We know how much you care about understanding your reproductive health, especially when it comes to actually getting pregnant. Whether you’re TTC or simply looking to track your cycle with greater precision, iFertracker can help.

Our device continuously monitors body temperature overnight to establish true Basal Body Temperature, which has been found to occur 30 minutes prior to awaking! Moreover, the device pairs with the iFertracker app to provide accurate predictions ahead of time for both your fertile window and ovulation day. Data syncs via Bluetooth and the app automatically converts it into an easy-to-understand BBT chart. It can be easily and comfortably worn under the arm overnight and our advanced algorithm filters out any noise, providing you with unrivaled convenience and accuracy.

No more worrying about waking up in the middle of the night or not moving a muscle in the mornings so you can get an accurate temp! Stay in bed a little longer. Go get that glass of water at 3am. Snuggle up to your significant other before work. FINALLY, you can sleep without worrying about ruining your BBT. Use the iFertracker and see what conceiving with ease really means.

    Helped me get pregnant after only two cycles, so I’m happy with it! No question the device was extremely accurate and the app was easy enough. Was skeptical about the disposable patches because I have sensitive skin, but they ended up being no issue at all – overall definitely recommend for anyone TTC!

    This device is so much more convenient than taking my oral BBT…the iFertracker is SO accurate and comfortable and the app is easy to use. Already looking forward to using this for my next cycle!

    My cycle was off due to multiple miscarriages. This device helped me pinpoint my ovulation day (CD22!) and get pregnant after a few months of wearing. I quickly ran out of patches and wouldn’t pay so much for more, so I just used wearable fashion tape and it worked great. I found sometimes the battery says it is out just a few days after changing it, but if I take it out and put it back in, it “resets” and lasts for weeks. I have shared the device with a friend and sister. We are 2/3 on getting pregnant!

    Easy to use and gets an accurate temp…just having a hard time getting used to the app but I’m sure this will come in time. So far no device or battery issues. Overall I’m happy with my purchase

    after three months of using this product on a daily basis I can pretty confidently say its REALLY accurate. Unlike what I’ve read from most other users on Amazon or their site I’m using it just to track my cycle/ as birth control. i hate hormonal birth control because of the side effects i was getting over the past couple years and this has been a god-send. Everyone who i showed it to seemed to question the comfort right away (under the arm does seem pretty clunky) but for me it wasn’t even noticeable after wearing it for the first night. Its more work than just taking the pill but the bluetooth sync makes it easy and app offers way more insight than just period tracking. Definitely worth the money if you’re looking to ditch the pill- i docked a star for the patches, i just wish the packaging came with more since i’m using it so regularly /:
