As answered by people managing CalyxOS and Menoup.app.
Menoup.app's answer:
Menoup brings the different parts of perimenopause and menopause into one connected picture. Instead of tracking symptoms, sleep, cycle, nutrition, movement and hydration in separate apps, users can manage them all in one place. Mona, Menoup’s built-in AI, can use recent diary context to provide more relevant support and can even log updates directly from chat. Menoup also combines daily data into weekly Balance Scores, integrates with Apple Health and Health Connect, explains lab results in plain language, and creates doctor-ready 30- or 90-day health summaries.
Menoup.app's answer:
Menoup is designed for women who want more than a symptom tracker or a generic AI chatbot. It connects 35 menopause symptoms with sleep, cycle, nutrition, movement, hydration and health data so users can see patterns across their daily life. It also includes food, barcode and fridge scanning, lab result explanations, Apple Health and Health Connect integration, and customizable health summaries for medical appointments. The aim is to reduce the need for several separate health apps and provide one clear, connected view instead.
Menoup.app's answer:
Menoup is primarily designed for women aged 40 and over who are experiencing perimenopause, menopause or the transition into midlife. It is especially useful for women who want to understand changes in symptoms, sleep, cycle, nutrition, movement and overall wellbeing, keep their health information organised, and prepare more effectively for conversations with healthcare professionals. Menoup is available in nine European languages.
Menoup.app's answer:
Menoup started with a simple observation: during perimenopause and menopause, many areas of a woman’s life can change at the same time, yet the tools available to track them are often fragmented. Symptoms may be in one app, sleep in another, cycle data somewhere else, and nutrition or movement in yet another place. Menoup was created to bring those pieces together. The goal is to give women over 40 a calm, practical and connected way to understand their own patterns, supported by AI without replacing medical care.
Menoup.app's answer:
Menoup is built as a cross-platform mobile health application using React Native and Expo, with cloud-based backend services and secure data synchronisation. It uses AI models for conversational support, structured health insights, image-based food and fridge analysis, and plain-language explanations of lab results. Menoup also integrates with Apple Health and Android Health Connect to bring supported health and activity data into the user’s broader health picture.
Menoup.app's answer:
Menoup is a consumer health app designed for individual women rather than enterprise customers. We do not currently publish individual customer names.
