Now there are apps available that through temperature can reveal whether woman's ovulation cycle has started. It is one of the new birth control ways.

As per experts, a number of young women are now not in favor of hormonal birth control and they are now supporting Natural Family Planning also known as Fertility Awareness Methods (FAM), which is helped by smartphone based apps.

Many experts consider this method to be one of the least successful methods as it is quite complicated to perform correctly.

Many women are using these methods to avoid unwanted pregnancies. With passage of time, the apps are becoming popular as hormonal birth control is much safer than any other method.

The Centers for Disease Control and Prevention said between 1 and 3% of women use FAM as a form of contraception. But as per a study from the University of Iowa, there is a need to raise awareness on the same as if more number of women would know about it then 1 in 5 would consider it as an option.

FAM is referred to as the rhythm method in which women predict their likely fertile days on the basis of the lengths of their cycles.
