Dot Simple Ovulation Calendar

Two
questions.

That's the whole app. No account, no tracking — your answers never leave your device.

1 · Last period began

2 · Usual cycle length

Enter your last period date and cycle length. Dot shows your fertile window, ovulation day, next period, and when a pregnancy test will work.

Everything runs in your browser. No account, nothing stored on a server. Reminders are coded (🟢 🎯 🔵) so your lock screen stays private.

These are estimates. If your cycles vary a lot, expect less accuracy.

This tool provides estimates only and should not be used alone to plan or prevent a pregnancy. Ovulation can vary from cycle to cycle. Talk to your doctor for medical advice. Privacy Policy · Terms of Service
