Hello Inside explicitly invites users to explore how nutrition, stress, sleep, movement and hormones affect their metabolic responses—day by day, cycle by cycle. The app includes cycle-specific symptom tracking, allowing menstruating users to observe how hormonal phases influence glucose levels. This is a meaningful and often-overlooked feature in general health tech tools, where the female hormonal cycle is either ignored or treated as a confounding variable.By enabling users to correlate subjective symptoms with real-time physiological data, Hello Inside helps bridge an important gap: the lack of actionable, sex-specific feedback in mainstream health tracking tools. The app includes educational program content on perimenopause and menopause; an often over-looked life stage and variable in health tech. While not a medical device, the app offers a strong step toward more equitable, data-driven preventive care.

Hello Inside meaningfully supports gender-aware interpretation of metabolic data. The app places continuous glucose measurements in the context of a user’s menstrual cycle, nutrition, stress levels, sleep, and physical activity, allowing individuals—particularly women—to understand how hormonal fluctuations and lifestyle choices influence their glucose response. Rather than applying a uniform threshold or rule, Hello Inside promotes self-experimentation and insight-building. This approach supports the development of personalized patterns that are more reflective of female physiology, which is often underrepresented in both medical research and digital health design. By encouraging users to track and interpret their data through a gendered lens, Hello Inside helps close the gap in how biological sex differences are considered in preventive health.

Hello Inside lowers the barrier to understanding complex metabolic data by focusing on core usability principles. The app applies best practices in interface design to ensure that users—regardless of their medical or technical background—can easily navigate, understand, and act on their health information. Key usability strengths include:

• •A clean and intuitive layout that minimizes cognitive load
• •Consistent feedback and guidance during onboarding and daily use
• •Use of visual explanations to translate raw data into understandable trends



Clear language and supportive prompts that follow principles of recognition over recall Hello Inside demonstrates a high degree of usability in line with well-established design heuristics. This approach ensures that a wide range of users can meaningfully engage with their metabolic data and make informed choices—without needing expert knowledge.
