FAQ
Questions Ovulation Calculator owners ask.
- 01
How accurate are the ovulation predictions?
Predictions are based on standard biological models using your provided average cycle length and last period start date. While highly precise for tracking patterns, they should be used as an estimate rather than a medical guarantee.
- 02
What information do I need to provide?
To use the capabilities, you need the ISO 8601 date of your last period start and your average menstrual cycle length in days.
- 03
Can I track different cycle lengths?
Yes, you can provide any positive number for your average cycle length to get customized predictions.
