Notice cycle changes, follow your pregnancy and remember what to ask your doctor. Olisora is your period, ovulation and pregnancy tracker, with support for your own wellbeing and your baby Choose what matters to you now. Olisora uses it to personalize advice, conversations and your weekly wellbeing review. Understand changes in your cycle When dates shift or PMS symptoms return, start with your own history. Log period start and end dates, flow, pain, mood and sleep. Compare menstrual cycles and see an estimated date for your next period. Keep your history while trying to conceive The ovulation calendar shows estimated fertile days. Record pregnancy test results and keep lab results and completed examinations together. The Readiness Index organizes cycle and lifestyle information; it does not assess your ability to conceive. Remember your contraception schedule You do not have to be trying for a baby to care for your cycle. Keep a history of your chosen method and set reminders for pills, patches, rings or IUD and implant replacement. You enter the schedule; the calendar does not identify “safe days.” Understand lab terms before your appointment Your results have arrived, but the consultation is still ahead. Save lab results, ultrasound reports and other documents, and note your questions. Discuss selected records with Olisora to understand terms and prepare for your doctor. Medical assessment belongs to a clinician. Remember appointments and prescribed medications Plan visits, save your doctor’s recommendations and enter prescribed medicines and vitamins. Set schedules and reminders, and mark doses taken or skipped. Olisora does not choose medicines or change doses. Follow your pregnancy week by week Learn about your pregnancy stage and your baby’s development. When nausea, tiredness or other symptoms affect your day, record when they happen. Your pregnancy diary helps you recall changes between appointments. Make room for your own care after birth Record sleep, mood, recovery and the return of your period. The first-year checklist helps you remember your own wellbeing while caring for your child, without pressure to return to your previous weight. See how your baby is growing One weigh-in does not show the whole history. In your baby diary, record dated height and weight, symptoms, measured temperature, new skills and first teeth. Keep vaccination records and plan visits. Each child has a separate history to discuss with the pediatrician. Bring weight and blood pressure changes to your doctor Record weight, blood pressure and pulse, and view charts and history. Pressure records, reminders and imports from Apple Health on iOS or Health Connect on Android are free. The app does not measure pressure. With Premium, discuss pressure, nutrition, recipes and recovery; pregnancy support does not offer weight-loss advice. Talk about what matters to you Tell Olisora how you feel, complete a wellbeing checkup and revisit your observations in a weekly review. You choose which medical records to share. Open a relevant tracker directly from the conversation. Premium is required for unlimited conversations, blood pressure discussions, personal weight, nutrition and recovery advice, document recognition and PDF reports for your doctor. Review recognized results for accuracy. Important Olisora helps you keep observations and provides information. She does not diagnose, prescribe treatment or replace a doctor. Ovulation predictions are estimates: they do not confirm ovulation, guarantee conception or serve as contraception. For concerning symptoms or changes in usual baby movements, seek medical help without waiting for Olisora’s reply.

If you don't recognize yourself the week before your period — snapping at people, crying, not sleeping, unable to focus — you're not alone. This is what severe PMS and PMDD, premenstrual dysphoric disorder, can look like. Code Red is built specifically for this. Not another period calendar, but a diary that helps you understand what's happening to you and get through the hard days more easily. AN AI ASSISTANT THAT KNOWS YOUR CYCLE • Tell it how you feel: it goes through your symptoms, explains how they relate to your cycle phase and suggests what may help right now • Offers exercises based on cognitive behavioral therapy • Sees your entries only with your permission PMS & PMDD MODE • A daily rating of 24 symptoms structured like the DRSP, the scale doctors use when assessing PMDD • After a couple of cycles you can see which symptoms come back and on which days • A morning heads-up when, based on past cycles, a hard day may be close CYCLE & FORECAST • Your cycle day and phase on the home screen • Period and hard-day forecast based on your own history WIDGETS • Cycle day, days until your period and your day right on the Home Screen — no need to open the app APPLE HEALTH • Period days and symptoms sync both ways • Sleep and resting heart rate are included in your doctor report FOR YOUR DOCTOR • A PDF report or spreadsheet for any period up to a year • Medications and supplements with reminders in the right cycle phase Code Red does not diagnose and does not replace a doctor. The period forecast is not suitable for contraception.
