A small daily check-in for perimenopause. Sulu helps you keep a simple record of how your symptoms change over time. No advice. No fixing. Just a clearer picture — one you can reflect on, or bring to your doctor. HOW IT WORKS A 30-second daily check-in. Rate the symptoms that matter to you, note what changed that day, and move on. Sulu does the rest. WHAT YOU CAN TRACK Pick 3–5 symptoms to focus on. Fewer makes patterns easier to spot. • Hot flashes & night sweats • Sleep disruption • Anxiety & overwhelm • Rage & irritability • Brain fog • Fatigue & low energy • Low mood & emotional swings • Menstrual changes • Heart palpitations • Joint & muscle pain • Headaches & migraines WEEKLY INSIGHTS After a few days of logging, Sulu shows you what changed week to week — which symptoms shifted, what stayed steady, and which factors showed up on harder days. No cause-and-effect claims. Just your data, clearly laid out. SYMPTOM DETAIL Tap any symptom to see a 30-day trend, data-driven insights, and which triggers correlate with better or worse days. DOCTOR EXPORT When you're ready, export a clean PDF summary to bring to your doctor. It covers your tracked symptoms, weekly trends, and daily factors — designed to support a conversation, not replace one. BUILT WITH CARE • Offline-first — your data syncs when you have signal • Private — your data stays yours • No medical claims — this is a personal record, not a diagnosis tool • Calm, warm design — because this stage of life deserves better than clinical dashboards This app does not diagnose, treat, or recommend changes. If anything feels worrying or persistent, a doctor is the right place to start. Mark daily factors like stress, exercise, alcohol, HRT, or supplements to see what tends to show up alongside stronger days.
