WHO SOLACE IS FOR • Women in perimenopause wondering if what they feel is hormonal • Women in menopause or postmenopause tracking hot flashes, night sweats, sleep and mood • Anyone on HRT (hormone replacement therapy, or MHT) or a non-hormonal treatment who wants to see what changed after starting or adjusting it • Women with irregular periods or none, including after a hysterectomy (ovaries removed or not), surgical menopause or with a hormonal IUD. Without a cycle, Solace estimates your stage from symptoms • Anyone preparing for a doctor, gynecologist or menopause clinic appointment WHAT YOU CAN TRACK • A daily diary for 21 menopause symptoms, each mild, moderate or strong: hot flashes, night sweats, poor sleep, fatigue, mood swings, anxiety, irritability, brain fog, joint pain, headaches, palpitations, weight changes, skin and hair, low libido, vaginal dryness, breast tenderness, bloating, dizziness, tinnitus, crawling skin and bladder changes, plus your own • Each hot flash (also called a hot flush) or night sweat as its own event, in one tap from the app, Apple Watch, Siri, Shortcuts, the Action Button or Control Center • Periods and cycle length, including irregular and skipped cycles • HRT (patch, gel, spray, pills), supplements and medications, with dose and refill reminders, supply tracking and a suggested site for your next patch (all free) • Blood tests (FSH, estradiol, LH, thyroid, vitamin D, cholesterol and more), blood pressure and bone density • Triggers: timed meals and drinks tagged alcohol, caffeine, hot drink, spicy or sugary food (late meals from 8 pm are tagged for you), plus stress and exercise. Or snap your plate: Solace names the foods and suggests editable tags. No calorie counting • Your Menopause Rating Scale (MRS) score WHAT SOLACE SHOWS YOU • A perimenopause stage estimate (pre, early, late, post), for education, not diagnosis • Patterns in your own logs, for example hot flashes within 3 hours of spicy food or the day after alcohol, or worse sleep before your period • A one-page doctor report (PDF) with symptom charts, period history, medications and test results • Ask Solace: AI answers to menopause questions in plain language SUPPORT BEYOND TRACKING • An HRT-neutral education library with audio: it explains hormonal and non-hormonal options without pushing either • Guided 7-day programs: CBT for sleep and insomnia, hot flashes and mood, plus strength and pelvic floor PRIVACY Your logs stay on your iPhone: no account, no ads, no selling data, and pattern detection runs on your device.
