Could the ovulation date also be found for those with an irregular menstrual cycle?

Yes. himama calibrates the menstrual cycle automatically. It is able to identify the current period automatically based on the change’s curve of your BBT and previous menstrual cycles, as well as judge whether the ovulation date comes after synchronizing your temperature. So it is suggested if you want to know what the best day to get pregnant is based on your ovulation, you use the thermometer every day and sync it with the himama APP in order to track your ovulation.
