PERIOD. Period & Cycle Tracker

PERIOD. is a period tracker and cycle calendar that predicts your next period, your fertile days and ovulation. Log symptoms in one tap, ask the AI assistant about your cycle, and use PERIOD. baby when you are trying to conceive or pregnant.

Made in Amsterdam, founded by Lisa Volkers. Your data stays in the EU and is never sold.

PERIOD AND CYCLE TRACKING
• Period calendar with predictions that learn from your own cycle
• Ovulation and fertile window predictions
• Symptom tracking: cramps, mood, energy, sleep, skin, libido, pain and more
• Basal body temperature (BBT) and ovulation test logging
• A clear explanation of every cycle phase: menstrual, follicular, ovulation and luteal
• See patterns in PMS and irregular cycles, and bring a doctor report to your appointment

AI ASSISTANT
Ask anything about your cycle, your period or your symptoms and get calm answers that take your own data into account. Our AI never trains on your data.

OVULATION, TRYING TO CONCEIVE AND PREGNANCY: PERIOD. baby
PERIOD. baby is one subscription that grows with you, from cycle tracking to trying to conceive, pregnancy and the time after birth.
• Trying to conceive: your fertile window, a BBT chart, ovulation tests you compare side by side on your own photos, and a place to log a pregnancy test
• Pregnancy week by week: what happens each week, your due date, appointment reminders, a hospital bag checklist, a kick counter and a contraction timer
• After birth: a gentle recovery view, week by week
• If a pregnancy ends, the app meets you with care, and you can go back to your cycle whenever you want

PERIOD. plus

Lisa Volkers and the PERIOD. team

PERIOD. is not a contraceptive and not a medical device. Predictions are estimates and do not replace advice from a doctor or midwife.

Recent changes:
PERIOD. now speaks Hebrew. PERIOD. baby follows the care in Israel, Austria, Switzerland, Italy and Spain, with the check-ups of your own country. Sterilization is now a contraception choice, you change where you are (cycle, pregnant, menopause) right from My health, and picked pregnant by mistake? You can undo it. Arabic and Hebrew read right to left everywhere. Plus small fixes across the app.
