Tools & Technologies
Key Features
Normalises payloads from Apple HealthKit, Google Fit, and Garmin into unified daily charts.
Instant camera scanning and AI food recognition with sub-second nutritional breakdown.
Dynamic interactive charts visualizing sleep cycles, heart rate variability, and workout intensity.
App Screens
Dashboard
Every key metric — calories, macros, steps, sleep — visible at a glance. Charts update in real-time from wearable integrations and manual logs, giving users a complete picture of their health.
Nutrition
Log meals by barcode scan, voice input, or text search. The AI-powered suggestion engine learns from user habits and pre-fills common meals, cutting logging time from 3 minutes to under 20 seconds.
Problems & How We Solved Them
Inconsistent wearable API data formats across devices
Built a normalisation layer that maps HealthKit, Google Fit, and Garmin payloads to a single internal schema. Added a validation step with user-friendly error messages when sensors report anomalous values.
