Ovulation calculator and period predictor

Enter the first day of your last period and your cycle length. The calculator estimates your ovulation day, fertile window and next three periods.

Estimated for a regular cycle: ovulation about 14 days before the next period, fertile window from 5 days before to 1 day after ovulation. Rosebead learns from your own history, so it gets more accurate over time.

Frequently asked questions

Is Rosebead really free?

Yes. Every feature in Rosebead is free, with no premium tier. Rosebead is made by SaigonScience and does not make money from your data.

How accurate is the ovulation prediction?

Rosebead learns from the cycles you log, so predictions get closer the longer you use it. If you take your basal body temperature or use LH tests, the app uses them to confirm ovulation. It shows a range and how sure it is rather than one exact date.

Is my period data safe?

You can use Rosebead without an account, and then your data stays on your phone. When you sync, your data is encrypted in transit and at rest on our servers. Rosebead never sells your data, and you can delete your account and all of its data at any time.

Do I need an account?

No. Tap Try it without an account and start right away. An account is only needed to sync to another phone or share with a partner, and signing in only takes an email, Google or Apple.

Can I use Rosebead when trying to conceive or pregnant?

Yes. Trying-to-conceive mode highlights your fertile window, temperature and LH tests. Pregnancy mode follows your pregnancy week and due date.

Can my partner see my cycle?

Yes, if you want. Create a share code, your partner enters it in Rosebead and sees your period dates, current phase and how to care for you. Notes, weight and sex are never shared.

Does Rosebead replace a doctor or birth control?

No. Rosebead helps you understand your cycle and suggests when it may be worth seeing a doctor, but it is not a form of contraception and does not replace medical advice.

Is Rosebead on iPhone and Android?

Rosebead is made for both iPhone and Android, in English and Vietnamese.
