Ready to Start Using iFertracker?

Open the battery compartment, insert the included CR2025 battery, and close the compartment.

Simply place iFertracker on top of your phone or tablet to connect it!

First, peel back the white side of the adhesive. Then, stick the patch face down on the device so that it is fully flat and evenly surrounding the probe.

Applying the Sensor

Sleep well! Once you wake up, remove the iFertracker sensor from your arm. Then, open the app on your phone or tablet and simply place the sensor on the screen. It will sync with the app and record your overall BBT throughout the night.

You should now be able to review any recorded data in the iFertracker app. The sensor records over 20,000 unique datapoints, ensuring you get the most accurate measurements possible.
