Garmin smartwatch data integrated into women's metabolic health platform Hello Inside
Collaboration enables personalised, longitudinal monitoring for women throughout hormonal transitions
Smartwatch data from wearables company Garmin is being integrated into the women’s metabolic health platform Hello Inside, as the company looks to deepen personalised insights into how lifestyle factors such as sleep, stress, exercise and diet affect glucose stability and hormonal health.
Hello Inside is an AI-powered digital health platform focused on women’s metabolic health, using continuous glucose monitoring (CGM), self-reported data and wearable biometrics to generate real-time, personalised insights. The integration incorporates data from selected Garmin smartwatches, including sleep metrics, heart rate variability (HRV), activity tracking and stress indicators.
According to Hello Inside, the combined data is used to help users understand how daily behaviours influence metabolic health across hormonal transitions, including menstrual cycles, pregnancy, perimenopause and menopause.
“The integration of wearable biosensors with continuous glucose monitoring is enabling the personalised, longitudinal monitoring women need throughout their hormonal transitions,” said Mario Aichlseder, CEO and co-founder of Hello Inside.
“Our collaboration with Garmin is powerful because of the precision data they deliver. Their advanced sleep features, HRV monitoring and biometric tracking give us the accuracy we need to decode metabolism in real-time.”
Garmin devices supply additional biometric inputs that are layered with glucose data within the Hello Inside platform to provide a broader picture of health and wellness.
Hello Inside said clinical data from its platform shows users achieve an average weight loss of 4 kg over three months through metabolic optimisation approaches, rather than calorie restriction, with 76% reporting overall symptom improvement.
Using sleep, stress and cycle data
Sleep data from Garmin devices is used to examine the relationship between restorative sleep — including REM and deep sleep — and glucose stability. Hello Inside overlays sleep metrics with CGM data to show how poor sleep may affect next-day blood sugar patterns, particularly during hormonally driven periods of sleep disruption such as PMS, pregnancy and menopause.
Stress-related biometric data, including HRV and Garmin’s stress tracking and Body Battery™ metrics, is combined with glucose readings to analyse cortisol-related glucose responses. When physiological stress indicators are detected, the platform can prompt mindfulness or recovery recommendations, while visualisations show how stress correlates with glucose fluctuations throughout the day.
The platform also uses Garmin’s Women’s Health API to factor in menstrual cycle phase, length and variability. Hello Inside applies this information to adjust guidance around exercise intensity, nutrition and recovery, reflecting known changes in insulin sensitivity across the menstrual cycle.
Workout data synced from Garmin devices is analysed alongside glucose responses to assess how different exercise intensities affect metabolic outcomes at various points in the cycle. For example, the platform may highlight differing glucose responses to high-intensity exercise during follicular versus luteal phases.
Hello Inside positions the integration as part of a broader move toward preventative, long-term metabolic monitoring in women’s health, combining wearable data, glucose tracking and AI-driven analysis to support metabolic health across the lifespan.
“When you combine comprehensive smartwatch data with continuous glucose monitoring and AI, you get a system designed specifically around women’s physiology,” said Aichlseder.
