For any stage of your journey

Trying to conceive

This is our self-proclaimed area of expertise. We’ve helped countless couples get pregnant, some after years of trying with no luck!
Natural Family Planning

iFertracker is applicable for both the Fertility Awareness Method (FAM) and the Sympto-thermal Method of Natural Family Planning. Get a more accurate BBT than traditional oral thermometers, plus record physiological fertility changes in our health log such as cervical mucus, sleep quality, and more.

Hormone tracking during pregnancy

Continue using iFertracker after getting pregnant! It can help you monitor hormone levels during the crucial beginning phases and you can share BBT charts with your doctor to evaluate and promote the health of your pregnancy.
Postpartum return to full fertility

Whether you’re breastfeeding or not, its nice to know when your cycle will return to normal during the postpartum period. You can use iFertracker to monitor your hormones after pregnancy and get an idea of when your ovulatory cycles will return.

“I use BBT tracking every day with my patients and I always hear the same 2 concerns: 1. I forget to take my temperature daily 2. I don’t wake up at the same time every day. The iFertracker solves them both!”

Facebook Review

“In my experience, my sleep times are not consistent, I’m also a mouth breather and after five years ttc and having no luck with other BBT thermometers, it worked for us after one cycle.”

“Easy to use, attractive, and accurate…would definitely recommend the iFertracker to others, especially those who are charting in the postpartum or with an infant at home, or anyone else who wants a more convenient method of tracking their basal body temperature”

“I sometimes move or cuddle my husband before I wake, and I like to pee or drink when I wake, all ruining oral BBT and with iFertracker I can do all these without it affecting my BBT”
