◆◆メディア掲載◆◆ 2026.07.02 更年期障害予防アプリ(WellAge)がTBS news23で紹介されました。 2025.10.26 更年期障害予防アプリ(WellAge)が産経新聞に掲載されました。 本アプリケーションは、ウェアラブルデバイスおよびAppleヘルスケア連携を活用し、日常生活における生体情報をモニタリングすることで、自律神経のバランスを整え、更年期障害の予防・対策を支援することを目的としています。 ◆ 主な特徴 ◆ Apple Watch、Oura Ring などのウェアラブルデバイスとAppleヘルスケアを連携し、心拍変動(HRV)、心拍数、歩数、活動量、VO₂ Max、睡眠時間などの生体データをアプリで一元管理します。これらにメンタルヘルスおよび更年期に関する質問票を組み合わせ、更年期症状を総合的にスコア化し、フィードバックを行います。 ウェアラブルデバイスを使用しない場合でも、質問票機能をご利用いただけます。 ▼ 総合スコア機能 更年期症状、不安・抑うつ症状、睡眠、活動量、心拍変動などの指標をもとに、状態を総合スコアとして可視化します。表示されるアドバイスを参考に体調管理を行えます。 ▼ バイタル機能 Appleヘルスケアと連携することで、HRV、安静時心拍数、呼吸数、皮膚温度、血中酸素飽和度(SpO₂)、睡眠データなどをモニタリングできます。 Apple Watch や Oura Ring など、Appleヘルスケアに対応したウェアラブルデバイスをご利用いただけます。 ※連携にはAppleヘルスケアとの接続許可が必要です。 ◆ 学術研究 ◆ 順天堂大学大学院医学研究科では、更年期障害と心拍変動などの生体情報に関する研究を進めています。男性更年期に関する患者データを多角的に解析し、重症度との関連を検討してきました。 研究成果は 2025 Biomarkers of Aging Conference(米国ボストン)などで発表されています。現在は、性差を考慮した予防・治療戦略につながるウェアラブルシステムの社会実装を目指しています。 ◆ おすすめの方 ◆ 更年期症状が気になる方、ストレスを感じやすい方、健やかな生活を送りたい方におすすめです。必要なときだけの利用も可能です。 本アプリは、令和5年度セコム科学技術振興財団 特定領域研究助成 「ジェンダード・ヘルスサイエンス研究領域の創出による多様な人々の健康向上」 の研究事業として開発されました。 研究代表者 順天堂大学大学院医学研究科 泌尿器外科 特任教授 井手 久満 アプリ企画・開発統括 順天堂大学大学院医学研究科 創造長寿医学講座 客員准教授 駒澤 真人 This application supports autonomic nervous system regulation and the prevention of menopausal disorders by monitoring daily physiological data through wearable devices integrated with Apple Health. ◆ Key Features ◆ The app integrates physiological data such as heart rate variability (HRV), heart rate, step count, physical activity, VO₂ max, and sleep duration through Apple Health connectivity using wearable devices such as Apple Watch and Oura Ring. These data are combined with mental health and menopause-related questionnaires to generate a comprehensive symptom score and provide personalized feedback. The questionnaire functions are also available without wearable devices. ▼ Comprehensive Score The app visualizes an overall health score based on menopausal symptoms, anxiety and depressive symptoms, sleep, activity level, and HRV, supporting daily self-care through guidance comments. ▼ Vital Signs Monitoring By connecting with Apple Health, users can monitor HRV, resting heart rate, respiratory rate, skin temperature, blood oxygen saturation (SpO₂), and sleep-related data. The app supports Apple Health–compatible wearable devices, including Apple Watch and Oura Ring. Note: Permission to access Apple Health data is required. ◆ Academic Research ◆ At the Graduate School of Medicine, Juntendo University, research is conducted on menopausal disorders and physiological biomarkers such as HRV. Male menopause–related patient data have been analyzed to clarify associations with symptom severity. These findings have been presented at international conferences, including the 2025 Biomarkers of Aging Conference in Boston, USA. The research team is working toward the social implementation of wearable systems to advance prevention and treatment strategies that consider sex differences. ◆ Recommended For ◆ This app is recommended for individuals experiencing menopausal symptoms, those under stress, and anyone aiming for a healthy lifestyle. It can be used casually, only when needed. This application was developed as part of the FY2023 SECOM Science and Technology Foundation Special Research Grant, “Improving Health for Diverse Populations through the Creation of a Gendered Health Science Research Domain.” Principal Investigator Graduate School of Medicine, Juntendo University Department of Urology Specially Appointed Professor Hisamitsu Ide App Planning & Development Director Graduate School of Medicine, Juntendo University Department of Innovative Longevity Visiting Associate Professor Makoto Komazawa

Verdict
The clearest difference is in-app purchases: WellAge at none against Caloboo's 2. WellAge also leads on ads (none vs shown). Caloboo's advantage is update cadence (daily vs every 2 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
