OVA: Period & Cycle Tracker

OVA is a private period tracker, ovulation calculator and cycle calendar that keeps all your data on your phone. No account, no login, no cloud — your menstrual cycle stays yours.

Whether you want to track your period, predict ovulation or understand your fertile window, OVA gives you clear daily insights with zero data collection.

PERIOD TRACKING

Log your dates and get predictions for your next cycle. Built for regular and irregular cycles alike.

OVULATION CALENDAR

See your fertile window, ovulation day and cycle phases on an easy-to-read calendar, with a colour for each phase.

PREGNANCY CHANCE

Each day shows how likely pregnancy is, from very low to peak, based on your cycle history. This is an estimate and not a method of birth control.

REMINDERS

Get a notification 2 days and 1 day before your period, your fertile window and ovulation, plus daily check-in, water and pill reminders. You choose what and when.

FULL PRIVACY

No login. No servers. No data collection. Everything stays on your device. Turn on discreet mode so notifications never mention your period, and lock the app with a 4-digit PIN.

SYMPTOMS AND MOOD

Log your mood, PMS symptoms and personal notes every day.

CYCLE PREDICTIONS

OVA learns from your previous cycles to estimate your next period and fertile days more accurately.

IN YOUR LANGUAGE

OVA is available in over 20 languages, including English, Spanish, Portuguese, Hindi, Arabic, French, Turkish, Indonesian, Bengali, Urdu, German, Japanese, Korean, Chinese, Italian and Russian.

OVA is a tracking tool and is not a substitute for medical advice.

Download OVA and take charge of your menstrual health with complete privacy.
