Researchers in the UK have developed a fertility tracking app, which could be a game changer for women wanting to become pregnant.

The app is being touted as so accurate that it can also work the other way – as contraception for women wishing to not become pregnant.

The app, Natural Cycles, is the brainchild of Dr. Elina Berglund, one of the world’s top physicists and part of the Nobel Prize-winning team that discovered the Higgs-Boson.

Of course there are currently hundreds of fertility-related apps available for smartphones, but Natural Cycles is different in that it is a combination of an algorithm along with the subject’s own body temperature, which is logged over a certain period.

The app, which costs around $14 per month, is able to accurately track the subtle variations in the body temperature of the phases that comprise the menstrual cycle.

A woman simply takes her body temperature at the start of the day and enters it into the app. It is then able to alert the woman to her fertility level on that day, and also when peak fertility is reached.

The app is also apparently able to learn an individual’s cycle pattern, enabling her to predict an ovulation date.
