Rhythm Cycle Tracking

Rhythm helps you understand your emotional patterns — and share that understanding with the people who love you. Most cycle apps track dates and symptoms. Rhythm goes deeper. Every day, your AI companion reads your notes and your cycle phase to reveal the emotional patterns beneath — the tendencies, the sensitivities, the strengths that repeat across your cycles. Not a symptom log. A mirror. FOR YOU Log a note about how you're feeling — it takes 30 seconds. Rhythm's AI weaves it into a personalized daily insight grounded in where you are in your cycle and what you've written before. Over time, you start to see yourself more clearly: what you personally need in your different phases, and how to take amazing care of yourself through it all. FOR YOUR PARTNER Rhythm can share a thoughtful, AI-crafted daily update with your partner — translated from your experience into something they can act on. They don't need to ask how you're doing. They just know. It's not about oversharing. It's about being understood without having to explain everything. TWO MODES Cycle Tracking — full menstrual cycle tracking with phase predictions, daily AI insights, and optional partner sharing. Wellness Journal — daily journaling and AI insights without cycle data, for anyone who wants emotional pattern awareness without period tracking. PRIVATE BY DESIGN Your notes and AI conversations are encrypted. Your emotional life stays yours. Rhythm is not a medical service and does not provide medical advice, diagnosis, or treatment. Its insights are for reflection, based on what you log. For any health concern, or before making a decision about your care, please talk with a healthcare professional. Free to use — start today.
