PRIVATE BY DESIGN Your cycle is personal. Estri keeps it that way: we never sell your data or share it with advertisers, App Lock keeps the app for your eyes only, and your backup lives in your own account. Track honestly, without worrying who's watching. KNOW YOUR PHASE, EVERY DAY Most apps tell you when your period is coming. Estri tells you what's happening in your body today. The Daily Body Brief explains your current cycle phase — menstrual, follicular, ovulation, or luteal — and what it means for your mood, energy, skin, and sleep. Finally understand why some weeks feel unstoppable and others need rest. ACCURATE PREDICTIONS, EVEN WITH IRREGULAR CYCLES Estri's AI learns your unique pattern month after month. Regular or irregular, your predictions for periods, ovulation, and fertile days keep getting sharper. Log flow, cramps, mood, cravings, and dozens of symptoms in seconds. TRYING TO CONCEIVE — OR NOT Planning a pregnancy? Estri pinpoints your fertile window, tracks basal body temperature (BBT) and cervical signs, and shows daily conception chances. Practicing natural family planning or on birth control? Discreet pill, patch, and injection reminders keep you on schedule. And when you get that positive test, Pregnancy Mode continues the journey with you. EAT WITH YOUR CYCLE Cycle syncing, made practical: smart meal suggestions matched to each phase of your cycle, support for cravings, and gentle nutrition guidance that works with your hormones instead of against them. SHARE THE JOURNEY WITH YOUR PARTNER Estri is one of the few period trackers built for two. Share your cycle in real time; your partner receives phase-based tips to understand and support you through PMS, period days, and fertile days — plus custom care notes to send each other. Less guessing, more support. BREATHE THROUGH THE HARD DAYS Somatic breathing and meditation sessions help you relax through cramps and heavy days. Box breathing steadies PMS mood swings and anxious moments. Soundscapes help you unwind and sleep. YOUR HEALTH, ORGANIZED • Doctor Report: export your cycle history as a clean PDF for your gynecologist in one tap. • Water reminder, weight and sleep tracking, clear health charts. • Ask Estri, your AI health assistant, anything about your cycle, symptoms, or hormones. FOR EVERY STAGE OF LIFE From a teen's first period, through trying to conceive, postpartum, perimenopause, and menopause — Estri adapts to your body's story. Estri is not a medical device and does not diagnose, treat, cure, or prevent any condition. Insights are informational — please consult a healthcare professional for medical concerns. Download Estri and meet the period tracker that respects your privacy, explains your body, and keeps your people close. Your cycle, your data, your rules.
