Frequently Asked Questions

Our application aggregates multiple parameters to determine the most favorable days for conception.
As you may already know, the day of ovulation and the five days preceding it are the most suitable period for ovum fertilization – that is because the sperm remains viable inside female body for as long as five days after sexual intercourse.

A 100% accurate ovulation day prediction is possible only with clinical equipment and the use of ultrasound. Nevertheless, by collecting and organizing information, the Selin application can determine ovulation days with a high chance of accuracy.

The application monitors the fertile window. Keep track of the highlighted dates in the calendar, which indicate favorable period for conception. Naturally, the day of ovulation is the most favorable one.
By regularly including additional parameters, you can make the forecasts even more accurate.
