-being — not just by tracking health data, but by delivering AI-driven, personalized coaching. The goal was to create a comprehensive mobile health application that could act as a personal wellness assistant, combining fitness tracking, nutritional insights, mental health monitoring, and menstrual health support — all powered by a conversational AI.

We developed an iOS-based AI health & wellness app featuring a smart AI coach named “Nova,” designed to offer real-time, personalized health advice. The platform integrates deeply with Apple HealthKit, supports offline capabilities, and offers a suite of tools for nutrition logging, cycle tracking, goal setting, and workout management. With visual insights, predictive health alerts, and adaptive guidance, the app empowers users to take control of their physical and mental wellness through an intelligent, all-in-one solution.

Client's Need

The client wanted to build a multi-functional iOS health app that went far beyond basic step-counting. They envisioned a platform where AI could coach users in real-time, answering questions, suggesting improvements, and tracking overall wellness.

They needed the app to combine nutrition, fitness, menstrual health, and goal tracking — offering one unified experience across all health domains.

The app had to integrate seamlessly with Apple HealthKit, support offline access, and ensure enterprise-grade data privacy for sensitive user health data.

The client also wanted to deliver a truly personalized experience, where the AI could adapt to each user's health data, preferences, and lifestyle to offer contextual advice and proactive suggestions.

Challenges

Designing a scalable, multi-domain health system that seamlessly integrates diverse modules like fitness, menstrual tracking, and nutrition.

Developing an AI coach (Nova) that delivers context-aware, real-time health insights while maintaining a conversational, user-friendly tone.

Ensuring offline-first architecture, where users can log data and access recommendations even without internet connectivity.

Building flexible goal-setting mechanics that support numerical, visual, timer-based, and checklist-based goals — and adapt based on progress.

Creating a user experience that’s both intuitive and comprehensive, accommodating everyone from fitness pros to health beginners.

Maintaining data privacy and HIPAA-level security for sensitive health metrics and AI-generated recommendations.

Solutions

We built an AI-powered conversational health coach, “Nova,” that uses NLP and contextual understanding to guide users across wellness domains — from nutrition to stress.

Developed a modular app architecture where each health module (nutrition, cycles, fitness, mental health) works independently yet shares data contextually across the system.

Integrated Apple HealthKit to import and sync critical metrics such as heart rate, steps, sleep, and menstrual cycles — feeding Nova with real-time inputs.

Designed a dynamic goal system that supports a variety of goal types (weight loss, performance, habit formation) and visualizes progress with smart analytics and streak tracking.

Implemented offline functionality, allowing users to interact with the app, log data, and even chat with Nova without an internet connection. Sync resumes automatically when back online.

Created a robust onboarding journey, collecting preferences, lifestyle, medical history, and goals to personalize recommendations from day one.
