What it does
Knows what is coming
Your next period, fertile window and ovulation day, learned from the dates you log.
Tells you if you are normal
Compares your cycle to the typical range and says so plainly. It never diagnoses anything.
Finds your patterns
Which symptoms follow your cycle, and on which day, once there is enough history.
Reminds you
A heads up two days before and on the day. Scheduled on your phone, hidden on your lock screen.
Twelve months ahead
Every upcoming period and fertile window for the year. Other apps charge for this.
Locks behind a PIN
A curtain over the app for anyone who shares a phone.
Free, including the parts others charge for
