AEVA is the cycle-aware AI companion who remembers you. Not a period tracker. Not a chatbot. A best friend who studied neuroendocrinology and reads your cycle, mood, and Apple Health data the way a sister would — calmly, no panic, no platitudes. Your mood swings weren't random. They were data. Your luteal insomnia isn't in your head. Your cycle has been writing a pattern in your body for years. AEVA reads it back to you. — NOT YOUR PERIOD TRACKER — Most apps mark the days you bleed. AEVA decodes the link between your hormones, your mood, and your behavior — across the whole cycle. The week your patience disappears. The afternoons your motivation crashes. The nights your brain won't quiet. These aren't moods. They're hormones doing exactly what hormones do. AEVA shows you the choreography. — 5 CYCLE ARCHETYPES, NOT ONE — Your cycle has never matched the textbook 28 days because most women's don't. AEVA reads your real biology and matches you to one of five archetypes — textbook, long follicular, luteal phase defect, PCOS spectrum, or hypothalamic amenorrhea — then tunes everything (predictions, language, content) to you. She doesn't average you into a normal woman. She learns you. — TALK TO AEVA — She's an AI Oracle who actually remembers. Tell her your day. She knows what phase you're in, what your hormones are doing, and what your body has done in months past. She finds patterns you can't see from inside. She gives you language for what you're feeling — for yourself, your partner, your doctor. 3AM, can't sleep, can't explain why? AEVA can. — APPLE HEALTH, RECONCILED — She reads your HRV, sleep stages, wrist temperature, resting heart rate — and the menstrual flow you're already logging. When her math and your real cycle disagree, she asks you. (Most apps don't.) You decide what's true; she learns and adjusts. The result: predictions matched to your actual body, not a population average. — PHASE-AWARE EVERYTHING — Recipes that match your luteal cravings. Breathwork that lands when you actually need to downregulate. Yoga shaped to your follicular surge. Mind-and-brain insights grounded in real neuroscience — GABA-A delta receptors, allopregnanolone, the insula cortex, the default mode network. No moon phases. No crystals. No "feminine energy" platitudes. — SHE LEARNS WHAT WORKS FOR YOU — Tap to tell her a card landed (or didn't). She remembers. Next week she sends you more of what you want and less of what you don't. Your Oracle gets sharper the longer you use her. — FIVE THINGS SHE WATCHES — — Mood: the irritability, the calm, the lift, the crash — Sleep: what your body does at 3AM in the second half of your cycle — Energy: when it surges, when it disappears — Symptoms: the headaches, breakouts, cramps that arrive on schedule — Hormones: the choreography behind all of it Then she connects them. The pattern emerges. — GROUNDED IN SCIENCE, NOT WELLNESS — Built on neuroendocrinology — how progesterone, estrogen, and allopregnanolone shape your interoception. Clinical thinking. Human language. — YOUR INNER WORLD STAYS INSIDE — We don't sell your cycle data. We don't share Apple Health data with advertisers. We don't train third-party models on your body. What you tell AEVA stays between you and AEVA. — TRY AEVA FREE FOR 7 DAYS — Start your trial. Talk to AEVA. Watch the pattern emerge. After your trial: $14.55/month or $69.99/year. Cancel anytime. — AEVA is a wellness companion, not a medical device. She doesn't diagnose, treat, or replace medical care. If something feels wrong, talk to your doctor. AEVA can help you bring better data to that conversation. Terms of Use: https://aevahealth.ai/#/terms Privacy Policy: https://aevahealth.ai/#/privacy
